Python Pool: Python Code to Convert a Table to First Normal Form
2020-12-24 06:17:47
Python has thousands of modules and libraries to help you with tabular data. These datasets can contain many different ways in which the data can be represented. Before inferring any valuable information for the tables, you need to apply some filters and normalizations to understand. There are thousands of ways to pre-process and clean your data in python. This is where the normalization (first normal form) comes into play. In layman terms, First Normal Form (1NF) refers to certain relations in the dataset. These relations ensure that every domain in the table has a different attribute in different rows. In this post, we will use Python Code to Convert a Table to First Normal Form Form by using the pandas’ library. Before jumping straight to the code, let’s understand more about the first normal form and its rules.

Python Pool: NUMPY ARGWHERE WITH EXAMPLES IN PYTHON
2020-12-22 02:25:59
Hello geeks and welcome in this article, we will cover NumPy argwhere. Along with that, we will also look at its syntax and parameters involved. For a better understanding, we will also look at various examples. But first, let us try to get a general idea about the function itself. Numpy is a powerful mathematical library of Python that provides us with many useful functions. One such useful function of NumPy is argwhere. This helps the user by providing the index number of all the non-zero elements in the matrix grouped by elements. We can use this function with a limit of our own also that we will see in examples. But at first, let us look at its syntax.

Python Pool: NUMPY MEDIAN() WITH EXAMPLES IN PYTHON
2020-12-22 01:29:06
Hello geeks and welcome in today’s article, we will discuss NumPy Median(). Along with that, we will also look at its syntax and various parameters. We will also look at various examples that will help us understand the topic better. Median is one of the 3 M’s of statistics. Median is the central value of data when arranged in a particular order. In general, the formula for median calculation is (n+1)/2th term for the odd number of terms and mean of (n/2)th and (n/2 +1)th term for the even number of terms. NumPy being a powerful mathematical library of Python, provides us with a function Median. So we can conclude that NumPy Median() helps us in computing the Median of the given data along any given axis. Now let us look at the various aspects associated with it one by one.

This dataframe is used for demonstration purpose. import pandas as pddf = pd.DataFrame({"col1" : range(1,5), "col2" : ['A A','B B','A A','B B'], "col3" : ['A A','A A','B B','B B'] }) Filter a value A A in column col2In order to do reference of a variable in query, you need to use @. Mention Value Explicitlynewdf = df.query("col2 == 'A A'")Reference Method myval1 = 'A A'newdf = df.query("col2 == @myval1") How to pass column name as a variable in queryInstead of filter value we are referring the column which we want to use for subetting or filtering. myvar1 = 'col2'newdf2 = df.query("{0} == 'A A'".format(myvar1)) {0} takes a value of variable myvar1. "{0} == 'A A'".format(myvar1) returns "col2 == 'A A'" Incase you want to pass multiple columns as variables in query. Here we are using columns col2 and col3.myvar1 = 'col2'myvar2 = 'col3'newdf2 = df.query("{0} == 'A A' & {1} == 'B B'".format(myvar1, myvar2)) "{0} == 'A A' & {1} == 'B B'".format(myvar1, myvar2) is equivalent to "col2 == 'A A' & col3 == 'B B'" How to handle space in column nameLet's rename column col2 by including a space in between for illustration purpose. df.rename(columns={'col2':'col 2'}, inplace = True) By using backticks `` you can pass a column which contains space. myvar1 = '`col 2`'newdf = df.query("{0} == 'A A'".format(myvar1))

Scientists learn programming as they need it. Some of them learn it in college, but even if they do, that's not their focus. It's not surprising that sharing the software used for scientific research and papers is spotty, at best. And what about testing? We'd hope that the software behind scientific research is tested. But why would we expect that? We're lucky if CS students get a class or two that even mentions automated tests. Why would we expect other scientists to just know how to test their code?

Python Pool: How to Clear Plot in Matplotlib Using clear() Method
2020-12-18 03:15:35
Hello programmers, in today’s article, we will discuss Matplotlib clear plot in python. Matplotlib is a library in Python, which is a numerical – mathematical extension for NumPy library. The figure module of the Matplotlib library provides the top-level Artist, the Figure, which contains all the plot elements. The figure module is used to control the subplots’ default spacing and top-level container for all plot elements. The Axes Class contains the figure elements: Axis, Tick, Line2D, Text, Polygon, etc., and sets the coordinate system. The instances of Axes supports callbacks through a callbacks attribute. The Axes.clear() in the axes module of the matplotlib library is used to clear the axes. Thus, the Matplotlib figure.clear() and axes.clear() is used to clear figure and axes, respectively. Here are the syntax and parameters of the Matplotlib clear plot function.

PyCon: Announcing the Location for PyCon US 2022/2023
2020-12-14 16:27:40
We’re planning for PyCon US 2022 and 2023 to be held in-person. It may seem strange to announce an in-person conference in the middle of a global pandemic, so let’s start by explaining why:Usually, we announce PyCon US host cities shortly after we’ve made our selection, and this year we hoped to make this announcement during the close of PyCon US 2020 in Pittsburgh. Instead, the immediate future of PyCon changed. We quickly cancelled the in-person portion of PyCon US 2020, and moved PyCon US 2021 to a fully-online event. None of this changed our plans for 2022, because we made these plans in 2019. We seek out host cities many years in advance of PyCon US so that we can find space to hold a 10-day event with 3500 attendees on dates that do not clash with major holidays and religious observances. We found our host city, and signed contracts and paid deposits with venues, caterers, hotels, and other vendors in Q3 2019, months before the Pandemic had started. Those contracts are still in place.So, as long as the situation in the US makes it safe to hold an in-person event in 2022, PyCon US 2022 will be held in person. Of course, we’ll be monitoring the situation closely, and we’ll change our plans if we need to, but we’re hoping that it’ll be safe to see many of you in person, and we’re excited to be able to welcome you to our first in-person event in three years.

How can you set up Tailwind CSS for your Django app on Heroku? In this article, we&rsquo;ll see how I did exactly that recently. I have a side project that uses Tailwind CSS. To get started quickly, I used the version from a Content Delivery Network (CDN) as Tailwind describes in the documentation. This worked fine initially while I got my project started, but the CDN version is huge (around 3MB).

The No Title® Tech Blog: Book review - Foundations of Deep Reinforcement Learning, by Laura Graesser and Wah Loon Keng
2020-12-04 01:00:00
Deep Reinforcement Learning is a somewhat new field within Machine Learning or Artificial Intelligence (you may pick your favorite term between these two, even if they’re not strictly the same), which combines Deep Learning and Reinforcement Learning and is based on the general idea that an agent can learn by observing its actions and their consequences. No, it is not a return to John B. Watson and B. F. Skinner’s behavioral psychology. We are talking, instead, about a set of pretty advanced machine learning algorithms that, when properly mastered, allow computers to achieve remarkable results in some complex tasks. That’s what this book is about, so let’s dive in…

Python Pool: Numpy Squeeze in Python With Examples
2020-12-01 06:41:29
Hello programmers, in this article, we will discuss the Numpy squeeze function in Python. The squeeze () function is used when we want to remove single-dimensional entries from the shape of an array. Whenever we want to change the shape of a three-dimensional array to a two-dimensional array, we make use of the squeeze() function in NumPy. Hence, the squeeze() function returns the input array with the subset of the dimension having a length equal to one removed from the array. Before we cite examples to show the working of numpy.squeeze() function, let me just brief you about the syntax, parameters, and return type of the same.

Building a complete web application requires expertise in a wide range of disciplines. As a result it is often the work of a whole team of engineers to get a new project from idea to production. Meredydd Luff and his co-founder built the Anvil platform to make it possible to build full stack applications entirely in Python. In this episode he explains why they released the application server as open source, how you can use it to run your own projects for free, and why developer tooling is the sweet spot for an open source business model. He also shares his vision for how the end-to-end experience of building for the web should look, and some of the innovative projects and companies that were made possible by the reduced friction that the Anvil platform provides. Give it a listen today to gain some perspective on what it could be like to build a web app.

So you're excited about WebAssembly? You're not alone, many are. WebAssembly has huge opportunities that extend way past just compiling non JavaScript code to make it run in the browser. The reason for this is that it is quickly becoming a widely supported compilation target for a range of runtimes. This lets one ship a custom WebAssembly runtime to run your stuff and then update the code that is running on it trivially across a variety of environments. It's a more modern take of Java's “compile once run everywhere” philosophy.

In a software project writing code is just one step of the overall lifecycle. There are many repetitive steps such as linting, running tests, and packaging that need to be run for each project that you maintain. In order to reduce the overhead of these repeat tasks, and to simplify the process of integrating code across multiple systems the use of monorepos has been growing in popularity. The Pants build tool is purpose built for addressing all of the drudgery and for working with monorepos of all sizes. In this episode core maintainers Eric Arellano and Stu Hood explain how the Pants project works, the benefits of automatic dependency inference, and how you can start using it in your own projects today. They also share useful tips for how to organize your projects, and how the plugin oriented architecture adds flexibility for you to customize Pants to your specific needs.

Real Python: Python enumerate(): Simplify Looping With Counters
2020-11-18 14:00:00
In Python, a for loop is usually written as a loop over an iterable object. This means you don’t need a counting variable to access items in the iterable. Sometimes, though, you do want to have a variable that changes on each loop iteration. Rather than creating and incrementing a variable yourself, you can use Python’s enumerate() to get a counter and the value from the iterable at the same time!

The basic installation format for users who install packages via pip is the wheel format. Wheel names are composed of four parts: a package-name-and-version tag (which can be further broken down), a Python tag, an ABI tag, and a platform tag. More information on the tags can be found in PEP 425. So a package like NumPy will be available on PyPI as numpy-1.19.2-cp36-cp36m-win_amd64.whl for 64-bit windows and numpy-1.19.2-cp36-cp36m-macosx_10_9_x86_64.whl for macOS.

In other instances, this activity might be the first step in a more complex data science analysis. In pandas, the groupby function can be combined with one or more aggregation functions to quickly and easily summarize data. This concept is deceptively simple and most new pandas users will understand this concept. However, they might be surprised at how useful complex aggregation functions can be for supporting sophisticated analysis.

Anwesha Das: Using Mailvelope with Yubikey in Linux
2020-11-07 16:01:40
Mailvelope is an extension on web browsers to send end to end encrypted emails. This is a good option available to the users to send end to end encrypted without changing the email service they use. It is licensed under AGPL v3, making it Free and Open Source software. The code is there in Github for the community to have a look. This can be added as an extension to the - Chrome, Firefox and Edge browsers to securely encrypt emails with PGP using your email providers. ​ Mailvelope does provide end to end encryption for the email content but does not protect the metadata (subject, IP address of the sender) from third parties. As most of the email encryption tools, it does not work on the mobile browser. There is a detailed user guide on Mailvelope from the Freedom of the Press Foundation, which is really helpful for the new users. ​ By default, Mailvelope uses its own keyring. To use my Yubikey along with GnuPG keyring, I had to take the following steps: ​

 It's been almost two months since my last blog post and I feel guilty of not haven't taken the time to write more regularly.  I should really tell you about how fantastic Will McGugan's Rich is, and how I have customized it for my projects. I should also tell you how Sylvain Desodt's DidYouMeanPython has been influencing Friendly-traceback latest developments. Also worthy of note is how Alex Hall's FutureCoder project is incorporating so many neat tools that it feels like a real honour that he has incorporated Friendly-traceback in it.

Podcast.__init__: The Journey To Replace Python's Parser And What It Means For The Future - Episode 285
2020-10-19 23:20:20
The release of Python 3.9 introduced a new parser that paves the way for brand new features. Every programming language has its own specific syntax for representing the logic that you are trying to express. The way that the rules of the language are defined and validated is with a grammar definition, which in turn is processed by a parser. The parser that the Python language has relied on for the past 25 years has begun to show its age through mounting technical debt and a lack of flexibility in defining new syntax. In this episode Pablo Galindo and Lysandros Nikolaou explain how, together with Python’s creator Guido van Rossum, they replaced the original parser implementation with one that is more flexible and maintainable, why now was the time to make the change, and how it will influence the future evolution of the language.

Anarcat: SSH 2FA with Google Authenticator and Yubikey
2020-10-19 15:08:55
About a lifetime ago (5 years), I wrote a tutorial on how to configure my Yubikey for OpenPGP signing, SSH authentication and SSH 2FA. In there, I used the libpam-oath PAM plugin for authentication, but it turns out that had too many problems: users couldn't edit their own 2FA tokens and I had to patch it to avoid forcing 2FA on all users. The latter was merged in the Debian package, but never upstream, and the former was never fixed at all. So I started looking at alternatives and found the Google Authenticator libpam plugin. A priori, it's designed to work with phones and the Google Authenticator app, but there's no reason why it shouldn't work with hardware tokens like the Yubikey. Both use the standard HOTP protocol so it should "just work".

Real Python: Python Booleans: Optimize Your Code With Truth Values

The way that applications are being built and delivered has changed dramatically in recent years with the growing trend toward cloud native software. As part of this movement toward the infrastructure and orchestration that powers your project being defined in software, a new approach to operations is gaining prominence. Commonly called GitOps, the main principle is that all of your automation code lives in version control and is executed automatically as changes are merged. In this episode Victor Farcic shares details on how that workflow brings together developers and operations engineers, the challenges that it poses, and how it influences the architecture of your software. This was an interesting look at an emerging pattern in the development and release cycle of modern applications.

Podcast.__init__: Threading The Needle Of Interesting And Informative While You Learn To Code - Episode 283
2020-10-06 00:05:23
Learning to code is a neverending journey, which is why it’s important to find a way to stay motivated. A common refrain is to just find a project that you’re interested in building and use that goal to keep you on track. The problem with that advice is that as a new programmer, you don’t have the knowledge required to know which projects are reasonable, which are difficult, and which are effectively impossible. Steven Lott has been sharing his programming expertise as a consultant, author, and trainer for years. In this episode he shares his insights on how to help readers, students, and colleagues interested enough to learn the fundamentals without losing sight of the long term gains. He also uses his own difficulties in learning to maintain, repair, and captain his sailboat as relatable examples of the learning process and how the lessons he has learned can be translated to the process of learning a new technology or skill. This was a great conversation about the various aspects of how to learn, how to stay motivated, and how to help newcomers bridge the gap between what they want to create and what is within their grasp.

I evaluated three different data types: an RDKit ExplicitBitVect, a GMP mpz integer, and a byte string. I found that the byte string was fastest, at about 5 seconds per search. All three programs worked by parsing and testing each FPS record in sequence. A scan search like this requires essentially constant memory overhead no matter the size of the FPS file.

Sumana Harihareswara - Cogito, Ergo Sumana: Changes Coming To Pip In October 2020
2020-09-30 16:24:17
SHORT VERSION: I'm working on improving the Python packaging toolchain, foundational work that will (in the long run) make the whole Python experience way less confusing. In the short term this may mess with some people's workflows, so we want lots of people to hear about it now. The pip team made a 2-minute video to explain what's up: We are also doing user experience studies, and want you to sign up if you ever do anything with Python (whatever your level of skill/experience). Please boost this toot or retweet this tweet if you want to help us get the word out. MORE DETAILS: Computers need to know the right order to install pieces of software ("to install x, you need to install y first"). So, when Python programmers share software, like when they publish packages on the Python Package Index or internally in large companies, they have to precisely describe those installation prerequisites. And then pip needs to navigate tricky situations when it gets conflicting instructions. Up until now, pip's been very inconsistent in handling this stuff, which makes it easy for your Python environment to get messed up. That's why we successfully applied for $407K in funding from Mozilla and the Chan Zuckerberg Initiative to finish and roll out a proper dependency resolver for pip. The goal is that pip will get better at handling that tricky logic, and easier for you to use and troubleshoot. You can test the new behavior (in beta) right now by using an optional flag in pip 20.2. And in pip 20.3, coming in October, the new behavior will be the default. Once you're using the new resolver, pip is going to be stricter and more consistent. So things won't mysteriously break as much, and we can add more features that lots of people want. But! Right now, a ton of people unknowingly have Jenga towers of wobbly dependencies in their environments and will run into pain when we make the resolver stricter and more consistent. And this may lead to you getting stuck in troubleshooting, assuming that pip caused the problem, when actually the deeper cause is conflicts among how your upstreams specify requirements (TensorFlow just fixed a related thing, for example). So: We're trying to get Python users to try out the beta of the new resolver that's available in the current stable release of pip (20.2), fix your own environments, report bugs in your upstreams in advance, and report bugs to us so we can fix them in the next couple weeks. We started spreading the word about this a few months ago. And now: video! People watch videos, I hear? I hope this helps.

Real Python: Python's map(): Processing Iterables Without a Loop
2020-09-30 14:00:00
Python’s map() is a built-in function that allows you to process and transform all the items in an iterable without using an explicit for loop, a technique commonly known as mapping. map() is useful when you need to apply a transformation function to each item in an iterable and transform them into a new iterable. map() is one of the tools that support a functional programming style in Python.

Andrew Dalke: Simple k-NN FPS Tanimoto and cosine similarity search
2020-09-29 12:00:00
Yesterday I developed an simple program to search chembl_27.fps.gz for records with a Tanimoto similarity of at least 0.7 to caffeine. I started by mentioning the 1986 paper by Willet, Winterman, and Bawden Implementation of nearest-neighbor searching in an online chemical structure search system. As you can read from the title, that paper does a k-nearest neighbor search (k-NN search, also called a top-N search), and compares a Tanimoto similarity search to a cosine similarity search. So really, I'm only halfway there. In this essay I'll go the other half and implement the nearest neighbor search. As before, this code will do almost no error handling, and will only work for the uncompressed chembl_27.fps in the local directory.

Podcast.__init__: Solving Python Package Creation For End User Applications With PyOxidizer - Episode 282
2020-09-29 01:50:02
Python is a powerful and expressive programming language with a vast ecosystem of incredible applications. Unfortunately, it has always been challenging to share those applications with non-technical end users. Gregory Szorc set out to solve the problem of how to put your code on someone else’s computer and have it run without having to rely on extra systems such as virtualenvs or Docker. In this episode he shares his work on PyOxidizer and how it allows you to build a self-contained Python runtime along with statically linked dependencies and the software that you want to run. He also digs into some of the edge cases in the Python language and its ecosystem that make this a challenging problem to solve, and some of the lessons that he has learned in the process. PyOxidizer is an exciting step forward in the evolution of packaging and distribution for the Python language and community.

Andrew Dalke: Mixing text and chemistry toolkits
2020-09-25 12:00:00
This is part of a series of essays about using chemfp to work with SD files at the record and simple text level. Chemfp has a text toolkit to read and write SDF and SMILES files as records, rather than molecules. It also has a chemistry toolkit I/O API to have a consistent way to handle structure input and output when working with the OEChem, RDKit, and Open Babel toolkits. In this essay I'll combine the two, so chemfp reads records from an SD file, which are then passed to a chemistry toolkit for further parsing, then chemfp adds a data item back to the original record instead of converting the toolkits molecule into a new SDF record.

Python⇒Speed: The mmap() copy-on-write trick: reducing memory usage of array copies
2020-09-17 00:00:00
Let’s say you have an array, and you need to make some copies and modify those copies. Usually, memory usage scales with the number of copies: if your original array was 1GB of RAM, each copy will take 1GB of RAM. And that can add up.

In this article, I will compare their performance and discuss when a list comprehension is a good idea, and when it’s not.

Real Python: Numbers in Python
2020-09-16 14:00:00
You don’t need to be a math whiz to program well. The truth is, few programmers need to know more than basic algebra. Of course, how much math you need to know depends on the application you’re working on. In general, the level of math required to be a programmer is lower than you might expect. Although math and computer programming aren’t as correlated as some people might believe, numbers are an integral part of any programming language, and Python is no exception.

However, there can be some challenges in cleaning and formatting the data before analyzing it. In this article, I will discuss how to use pandas read_html() to read and clean several Wikipedia HTML tables so that you can use them for further numeric analysis.

Andrew Dalke: Similarity principle variations
2020-09-14 12:00:00
Maggiora, Vogt, Stumpfe, and Bajorath in their 2014 J. Med. Chem miniperspective Molecular Similarity in Medicinal Chemistry write: In the context of a seminal book publication8 that appeared in the early 1990s when molecular similarity analysis first became popular, the similarity property principle (SPP) emerged, which stated that similar compounds should have similar properties, the most frequently studied property being biological activity. That citation "8" is Concepts and applications of molecular similarity, edited by Mark A. Johnson and Gerald M. Maggiora (1990), published by Wiley. This is an often-cited reference in the cheminformatics literature. Google Scholar knows about 1411 citations to it.

Ned Batchelder: Song-basket
2020-09-13 21:03:20

I can choose a playlist (the basket), and then as I surf around Spotify, it lets me add the current song to the basket with one click. It also shows me whether the current song is already in the basket or not, which they often are. If the song is already in the basket, I don’t have to think about whether to add it, and I don’t have to deal with the annoying “Add duplicate?” question.

One of the first things you encounter while learning the basics of programming is the concept of strings. Similar to various programming languages, Python strings are arrays of bytes representing Unicode characters - an array or sequence of characters. Python, unlike many programming languages, doesn’t have a distinct character datatype, and characters are considered strings of length 1.

Andrew Dalke: Similarity principle in legal cases
2020-09-11 12:00:00
Read enough cheminformatics papers and you'll eventually come across the a variation of the similarity principle or similar property principle or molecular similarity principle. Here's a 2020 example from the JCIM paper Assessing the Performance of Mixed Strategies To Combine Lipophilic Molecular Similarity and Docking in Virtual Screening: Under the framework of the similarity principle property,5 which assumes that similar compounds should have similar properties, a plethora of methods have been developed to disclose structure-activity relationships, derive pharmacophores to rationalize the biological activity, and perform similarity measurements in the search of novel chemical scaffolds. and here's the only one in J. Cheminformatics, titled Optimal assignment methods for ligand-based virtual screening by Jahn, Hinselmann, Fechner and Zell (2009): The underlying assumption of ligand-based approach is that similar structures have similar biological activity. Maggiora and Johnson [8] introduced the similarity-property principle that implies that the chemical similarity can be related to the biological activity of structures. In both cases that citation is to Johnson and Maggiora's (ed.) seminal work Concepts and Applications of Molecular Similarity.

There is almost no overlap between those methods and legal molecular similarity. Two essays ago I covered patent law, where patentability depends on the expectations of a "person having ordinary skill in the art". In my previous essay I covered drug control law, which in the US seems based on the ability of laypeople to judge chemical similarity based on 2-D structure.

Abhijeet Pal: Python’s @property Decorator Explained
2020-09-10 09:47:51
Python provides a built-in @property decorator which makes usage of getter and setters much easier in Object-Oriented Programming. Properties are useful because they allow us to handle both setting and getting values in a programmatic way but still allow attributes to be accessed as attributes. Let’s look at one example. class Circle(): def __init__(self, radius): self.diameter = 2*radius def circumference(self): return 3.14*self.diameter @property def radius(self): return self.diameter / 2 @radius.setter def radius(self, radius): self.diameter = 2 * radius In Python, @property is a built-in decorator that creates and returns a property object. The @property decorator is internally taking the bounded method as an argument and returns a descriptor object. That descriptor object then gets the same name of the old method therefore the setter method is bound to that method i.e. @radius.setter the method getter is referring too. Now let’s create an object and get its circumference c = Circle(radius=2) c.circumference() Output: 12.56 Next, let’s use the radius setter method. c.radius = 3 c.circumference() Output: 18.84 Properties solve several problems. The main one is that they allow you to substitute a method …

Logic errors occur when an otherwise valid program doesn’t do what was intended. Logic errors cause unexpected behaviors called bugs. Removing bugs is called debugging.

Abhijeet Pal: Python’s @classmethod and @staticmethod Explained
2020-09-09 11:39:26
For beginners who are learning object-oriented programming in Python, it is very essential to have a good grasp over class method and static method for writing more optimized and reusable code. Also, it is very common for even experienced programmers coming from different languages to get confused between these two. In this article, we will develop a better understanding of the class method and static methods in Python. Static Method in Python A @staticmethod is a method that knows nothing about the class or instance it was called on unless explicitly given. It just gets the arguments that were passed, no implicit first argument and It’s definition is immutable via inheritance. In simpler words a @staticmethod  is nothing more than a regular function defined inside a class that doesn’t have access to the instance therefore It is callable without instantiating the class. Syntax: class ClassName: @staticmethod def method_name(arg1, arg2, ...): ... We use the @staticmethod decorator for defining a static method in Python, here you can observe that the static method is not taking self as an argument for the …

Sumana Harihareswara - Cogito, Ergo Sumana: Breaking Release Bottlenecks -- What Changeset Can Do
2020-09-09 02:13:51
Pipenv's maintainers had not released a new version since November 2018, and users were concerned (in many cases switching to competitors). In early March of this year, someone suggested that perhaps the official Python Packaging User Guide should stop recommending it. I saw that suggestion and went into the relevant Internet Relay Chat (IRC) channel to nudge one of pipenv's maintainers and to ask: what do you need? What's blocking you? Dan Ryan ("techalchemy") knew what was blocking him: techalchemy: if you're purely evaluating 'how do we release the code', yeah I might just be the main roadblock? techalchemy: someone to yell at me to stop doing things that are not related to the goal? techalchemy: lol sumanah: let us assume that a successful release -- even as a pre-alpha -- is something that does not instantly break every user's life techalchemy: yeah longer term planning though would require tech writing for sure and onboarding help, god do I struggle with that techalchemy: have you heard me explain something... sumanah: if you JUST want someone to yell at you to stop doing those unrelated things, just for about a month, then that can be cheaper .... would you actually _listen_ to that person? techalchemy: historically speaking, I'd insist I was doing something important briefly but probably reassess, I do know what needs to happen sumanah: :-) ok. So, how frequently do you need those checkins? like, 4 times a day, 5 days a week? techalchemy: hopefully not that much, but I could see a few checkins being helpful especially if we were also onboarding some new people sumanah: techalchemy: ~10 minutes of conversation, via IRC, 4 times a day, 5 days a week, for 3 weeks.... That would have worked out to about ten hours. We underestimated how long it would take Dan to address some nasty continuous integration bugs, so instead of three weeks it took three months. Over those months, I donated about 15 hours of my time, helping him release two betas, then a stable version in May. Given my current hourly rates, this constitutes a donation worth a few thousand dollars, which is infinitesimal compared to the value unlocked by expediting a pipenv release. Dan needed someone to help him with prioritization, release management, and communications. So I: rewrote the release checklist and kept it updated updated GitHub issues and tweeted to keep users apprised, and to ask them for help testing the beta releases (including suggestions of specific cases to test, which I later adapted for pip) created draft outlines for him to fill in so he could write a status update and the beta release announcement for mailing lists/forums closed duplicate "is pipenv dead?" issues and updated a longer-term issue about maintainer needs, roadmap, etc. made a few documentation pull requests: nudged Dan and Ernest to move Pipenv docs from a nonfunctioning domain to pipenv.pypa.io, fixed a bunch of obsolete links, and edited Dan's "how to release" docs and made a pull request to move them into the repo and out of an ephemeral hackpad every few days, checked in with Dan via IRC or email (we also had a few videocalls) to help him stay on task Phil Gyford noticed that initial IRC conversation and said: It's kind of fascinating as an example of bottlenecks in open source development and the importance of project managers. And Yoz Grahame replied: I regularly have conversations like this, and it's a toss-up as to which of the two roles I play. Yeah. An external perspective can help a lot. And, ideally, a project manager is a supportive accountability partner who helps with the bits you're not great at. If you/your company depends on an open source project and you're getting annoyed or worried because the release cadence has slowed to a standstill, there's a strong chance you can turn that around. If someone on your team can spend a few hours complementing the existing maintainers and helping unblock them, that could save you a bundle compared to forking or switching dependencies. Try talking with the maintainers about what they need. And I do mean talking, as in, synchronous conversation via voice or chat, so you can build some trust and get the kind of conversation you see in the IRC log above. Or: contact Changeset Consulting for a free initial 30-minute chat. Maybe it'll only cost you a few thousand dollars to get that bottleneck unblocked. Let's find out!

My previous essay did the same for patents.

Podcast.__init__: Digging Into Dagster: An Opinionated Open Source Framework For Data Orchestration
2020-09-07 22:35:39
Data applications are complex and continually evolving, often requiring collaboration across multiple teams. In order to keep everyone on the same page a high level abstraction is needed to facilitate a cross-cutting view of the data orchestration across integration, transformation, analytics, and machine learning. Dagster is an innovative new framework that leans on the power and flexibility of Python to provide an extensible interface to the complete lifecycle of data projects. In this episode Nick Schrock explains how he designed the Dagster project to allow for integration with the entire data ecosystem while providing an opinionated structure for connecting the different stages of computation. He also discusses how he is working to grow an open ecosystem around the Dagster project, and his thoughts on building a sustainable business on top of it without compromising the integrity of the community. This was a great conversation about playing the long game when building a business while providing a valuable utility to a complex problem domain.

Abhijeet Pal: Python callable() Explained
2020-09-07 06:42:06
In programming, a callable is something that can be called. In Python, a callable is anything that can be called, using parentheses and maybe with some arguments. Functions, Generators, and Classes are inherently callable in Python. The callable() method takes an object and returns a boolean. True – if the object is callable False – if the object is not callable The callable() method checks if the object is either of the two – An instance of a class with a __call__ method Is of a type that has a which indicates callability such as in functions, classes, etc. or has a non-null tp_call (c struct) member. Since functions are callable in Python. def my_function(): print("Hi, I'm a function") callable(my_function) Output True This indicates that every time we create a function, Python creates a callable object for it. You can also verify the presence of __call__ attribute. my_function.__call__ Output <method-wrapper '__call__' of function object at 0x7f08706d5840> Similarly for a Class, class MyClass(): def my_method(self): print("Hi, I am a class method") callable(MyClass) Output True However, if you create an object and …

Abhijeet Pal: Django + AJAX : How to use AJAX in Django Templates
2020-09-01 16:33:47
AJAX or Asynchronous JavaScript And XML is a set of web development techniques using web technologies on the client-side to create asynchronous web requests. In simpler words, AJAX allows web pages to be updated asynchronously by exchanging data with a web server behind the scenes. This means that updating parts of a web page is possible, without reloading the whole page. We can make AJAX requests from Django templates using JQuery. With the jQuery AJAX methods, you can request text, HTML, XML, or JSON from a remote server using both HTTP Get and HTTP Post and you can load the external data directly into the selected HTML elements of your web page. In this tutorial, we will learn how to make AJAX HTTP GET and POST requests from Django templates. Pre-Requirements I am assuming you have a basic working knowledge of Django. Therefore, I am not going into the project setup part in case you need help with that I recommend reading the following articles.

I spent this last week wrapping up the documentation and finishing up my final submission report for GSoC. I also discussed with my mentors the future steps we'll take with Mscolab. My code was just recently merged with the develop branch of MSS and all tests passed!. I am really excited to have users use a piece of software that I wrote. I am already planning on what I want to work on in MSS after GSoC is over as there is a lot I can learn while working on this project. These past 3 months have improved my coding skills significantly and introduced me to the amazing mentors at MSS. My time during GSoC has been absolutely wonderful and I can't wait to contribute to more interesting open source project. I hope next year, I would be able to mentor some bright students who are working on MSS .

Davy Wybiral: A Lesson in LoRa Module P2P Standards (or the Lack Thereof)
2020-08-31 15:03:33
I got a handful of LoRa modules from Reyax a while back, the RYLR896 model based on Semtech SX1276 chips. Instead of using an SPI interface they operate over UART using a small set of AT commands. This made them easier to work with since I didn't have to dig too deeply into a bunch of SPI registers and Semtech specs and they communicate between one another really well. My Espruino JS module for them is available here, which I've used in a few of my YouTube videos. And more recently I've written a MicroPython module for them here.

Reuven Lerner: New course: Testing your Python programs with pytest
2020-08-31 15:00:00
My first job was at a company that wrote software for hospitals. As you can imagine, our work needed to be really reliable — so we had an entire team dedicated to quality assurance (QA). Their job was to run our software for months at a time, given many different inputs, and to make sure that it didn’t cause trouble.  I can tell you that the head of QA was the most feared person in my department. And yet, we all knew that his job was of utmost importance. If it weren’t for him, buggy software could go out the door, with catastrophic effects for people being treated in hospitals around the world.More than 25 years have passed since I had that job. And while not every program directly affects people’s lives,  there’s no doubt that software is hugely influential. Buggy programs can not only hurt people, but lose money, destroy documents, give incorrect projections, and use up valuable resources.It’s no surprise, then, that testing continues to be really important. And while there are lots of  people still working in QA, much of that burden is now shouldered by individual developers, who have to test the code that they wrote themselves.  That’s right — you can test your own code, to make sure it does what it’s supposed to do (and  doesn’t do what it’s not supposed to do).Over the last few years, I’ve joined a large and growing number of Python developers using pytest — a test system written in Python, designed to be used by Python developers. And I have to say, pytest is truly amazing: It’s easy to learn, very powerful, and has a huge community that contributes a wide variety of plugins for everyone to use.Earlier this month, I asked subscribers to my “Better developers” list what topics they would like to learn in a series of live courses I’m starting to offer. And overwhelmingly, people wanted to learn pytest.I’m thus delighted to announce that on Sunday, September 13th, I’ll be teaching a live, four-hour online course about pytest: “Test your Python code with pytest” If you’ve always wanted to learn about testing in general, or pytest in particular, this course will jump-start you into understanding the hows (and whys) of testing your Python code.

Sumana Harihareswara - Cogito, Ergo Sumana: Apply For Grants To Fund Open Source Work, and Career Thoughts
2020-08-28 20:21:29
Apply For Grants To Fund Open Source Work When I tell people about grants they could get to help fund work on open source software projects, sometimes they are surprised because they didn't know such grants existed. Therefore, a month ago, I delivered a ten-minute PyOhio talk in which I shared: sample foundations and funders (such as Mozilla, the Chan Zuckerberg Initiative, NLNet, and Comcast) who want to fund open source software projects, and how much they're paying out a quick case study on how the Python Software Foundation got funding from Open Tech Fund to improve security, accessibility, and localization for PyPI key steps in figuring out a good project idea, budgeting, hiring, and submitting how the new Project Funding Working Group at the PSF can help you along the way I've now posted a transcript (with slides), and the ten-minute video is up. The Python context, and followup Q&A Have some additional thoughts and info I could not fit into the talk! Background and ideas: People who work on Python's packaging tools usually aren't paid to do so. It's usually but not always a side project. We have gotten grants (or similar funds) of $80,000 USD or $150K or $207K and they are a huge reason why we have the new PyPI (Warehouse) in production, instead of the legacy site have 2-factor auth on Warehouse are much closer to releasing the new pip dependency resolver On March 22, 2019, I started a wiki page to list some fundable projects in Python packaging. I figured that if we had a structured, public list of well-scoped, shovel-ready tasks that would move faster with funding, it would make it easier to find grants, sponsors, and other directed funds. And, heads-up, corporate readers: if you can help the PSF get some money to do these things, they are much more likely to happen, and Python will get much easier to deal with. We've now moved that list to GitHub. If you know that filling a particular gap would improve Python packaging and distribution, go ahead and make a pull request! And that doesn't just go for packaging. The Project Funding Working Group is seeking project ideas on a wider scale. If you make a well-structured list of fundable TODOs for your Python project, it can go in that list -- this will, in the future, make it easier for you to get funding. Eligibility and how the money flows: often, only public charities or similar institutions are eligible to apply for certain kinds of funds, which is why getting the Python Software Foundation involved is helpful -- they are often eligible to apply in cases where you as an individual are not eligible. The way we've been doing it for the past few years is: some volunteers research a grant opportunity and write a proposal (often with the assistance of a PSF staffer) and the Python Software Foundation submits it. If it gets funded, the PSF hires contractors to do the proposed work, and then those contractors perform the proposed work and (via the PSF) report back to the funder. I cofounded the new Project Funding Working Group to centralize those efforts, bring enthusiastic volunteers together, teach more people to do this stuff, and capitalize on the momentum of the last few years. We know some things about what some funders are seeking, and want to help match you up with funders who might be a good match. Depending on where you live, there may be country-specific grants that the existing members of the Project Funding Working Group know less about! Like, there is the Prototype Fund for people in Germany, and Innovation Fund Denmark, and there are a bunch of European Union grant opportunities that I know very little about like Horizon 2020. Erika Owens asked some followup questions: ...how to assess if a grant is worth applying for - how do you know the foundation is legit? how do you balance the amount of time proposing/reporting with the likely grant amount?.... also, from a documentation mindset—where can you go for help with this type of work? what public writing is useful to others? (and possible given so much secrecy with funding) Good questions. When is it worth applying? & more: Different projects need different amounts of money. A one-time gift of $10K (about 60-100 hours of work at USD$100-150/hour) is not enough to make a significant dent in some of the listed fundable packaging tasks, but $10K could support a "get the next release out and clean up docs/bugtracker/patch queue" effort for your favorite library. This is why the Project Funding Working Group is trying to amass informational resources (a list of funders, "how to write a proposal", etc.) and point a lot of people at those resources so many people can self-serve -- the volunteers in the Working Group do not have time to write a dozen grant proposals from scratch in a year, each of which is for $10-30K. It might take 10-20 hours to research and draft a multi-page grant proposal from scratch (it gets easier when you can copy and paste from previous proposals or planning documents for the same software project). Sometimes it takes longer if a bunch of stakeholders (such as project maintainers) have to agree on priorities and scope. I hope that the working group writes a few proposals each year and that they're for at least $80,000 each, and that we advise or otherwise help a bunch of other volunteers to write grants for varied amounts. Let's see how the first year goes. Maybe I'll be wildly off. I feel pretty lucky in that most of the grant-and-similar-funded projects I have worked on had fairly light reporting requirements, things that ended up taking maybe an hour per month plus maybe three hours at the end of the project. (Then again, I prep along the way by collecting meeting notes and updates on a public wiki page.) At the end of this year I need to make a fairly substantive report to the Chan Zuckerberg Initiative, so I may eat my words then! What public writing is useful to others? I see people sharing actual grant proposals and budgets, and the Project Funding WG will too (soon), and I think that helps a lot. I bet a before-and-after of a proposal before and after editing would also be helpful. Timelines like this slide here (from my PyOhio talk) help others set expectations for the process. Project retrospectives like this Read the Docs post -- ditto. Lists of funders including real talk about what they're looking for. Reminders of deadlines (like: apply for the Better Scientific Software Fellowship by September 30th). If you have more suggestions, please open an issue! How do you know whether the foundation is legit? Hmmm. I have confidence that I could tell whether a funder was fishy before getting into anything I'd regret, but I am having a hard time articulating the evaluation criteria I would use. Something to work on. And where can you go for help with this kind of work? I know I ought to learn more from the world of professional grantwriters and other nonprofit experts, like Candid, and perhaps I will have a spurt of energy sometime soon to go dive in. My career This week, on the way to posting this, I rearranged my conference talks page to be more navigable. I have given 35-50 talks on tech-related topics in the past 10 years, depending how you count. I used to talk a lot about Wikimedia, then about HTTP, then Python packaging and the plays. The response to my one talk about grants has already been strong and, if I just reacted to that, I'd give more talks about grants. Already my blog posts and talk about grants have led to Changeset Consulting client leads and some client work. And there's a logic here -- I have succeeded in doing something lucrative that other people would like to replicate. And it can be easy to get sucked into grantwriting (the work of researching and creating grant proposals), because I am clearly expert enough to be helpful, there are deadlines to motivate me and colleagues, and every available grant is an explicit invitation with a concrete amount of money attached. It's a trail others have already blazed. But grantwriting is a treadmill that ties projects to rich funders with short timescales, a topic ably covered by Nonprofit AF, The Revolution Will Not Be Funded: Beyond the Non-Profit Industrial Complex, and many others. As with recruiting, or diversity/equity/inclusion work, there's a lot of toil here. So, I am excited about the potential of the Project Funding WG, which will help many open source groups pursue not just grants but "external grants and similar funding." Including talking with companies who want to sponsor particular improvements, or generally sustain their dependencies (via Tidelift or a direct gift) and avoid the headache of forking or switching. And I'm open to Changeset Consulting doing some paid consulting work on grantwriting, and I'm doing some unpaid grantwriting to garner funding for projects where Changeset would do paid work. And I'm particularly interested in joining together with folks who are making big proposals to big foundation-style or government funders, upwards of USD$500K or in the millions. But, in the near future, I mostly want Changeset to work on paid projects, funded by for-profit companies, to rejuvenate and level up open source projects that they depend on but do not control. And that's looking promising. I'm using many of the same skills you use in grantwriting, because they're sales skills. And I am looking forward to blogging about one of these projects soon.

This week I started a new PR that adds multimethods for NumPy's random module. This continues the work started by one of my mentors by revising some multimethods and adding new ones as well as important classes like RandomState and Generator along with their methods. The multimethods added so far are manifold and so I won't extend the length of this blog post by enumerating them. You can however read the full list of multimethods in the PR link provided above. I also patched one ongoing PR that added multimethods for statistical functions by refactoring some default implementations. The defaults were redundantly using, in most but not all cases, a helper function for reducing the array argument's dimensions. This was brought to my attention by one of my mentors which resulted in a simple refactoring of the defaults.

What did I do last week? This last week of the coding phase, I went through the bug list that was made by mentors doing a thorough test and fixed them all. I improved the UI a little bit and added a "help" dialog for mscolab so new users can quickly get acquainted with all the features mscolab has to offer. After this I cleaned up the database setup script for mscolab and added database seed options. Now setting up mscolab is much easier than before and can work with multiple databases - sqlite, mysql, postgreSQL etc.  What will I do this week? Now all that's left is a little documentation fix and finishing up my report page for final GSoC submission. I can't believe how fast these 3 months went by and now I am in the final week of GSoC Did I get stuck anywhere? No.

2020-08-23 13:20:54
Today's tutorial will show you how to add and remove items between two QTreeWidgets. The source code is very simple to understand: the user interface is created with two QTreeWidgets. One is completed with elements and when the buttons are pressed, the elements are interchanged. import sys from PyQt5.QtWidgets import QApplication, QWidget, QDesktopWidget, QPushButton from PyQt5.QtWidgets import

Glyph Lefkowitz: Never Run ‘python’ In Your Downloads Folder
2020-08-23 06:47:00
One of the wonderful things about Python is the ease with which you can start writing a script - just drop some code into a .py file, and run python my_file.py. Similarly it’s easy to get started with modularity: split my_file.py into my_app.py and my_lib.py, and you can import my_lib from my_app.py and start organizing your code into modules.

2020-08-22 07:38:04
Last week, I finished finalizing the PR for the basic implementation of the H2ClientProtocol. The protocol now works with all the request methods except the CONNECT method. The work on Tunneling using CONNECT method is still in progress. I started with creating another protocol for negotiation which uses ALPN or NPN (whichever is available) to negotiate a protocol (presently one of HTTP/1.1 or HTTP/2) from the remote server based on the priority given by the user via the Scrapy project's settings and then uses the respective download handler to complete the request.

Quansight Labs Blog: Introducing Versioned HDF5
2020-08-21 13:00:00
The problem of storing and manipulating large amounts of data is a challenge in many scientific computing and industry applications. One of the standard data models for this is HDF5, an open technology that implements a hierarchical structure (similar to a file-system structure) for storing large amounts of possibly heterogeneous data within a single file. Data in an HDF5 file is organized into groups and datasets; you can think about these as the folders and files in your local file system, respectively. You can also optionally store metadata associated with each item in a file, which makes this a self-describing and powerful data storage model.

PyBites: There is More Than One Way to Solve a Bite Exercise
2020-08-21 08:37:00
According to the Zen of Python, "There should be one-- and preferably only one --obvious way to do it." It's a good principle for designing a program: the more ways there are of doing something, the more confusing the software becomes, along with a host of other problems. In reality, though, there almost always is more than one way to accomplish something. The quotation even displays this fact: it places the dash in two different ways, neither of which are the obvious way.

We worked to fix some of the issues that she found. The first issue that I tackled dealt with ambiguity about a course&rsquo;s relationship to a school year on the course&rsquo;s detail page. I fixed this issue by displaying the grade level on the course page to provide all the details.

Real Python: Data Version Control With Python and DVC
2020-08-19 14:00:00
Machine learning and data science come with a set of problems that are different from what you’ll find in traditional software engineering. Version control systems help developers manage changes to source code. But data version control, managing changes to models and datasets, isn’t so well established.

PSF GSoC students blogs: Week 11 Check-in
2020-08-19 13:58:31
This week's work was divided into two parts: fixing some issues in the backends and patching up older PRs. While working on the PR for indexing routines we noticed a bug in the backends that caused some classes to not be dispatched properly. What was happening was that all the classes added in the PR were calling NumPy classes regardless of the backend being used instead of calling the equivalent classes in the respective backends. This issue also touched on another problem that I encountered while preparing the new PR for the random module. The backends were also not dispatching the multimethods in modules correctly. This was apparent by the linalg module's tests which at the time were fixed to the NumPy backend. Because of this I created a new PR that fixed both of these issues and extended the linalg tests to other backends which allowed the PR for indexing routines to be patched and merged. I also worked on a previous PR that adds multimethods for statistical functions by adding default implementations to most of the reduction methods (e.g., median, mean, var).

Sebastian Witowski: Ask for Forgiveness or Look Before You Leap?
2020-08-19 00:00:00
“Ask for forgiveness” and “look before you leap” (sometimes also called “ask for permission”) are two opposite approaches to writing code. If you “look before you leap”, you first check if everything is set correctly, then you perform an action. For example, you want to read text from a file. What could go wrong with that? Well, the file might not be in the location where you expect it to be. So, you first check if the file exists:

Podcast.__init__: Building The Open Data Ecosystem For Music And More At Metabrainz
2020-08-17 21:32:07
The Musicbrainz project was an early entry in the movement to build an open data ecosystem. In recent years, the Metabrainz Foundation has fostered a growing ecosystem of projects to support the contribution of, and access to, metadata, listening habits, and review of music. The majority of those projects are written in Python, and in this episode Param Singh explains how they are built, how they fit together, and how they support the goals of the Metabrains Foundation. This was an interesting exporation of the work involved in building an ecosystem of open data, the challenges of making it sustainable, and the benefits of building for the long term rather than trying to achieve a quick win.

I have fixed most of them and it would take another day to fix all the remaining ones.

The Digital Cat: Delegation: composition and inheritance in object-oriented programming
2020-08-17 08:00:00
Object-oriented programming (OOP) is a methodology that was introduced in the 60s, though as for many other concepts related to programming languages it is difficult to give a proper date. While recent years have witnessed a second youth of functional languages, object-oriented is still a widespread paradigm among successful programming languages, and for good reasons. OOP is not the panacea for all the architectural problems in software development, but if used correctly can give a solid foundation to any system.

I started implementing the CONNECT method for Tunneling via HTTP/2. After a lot of testing, I realized the approach I was taking was not really feasible, hence next I plan to work on an approach which initially uses HTTP/1.1 CONNECT to establish a connection with the proxy and then shifts to HTTP/2 for all the requests made via proxy.

2020-08-10 14:00:00
After gaining some familiarity with Python, you may notice cases in which your functions don’t modify arguments in place as you might expect, especially if you’re familiar with other programming languages. Some languages handle function arguments as references to existing variables, which is known as pass by reference. Other languages handle them as independent values, an approach known as pass by value.

Hi everyone  a little late on this blog as I have to go back to college to get my stuff back. I passed the second evaluation, yay,. Till now I have been able to get the module metadata except the licenses. The licenses can be collected in 2 ways one is through making bash scripts to find and collect licenses from the module directory. Since licenses files dont have a set structure or a convention that's why its getting difficult and a foolproof  guarantee cant be given. Another way is through making an in house copyright to License parser. For debian licenses we have debut  used in tern I have to come up with similar kind of parser. I also have one idea of training a model from data collected by using github's api but thats just overkill.

However, the past few years there seems to have been a shift. I’m not sure if it’s just because Python has grown so much in popularity or if it’s something more basic, such as people becoming more sensitive about things. Whatever it is, the community seems to be heading away from what it once was.

For some reasons the tests throw an error randomly and sometimes they pass successfully. I suspect this is a timing issue but increasing sleep time in between commands did not fix this problem. My mentors and I are still investigating this issue. The next thing I worked on was import file and merge waypoints window. The import file functionality was simple to implement however, I have been a little stuck on the merge window implementation.  I am having some trouble to make the UI like I want with PyQt. I have gone through a lot of docs to see how to implement it in the most efficient and simpler way but have not found exactly what I am looking for. I am very close to finishing up all the work related to my proposal. With the merge window complete only some minor features would remain. After that I just need to finish up the remaining tests and fix bugs if any. So this week my aim is to finish this merge functionality and see how much else I can complete. I mostly get stuck while building the UI with PyQt5. There are some very simple tasks which would have been much easier in some other frameworks but I find them hard to do in PyQt. Although when I started GSoC I had absolutely zero experience in using PyQt, I am much more confident in using it now.

2020-07-28 14:00:00
If you have experience with other programming languages, like C or Java, then you’ve probably heard of the concept of null. Many languages use this to represent a pointer that doesn’t point to anything, to denote when a variable is empty, or to mark default parameters that you haven’t yet supplied. null is often defined to be 0 in those languages, but null in Python is different.

This was a great conversation about useful strategies for supporting new programmers in their efforts to learn a valuable skill.

I did add some BAM test files, added visualization function to NavMesh class similar to NavMeshBuilder class. So, now draw_nav_mesh_geom() in NavMesh class would work the same way as draw_poly_mesh_geom() in NavMeshBuilder class and can be accessed through even NavMeshNode class. BAM test files can be found in the Tests folder. A BAM object is created and read over in the test functions to test against the original values. So these were two main things I added in the previous week.  Along with them, I have started working on the documentation. It uses Sphinx's reStructured text (.rst) format. I have got familiar to it's coding / formatting styles. Also, I have added a new class NavMeshParams in the navigation library. So, the user can add custom vertices and faces to generate the navigation mesh without using the navmeshgen library. Or maybe, the user can get the navigation mesh generated using some other library and then write code to parse it into NavMesh class using NavMeshParams class.

I have been working on adding the tutorial on how to customise the HTML Reports. I have added a argument which will get the directory path from the user. I have also handled the hidden div problem from the plotly.js So now we don't need to reload the window on window resize. The performance has improved significantly for the reports.  

Matt Layman: Handle Default Values - Building SaaS #65
2020-07-23 00:00:00
In this episode, I updated a model to handle the default duration of new tasks. This default needed to come from the Course model instead of the CourseTask model so we had to determine how best to set that data in various forms. I also fixed some drop down selection bugs that populated a form with the wrong data. We made sure that all the code was well tested. I created a new default_task_duration field to the Course model.

Python is an intuitive and flexible language, but that versatility can also lead to problematic designs if you’re not careful. Nikita Sobolev is the CTO of Wemake Services where he works on open source projects that encourage clean coding practices and maintainable architectures. In this episode he discusses his work on the DRY Python set of libraries and how they provide an accessible interface to functional programming patterns while maintaining an idiomatic Python interface. He also shares the story behind the wemake Python styleguide plugin for Flake8 and the benefits of strict linting rules to engender good development habits. This was a great conversation about useful practices to build software that will be easy and fun to work on.

PSF GSoC students blogs: Blog post for week 7: Queue interface documentation
2020-07-20 15:27:53
Last week I was working on the specification of the queue interface. There are some important properties of how a queue is expected to behave so we thought it was worthwhile to document them. The documentation should make it easier for users to figure out how queues work (especially in the case of an error) but also make it easier in case a custom queue (facade) should be developed by a user of Scrapy.

PSF GSoC students blogs: GSoC Weekly Blog #4
2020-07-20 14:00:25
I spent the last week working mainly on search message and reply to a message functionality. The search message was a simple however, it took me quite some time to figure out how exactly I wanted to tackle the reply message functionality as there are multiple ways to do it. After completing these, I wrote some pending tests for file upload and then tests for search and reply. There were also some small bugs in the chat which I fixed. The PR is currently being reviewed by my mentors once it's merged my work for mscolab chat will be complete. I had a long conversation with my mentors about the next component that I'll be working on that is local editing of flightpaths in mscolab. I cleared all my doubts about the requirements and will start working on that this week. After some deeper understanding of the code, I have found out the version system would require much more work than I first thought so I'll be working on it when some of the local flight editing work is done because the version window is related to it a little bit. Last week I was stuck for a long time on a UI sizing issue with PyQT5 and have still not been able to fix it but I was able to put together a hack that works pretty well for now. If I get the time I'll tackle this issue later again and try to write a cleaner implementation.

The k-means clustering method is an unsupervised machine learning technique used to identify clusters of data objects in a dataset.

These traits make implementing k-means clustering in Python reasonably straightforward, even for novice programmers and data scientists.

Now user can specify these triage data and it will get reflected in the all machine readable output format. I have also added support for wheel and egg archive format. I have modernize error handling in outputengine and extractor. I have also fixed a bug which was causing progress bar to be displayed on quite mode. 

Brett Cannon: Unravelling attribute access in Python
2020-07-19 04:07:01
I wonder how many people realize that Python has a lot of syntactic sugar? I'm not claiming it's like a Lisp-based language where the syntax is as bare bones as possible (although the Lisp comparison is not entirely unfounded), but much of Python's syntax isn't technically needed as under the hood a good chunk of it is just function calls.

Podcast.__init__: The Past, Present, And Future Of The FLUFL: Barry Warsaw Shares His History With Python
2020-07-13 17:27:09
Barry Warsaw has been a member of the Python community since the very beginning. His contributions to the growth of the language and its ecosystem are innumerable and diverse, earning him the title of Friendly Language Uncle For Life. In this episode he reminisces on his experiences as a core developer, a member of the Python Steering Committee, and his roles at Canonical and LinkedIn supporting the use of Python at those companies. In order to know where you are going it is always important to understand where you have been and this was a great conversation to get a sense of the history of how Python has gotten to where it is today.

Real Python: Learn IP Address Concepts With Python's ipaddress Module
2020-07-13 14:00:00
Python’s ipaddress module is an underappreciated gem from the Python standard library. You don’t have to be a full-blown network engineer to have been exposed to IP addresses in the wild. IP addresses and networks are ubiquitous in software development and infrastructure. They underpin how computers, well, address each other.

PSF GSoC students blogs: Weekly Check-In #4 (5th Jul - 12th Jul)
2020-07-13 08:18:34
So we are about halfway through the project and the number-parser library is going strong. We are very close to publish version 1.0 to PyPI. What did you do this week ? The parser library was refactored to create a language class and use the language data python files. Tests were added for the supported language , which helped to identify a number of small bugs across the board, which were gradually fixed.  Did you get stuck anywhere ? One of the bugs was how to elegantly handle multiple consecutive multipliers for example 'thousand millions'. In the end I did come up with a reasonable solution that should be working across all languages but more tests would need to be added to ascertain this. What is coming up next ? This week the first version would be released , to do that would require a round of code-cleanup, adding documentation , and more tests for all supported languages.

Janusworx: A Hundred Days of Code, Day 002 - Basic Exercises
2020-07-09 13:45:05
Did a few exercises today. They were simple. Create a few classes, change them, modify them, use a list as an attribute and so on. In a couple of ways, this was just what I needed. One, I had an extremely busy day at work, and so I did not have the brain power to do anything complex, so I needed the bar really low any way. And two, I’ve realised, that I have always tried to just read a book and then leap mountains. I don’t know why. I must be a sucker for pain. And then when stuff does not work, I sulk and get frustrated. Easing into hard topics like this, makes it more enjoyable for me and I learn better. This is a meta skill, I should remember to use. Come to think of it, everything I have learnt recently, actually learnt, has been this way. I learnt Dvorak and touch typing, slowly, key by single key. I learnt to diet and lose weight, by tens of grammes in the beginning.

However, during all this time I’ve learned how documentation has a huge impact on the open-source community and I’ve been thankful to have been able to do this. But, from the beginning, I asked myself “why am I the ‘right person’ for this?”

There are primarily two query functions: findPath() and findStraightPath(). Both have their own uses. The implementation initially looked to be easy, but got real complex when I started coding. There were many other function calls I had to make in order to implement these two functions, and in process taking care of the variables involved.

Mistakes in your code are known as “bugs”. You will make mistakes. You will make many mistakes, and that’s totally fine. Most of the time, they will be simple mistakes such as typos. But since computers are very literal, even typos prevent your code from working as intended. So they need to be fixed. The process of fixing your mistakes in programming is known as debugging.

So this week I had my first evaluation. It went great also I received my stipend today so hurray.Extracting golang metadata with shell is frustrating not every go lang module have licenses or the copyright text in a set format. So writing a generic script is quiet challenging I researched on how go license works turns out they have a dedicated license parser as well as scripts which can request license from github. But we can't do that. This week was mostly debugging and restarting again. Now I am trying to work on go.sum file. Extracting names and versions is easy. So all the go modules live in ~/go/pkg/mod and then repo name. But we can't cd into module dir with its name because some does which have upper case letter in their name have different directory name. My exams are also nearing so I have to study for that too . :P

Podcast.__init__: Pure Python Configuration Management With PyInfra
2020-07-06 17:56:25
Building and managing servers is a challenging task. Configuration management tools provide a framework for handling the various tasks involved, but many of them require learning a specific syntax and toolchain. PyInfra is a configuration management framework that embraces the familiarity of Pure Python, allowing you to build your own integrations easily and package it all up using the same tools that you rely on for your applications. In this episode Nick Barrett explains why he built it, how it is implemented, and the ways that you can start using it today. He also shares his vision for the future of the project and you can get involved. If you are tired of writing mountains of YAML to set up your servers then give PyInfra a try today.

Hi!

PSF GSoC students blogs: GSoC: Week 6: class InputEngine
2020-07-06 07:12:24
I have started working on input engine this week. Currently, we only have csv2cve which accepts csv file of vendor, product and version as input and produces list of CVEs as output. Currently, csv2cve is separate module with separate command line entry point. I have created a module called input_engine that can process data from any input format (currently csv and json).User can now add remarks field in csv or json which can have any value from following values ( Here, values in parenthesis are aliases for that specific type. )

Hello everyone,

Quansight Labs Blog: Creating a Portable Python Environment from Imports
2020-06-30 19:39:56
Python environments provide sandboxes in which packages can be added. Conda helps us deal with the requirements and dependencies of those packages. Occasionally we find ourselves working in a constrained remote machine which can make development challenging. Suppose we wanted to take our exact dev environment on the remote machine and recreate it on our local machine. While conda relieves the package dependency challenge, it can be hard to reproduce the exact same environment.

Podcast.__init__: Build Your Own Domain Specific Language in Python With textX
2020-06-30 00:25:02
Programming languages are a powerful tool and can be used to create all manner of applications, however sometimes their syntax is more cumbersome than necessary. For some industries or subject areas there is already an agreed upon set of concepts that can be used to express your logic. For those cases you can create a Domain Specific Language, or DSL to make it easier to write programs that can express the necessary logic with a custom syntax. In this episode Igor Dejanović shares his work on textX and how you can use it to build your own DSLs with Python. He explains his motivations for creating it, how it compares to other tools in the Python ecosystem for building parsers, and how you can use it to build your own custom languages.

I have finished my work on improving cvedb this week. I am using aiohttp to download NVD dataset instead of requesting with  multiprocessing pool. This has improved our downloading speed since now every tasks are downloading concurrently in same thread instead of 4 tasks at a time with process pool. I have also measured performance of aiosqlite but it was significantly slower while writing to database so, I decided to keep writing process synchronous. I have also added a beautiful progressbar with the help of rich module. So, now user can get feedback about progress of the downloading and updating database.  Here is the demo of how does it look now.

PSF GSoC students blogs: GSoC Week 5: Priority Matters
2020-06-29 15:36:32
Instead of working on HTML output tests I worked on normalizing the package name and the module name because they were creating confusion so I prioritized that. I also added Vendor field in Console, CSV and JSON. So now we'll get output as Vendor, Product, Version, CVE Number, Severity. That will help distinguish between products that have same name but different vendors. Also I found that our console output is failing on windows, thanks to Niraj-Kamdar who was working on improving windows tests. So I also fixed that issue but as the issue was related to rich so I contacted the developer of rich because this issue can be faced by others. So he worked and released rich version 3.0.0 which he thinks can solve our error. Though I have not tested that But I think that will solve our problem in a very efficient way. Thanks to the developer of rich.

2020-06-26 05:31:53
So with the code-context, the dictation in Listener is getting okay-ish. It's still pretty frustrating and error prone, but I can use it maybe 1/4 of the time (mostly for doc-strings). Part of the frustration is just that the language models are not yet well tuned for some commonly needed phrases that the tokeniser didn't generate for the code corpus, but a big part of it is that I don't yet have the correction/undo operations nor the navigation bits, so any mistake means editing by keyboard. The lack of a good contextual awareness/biasing model is also pretty big.

At this point aldryn_categories and aldryn_people have both needed to be pulled into the repository tree since they're also abandoned projects that were abandoned prior to upgrading for Django 3 (though the actually changes needed in them was minimal, they won't work as-is with Django 3).

2020-06-23 01:10:34
Once you release an application into production it can be difficult to understand all of the ways that it is interacting with the systems that it integrates with. The OpenTracing project and its accompanying ecosystem of technologies aims to make observability of your systems more accessible. In this episode Austin Parker and Alex Boten explain how the correlation of tracing and metrics collection improves visibility of how your software is behaving, how you can use the Python SDK to automatically instrument your applications, and their vision for the future of observability as the OpenTelemetry standard gains broader adoption.

This week I finished up all the tests required in admin window as well as added markdown support in mscolab chat. I also did some redesigning of the chat window. I also made a new window to show the history of all the changes for mscolab. Most of my time last week was spent on how to implement the markdown feature. I looked at various different ways of implementing it. I was able to create rich text editor buttons for common features like bold, italics, underline and lists. However, I ran into a big issue which was that PyQt's QTextEdit widget returned a massive HTML response even for a very small message. I didn't want to store such a huge response in the database as it contained several unwanted HTML tags and inline styles. I could not find a way to reduce this output so I had to completely change my approach. I completely scrapped the button approach and moved on to allowing markdown syntax in the chat itself. I used the python-markdown library for converting markdown to HTML on the fly. I had to spend some time figuring out how to deregister any syntax I don't want to support as I only wanted support for bold, italics and lists. After going through the library's documentation and tutorials, I was able to get it all working🥳 After adding the markdown support, I removed some existing code which was made redundant after the addition of the admin dashboard and fixed the tests which were affected by this code. This week, I would be working on adding other chat features like edit and delete messages and hopefully, if I am able to complete these features move on to finishing up the new change history window.

PSF GSoC students blogs: Weekly Blog #2 ( 15th June - 22nd June)
2020-06-21 19:23:19
Hi all , so we have had 3 weeks of coding till now and overall am pleased with the progress of the project. It has been going smoothly without too many major issues. The three major milestones achieved this week were :- 1. Created a draft PR for incorporation with date-parser. The number-parser library is constantly improving but one of the major goals was also to incorporate it with other Scrapy libraries (primarily date-parser and price-parser). The incorporation needed to be seamless without too much modification to the date-parser base code. Once number-parser library improves we can add it as a dependency. 2. Issue creation and resolution on the number-parser library. Since we are done with the MVP , we can now move to a more organized structure where we are now discussing bugs/features and I am able to create PRs to target specific issues. 3. Implemented a parse_number feature that allows to parse single numbers written in natural language. eg) 'fifty seven' -> 57 , 'cats' -> None The plan for  next-week is to tackle the multi-language feature (starting with spanish,hindi,russian) and hopefully by the end of the week will have the pipeline to incorporate multiple languages in place.

2020-06-16 14:00:00
Have you ever had to work with a dataset so large that it overwhelmed your machine’s memory? Or maybe you have a complex function that needs to maintain an internal state every time it’s called, but the function is too small to justify creating its own class. In these cases and more, generators and the Python yield statement are here to help.

PyCharm: Tutorial: Visual testing with pytest
2020-06-15 16:39:16
If you are like many Python developers out there you LOVE writing code! Tests? Not so much. Whether it’s the concept of testing or the interface of testing tools, testing is a chasm not all developers cross. The Visual Testing with pytest tutorial aims to bring Python testing to the masses, taking a new approach to first contact with Python testing.

2020-06-15 13:23:41
We, PyLadies, have started our journey for quite a sometime now. Every year since 2016, we are growing in numbers and chapters. Currently, we have eight active chapters and counting. The COVID pandemic has somehow stopped our course of having physical meetups. But on a brighter note, the situation has opened up a new opportunity for us—the chance to be united. Therefore we, the PyLadies groups in India, have decided that we are going to have one collective meetup every month.

2020-06-15 13:11:03
Last week I discussed that we need to find another charting library because "Pygal" was not up to the mark. So I started looking and found that Plotly can be an option. So I tested if it can produce the same results as Pygal and found it is much more useful. I'm now using Plotly Python which is a Plotly API. So, now we can quickly generate graphs using Plotly. I was also working on adding Filter property so that the user can filter out products. Now we can generate HTML reports with a nice filter property.

Podcast.__init__: Build A Personal Knowledge Store With Topic Modeling In Contextualize
2020-06-15 12:53:53
Our thought patterns are rarely linear or hierarchical, instead following threads of related topics in unpredictable directions. Topic modeling is an approach to knowledge management which allows for forming a graph of associations to make capturing and organizing your thoughts more natural. In this episode Brett Kromkamp shares his work on the Contextualize project and how you can use it for building your own topic models. He explains why he wrote a new topic modeling engine, how it is architected, and how it compares to other systems for organizing information. Once you are done listening you can take Contextualize for a test run for free with his hosted instance.

Hey back with the second check in blog covering week 2. What did you do this week ? Fixes and features - still tweaking the number parser library now it handles multiple numbers (not separated by a delimiter and returns a set of words as opposed to a single word). I also experimented with the date-parser library and looked into the integration. Did you get stuck anywhere ? Nothing major as such . I was modifying, updating the overall structure of the library , which needed some research into best python practices. What is coming up next ? The next week involves completing the integration with date-parser and price-parser. Additionally hoping to handle date-specific years.

An important concept for proficient users of these two libraries to understand is how data are referenced as shallow copies (views) and deep copies (or just copies). Pandas sometimes issues a SettingWithCopyWarning to warn the user of a potentially inappropriate use of views and copies.

Python prints a traceback when an exception is raised in your code. The traceback output can be a bit overwhelming if you’re seeing it for the first time or you don’t know what it’s telling you. But the Python traceback has a wealth of information that can help you diagnose and fix the reason for the exception being raised in your code. Understanding what information a Python traceback provides is vital to becoming a better Python programmer.

Scrapy uses queues for handling requests. The scheduler pushes requests to the queue and pops them from the queue when the next request is ready to be made. At the moment, there is no support for external message queues (e.g. Redis, Kafka, etc.) implemented in Scrapy, however, there are external libraries (https://github.com/rmax/scrapy-redis and others) that bridge Scrapy with external message queues.

PSF GSoC students blogs: GSoC 2020 Blog Post (#1)
2020-06-08 02:35:56
Hello all! The coding period officially started last week and me and my partner Aditya Sharma began working on our project. Like I said earlier I was working on the Authentication module and that’s what I did. A design (which was created in AdobeXD) of what the expected end product should look like was given to me, which I used as a reference while writing the React code.  I started with setting up a React application using the "create-react-app" bootstrap method. This was followed by adding a bunch of dependencies ranging from router requirements, axios method for backend communication, linting and formatting checkers etc. My partner had done this previously so he helped me in setting up all of these. Once the directory structure was set up I began working on the authentication module. As I mentioned in my last blog post I started working on the Authentication module in the community bonding period itself, so I had a basic version of the module ready. Main thing that I had to do now was to make the interface look like the one I received as a part of the design. This involved writing SASS (which is basically like CSS) for the different pages and components. I also spent a lot of time on making sure that my UI was responsive and adaptable on different screen sizes. I submitted a PR for the same which is currently being reviewed. Mentors have been very helpful and quick in their response towards my work. Their comments on the PR are insightful and I am working on resolving the issues pointed out by them.

Hi,

Podcast.__init__: Extending The Life Of Python 2 Projects With Tauthon
2020-06-02 01:49:53
The divide between Python 2 and 3 lasted a long time, and in recent years all of the new features were added to version 3. To help bridge the gap and extend the viability of version 2 Naftali Harris created Tauthon, a fork of Python 2 that backports features from Python 3. In this episode he explains his motivation for creating it, the process of maintaining it and backporting features, and the ways that it is being used by developers who are unable to make the leap. This was an interesting look at how things might have been if the elusive Python 2.8 had been created as a more gentle transition.

Hey, I'm Tanish Grover. I'll be contributing to Mission Support System (MSS) under Python Software Foundation during GSoC'20. I'll be working on improving Mscolab functionalities. What did you do this week? I spent the last week of community bonding closing some existing issues in Mscolab to get more familiarized with the codebase. I spent some time reading the PyQt5 documentation and learning how to write better tests. I started designing the admin window and have got a good understanding of exactly what part of the existing codebase I need to update and what I need to add so I would be more efficient when I start coding. What is coming up next? This week I would be working on the Mscolab admin dashboard. I would be completing the UI and adding the add/modify/delete functionality. Did you get stuck anywhere? I got stuck while fixing an issue which required to import a different file when the test suites are running but I was able to fix it.

Brett Cannon: The many ways to pass code to Python from the terminal
2020-05-29 22:44:25
For the Python extension for VS Code, I wrote a simple script for generating our changelog (think Towncrier, but simpler, Markdown-specific, and tailored to our needs). As part of our release process we have a step where you are supposed to run python news which points Python at the news directory in our repository. A co-worker the other day asked how that worked since everyone on my team knows to use -m (see my post on using -m with pip as to why)? That made me realize that other people probably don't know the myriad of ways you can point python at code to execute, hence this blog post.

I had an onboarding meeting with my mentors where we got to know each other a bit better. They advised me to play around with uarray and unumpy without any goal in mind which I found to be a very good advice. I played a bit with special methods by implementing a simple Vector2D class and used the code in this notebook with some print statements to understand better the protocols and how they are called. I wanted to start earlier on my project so I took over a PR from one of my mentors which adds multimethods for the linalg module.

Podcast.__init__: Dependency Management Improvements In Pip's Resolver
2020-05-25 23:32:12
Dependency management in Python has taken a long and winding path, which has led to the current dominance of Pip. One of the remaining shortcomings is the lack of a robust mechanism for resolving the package and version constraints that are necessary to produce a working system. Thankfully, the Python Software Foundation has funded an effort to upgrade the dependency resolution algorithm and user experience of Pip. In this episode the engineers working on these improvements, Pradyun Gedam, Tzu-Ping Chung, and Paul Moore, discuss the history of Pip, the challenges of dependency management in Python, and the benefits that surrounding projects will gain from a more robust resolution algorithm. This is an exciting development for the Python ecosystem, so listen now and then provide feedback on how the new resolver is working for you.

PyCharm: Interview: PyCharm helping developers to navigate complexity and be more productive
2020-05-11 10:04:56
Developing in Python is the dream job of many developers out there. According to the latest survey from StackOverflow, Python is the second most ‘loved’ language, and the ‘most wanted’ one. Now, imagine working for a Python software house where you have the opportunity to be part of many different projects, sometimes even simultaneously? It sounds amazing, right? But, of course, it also brings some challenges. You need to communicate more, be aware of different project scopes, take decisions under different technology requirements, and much more. Complexity is also closely related to productivity. While some people excel in this scenario others spend more time finding their way around.

Abhijeet Pal: How To Upload Images With Django
2020-05-10 15:55:12
One of the most common requirement in any modern web application is the ability to take images or pictures from the users as input and save them on the server however Letting users upload files can have big security implications. In this article, we will learn how to upload images in a Django application. Uploading Images in Django Django has two model fields that allow user uploads FileField and ImageField basically ImageField is a specialized version of  FileField that uses Pillow to confirm that a file is an image. Let’s, start by creating models. models.py from django.db import models class Image(models.Model): title = models.CharField(max_length=200) image = models.ImageField(upload_to='images') def __str__(self): return self.title The image column is an ImageField field that works with the Django’s file storage API, which provides a way to store and retrieve files, as well as read and write them. The upload_to parameters specify the location where images will be stored which for this model is MEDIA_ROOT/images/ Setting dynamic paths for the pictures is also possible. image = models.ImageField(upload_to='users/%Y/%m/%d/', blank=True) This will store the images in date archives …

Despite how much I like using python in Jupyter notebooks, I do wish for the editor capabilities you can find in VS Code. I also would like my files to work better when versioning them with git.

Podcast.__init__: Maintainable Infrastructure As Code In Pure Python With Pulumi
2020-05-04 12:04:59
After you write your application, you need a way to make it available to your users. These days, that usually means deploying it to a cloud provider, whether that’s a virtual server, a serverless platform, or a Kubernetes cluster. To manage the increasingly dynamic and flexible options for running software in production, we have turned to building infrastructure as code. Pulumi is an open source framework that lets you use your favorite language to build scalable and maintainable systems out of cloud infrastructure. In this episode Luke Hoban, CTO of Pulumi, explains how it differs from other frameworks for interacting with infrastructure platforms, the benefits of using a full programming language for treating infrastructure as code, and how you can get started with it today. If you are getting frustrated with switching contexts when working between the application you are building and the systems that it runs on, then listen now and then give Pulumi a try.

Łukasz has created a talk for PyCon 2020 about using AsyncIO with Music. In this talk he shows live examples of coroutines, gathering, the event loop and events being triggered to create a piece of music. They talk about his role as the release manager for Python 3.8 and 3.9. He also provides background on the origins of his very popular, uncompromising code formatter, Black, and the types of problems it can solve inside of an organization. Łukasz previously worked for Facebook, which is where he started Black. He talks about recently moving back to Poland. Łukasz discusses his current work for Edge DB, building a new generation object-relational database.

BreadcrumbsCollector: @staticmethod considered a code smell

Python offers quite a few built-in decorators that can be used to give methods of classes certain superpowers. @property turning method into a read-only field-like attribute is a classic example. Or @classmethod – a method that receives a class as a first argument, not an instance. Fun fact, this kind of method is usually called static method in other languages (e.g. Java, C#, C++ just to name a few).

Python Software Foundation: The path forward for typing - Python Language Summit 2020
2020-04-30 22:37:15
"There are a lot of PEPs about typing!" said Guido van Rossum at the Language Summit. Since 2014 there have been ten PEPs approved for Python's type-checking features. Two of them have been approved already this year: the relatively "esoteric" PEP 613: Explicit Type Aliases, and another that will have widespread impact, PEP 585: Type Hinting Generics In Standard Collections, written by Łukasz Langa and mainly implemented by Van Rossum. Thanks to this PEP, types which had been defined like List[int] can now be spelled list[int], with a lowercase "L". As Van Rossum told the Python Language Summit, "We want to avoid a world where users have to remember, 'Here I have to use a capital-L List and here I use a lowercase-L list.'"

But the environment is changing: Python's BDFL has retired, and Python's user base is expanding, becoming more global, and moving away (to some degree) from lower-level programming to higher-level applications. These changes impose new documentation burdens on the small core team. Willing said, "We don't scale well."

Having just recently experienced a period of burnout, I would like to share some ideas that might help you skirt by it in your own life. And, before I go on, let me say loud and clear, there is absolutely no shame in experiencing, or reaching out for help from, anxiety, fear, anger, burnout, depression, or any other mental condition. If you think you might be struggling with something, please reach out for help! You might have to reach out several times to multiple sources, but remember you are too valuable to waste time with this funk.

Real Python: Structuring a Python Application
2020-04-28 14:00:00
Python, though opinionated on syntax and style, is surprisingly flexible when it comes to structuring your applications. On the one hand, this flexibility is great: it allows different use cases to use structures that are necessary for those use cases. On the other hand, though, it can be very confusing to the new developer. The Internet isn’t a lot of help either. There are as many opinions as there are Python blogs!

Anarcat: Drowned my camera: dealing with liquid spills in electronics
2020-04-28 13:46:19
Folks who acutely dig into this website might know that I have been taking more pictures recently, as I got a new camera since January 2018: a beautiful Fujifilm X-T2 that I really like. Recently, I went out on a photo shoot in the rain. It was intermittent, light rain when I left so I figured the "weather proofing" (dpreview.com calls this "environmentally sealed") would keep the camera secure. After an hour of walking outside, however, rain intensified and I was just quickly becoming more and more soaked. Still trusting the camera would function, I carried on. But after about 90 minutes of dutiful work, the camera just turned off and wouldn't power back on.

Abhijeet Pal: Using Environment Variables In Django
2020-04-26 14:21:52
While working with web applications often we need to store sensitive data for authentication of different modules such as database credentials and API keys. These sensitive keys should not be hardcoded in the settings.py file instead they should be loaded with Environment variables on runtime. An environment variable is a variable whose value is set outside the program, typically through a functionality built into the operating system. An environment variable is made up of a name/value pair. Environment variables help us keep secrets (for example, Passwords, API tokens, and so on) out of version control, therefore, they are considered an integral part of the popular Twelve-Factor App Design methodology and a Django best practice because they allow a greater level of security and simpler local/production configurations. Also, environment variables provide a greater degree of flexibility for switching between local development setup and production setup. Therefore Adding environment variables is a necessary step for any truly professional Django project. Creating Environment Variables Create a .env file in the same directory where settings.py resides and add the following key-value pair inside the …

John Cook: A spring, a rubber band, and chaos
2020-04-26 12:39:36
Suppose you have a mass suspended by the combination of a spring and a rubber band. A spring resists being compressed but a rubber band does not. So the rubber band resists motion as the mass moves down but not as it moves up. In [1] the authors use this situation to motivate the following differential equation:

Abhijeet Pal: How To Deploy Django App with Nginx, Gunicorn, PostgreSQL and Let’s Encrypt SSL on Ubuntu
2020-04-26 10:03:54
Django is a high-level full-stack open-source web framework written in Python, that encourages rapid development and clean, pragmatic design. Django is the go-to framework for any project irrespective of size, from a basic blog to a full-fledged social media app. Out of the box, Django comes with a built-in development server that is used locally. However, it isn’t suitable for the production environment because it’s single-threaded and lacks security measures. In this article, we will learn how to deploy a Django application with Nginx, Gunicorn, PostgreSQL, and Let’s Encrypt SSL on an Ubuntu server. Production Stack Architecture A modern Django application’s production stack is built with the following components. OS – Ubuntu WSGI Server – Gunicorn Web Server – Nginx Database – PostgreSQL The following diagram illustrates how Django works in the production environment. The following will happen when the client browser launches an HTTP request NGINX receives the HTTP request. If a static file is requested, NGINX serves the static file directly. If a dynamic page is requested, NGINX delegates the request to Gunicorn through a UNIX socket. Gunicorn …

Kushal Das: mod_wsgi and a Python extention
2020-04-23 06:40:13
I was working on a performance analysis of a web API. After I identified the possible issues, I tried to see if I can use a native extension for that part of code (it is a Flask application). In this case the extension was written in Rust. It worked very well. In both test environment and using mod_wsgi-express it was super fast. But it failed when I tried to use it in the production under nginx + mod_wsgi combination. The import modulename statement was just stuck. Causing a timeout in the application. There were no other error messages or log lines.

Peer authentication failed error arrives when you try to login to your PostgreSQL user but authentication fails because by default psql connects over UNIX sockets using peer authentication instead of password authentication. In this article we will learn how to get rid of FATAL: Peer authentication failed for user “postgres” error by enforcing password authentication over Unix sockets peer method, First, navigate to the /etc/postgresql/10/main directory. cd /etc/postgresql/10/main Note that 10 is the PostgreSQL version it can be different for you. Here resides the pg_hba.conffile we need to do some changes here you may need sudo access for this. sudo nano pg_hba.conf Scroll down the file till you find this – # Database administrative login by Unix domain socket local all postgres peer Here change the peer to md5 as follows. # Database administrative login by Unix domain socket local all postgres md5 peer means it will trust the authenticity of UNIX user hence does not prompt for the password. md5 means it will always ask for a password, and validate it after hashing with MD5. Now save the file and restart the Postgres server. …

Sumana Harihareswara - Cogito, Ergo Sumana: Persisting
2020-04-21 16:19:04
I've now sewn three fabric facemasks. For fabric I used old tech company tee shirts. For ties: elastic from free airline eyemasks, shoelace-like handles from fancy shopping bags, and the hemmed bits of the tee shirts. All of them are serviceable. I'll be trying to improve and, if I can get better, give some away. We used this approach to gather and grow yeast using raisins, sugar, and water in a jar on a windowsill. Today Leonard's using it to make bread. We have some powdered dried yeast but are trying to save it. And we've been growing green onions in some jars of water on another windowsill. Their stalks keep pushing out new green growth. The most successful watercolor painting I've done so far is a portrayal of one of those bunches. The pip 20.1b1 beta release is out. And Python 2.7.18 is out marking the very last, final, release of Python 2.7 and the end of the 2.x era. My household contributed to both of these things. Here's Leonard's pull request that adds an informational banner to the 2.7 docs. When I can concentrate on work or exercise or media it's better. The news is awful. I try to only listen to or look at it a few minutes per day. There is light through the windows, along with the rain and lightning, and I see the tree branches in the wind, falling and rising, falling and rising. Every night at 7pm I know it's 7 because people start clapping and ringing bells from our windows and balconies, a gesture of support for the health care workers and all the other essential workers who are trying to keep us all going. I do it too. The other night I got out a little temple bell and started using that. Someone has a tambourine. A few nights ago someone started chanting "USA! USA!" and I recoiled; as I joked to a few friends, better to chant "South! Korea!" or "Germany!" since they're actually doing it right. And someone else has, a few times, played a recording of "The Star-Spangled Banner". As I mentioned to friends: well, the thing that works about that song now is that it's a question. Does that banner still wave? We don't know! I also have joked: And is this the land of the brave and the home of the free, or the land of the scared and the home of the at home? But it's all those things, of course. And the rhetoric of that joke, as though you cannot be both at home and free, plays into the hands of foolish, even malicious shouters who prefer to swan around shedding and catching viruses, and to mob streets while braying about government restrictions, and refuse to love their neighbors. I'm glad of the rain. It feels natural to be inside when it's raining.

BreadcrumbsCollector: How to patch in Python?
2020-04-20 08:00:00
(monkey-) patching is a technique for changing code behaviour without altering its source. It is done in runtime, usually by overriding attributes of existing objects. An object can be an instance of some sort, a class or even a module. The technique is most commonly (ab)used for tests when we cannot pass mocks in a simple way.

Quansight Labs Blog: Introducing ndindex, a Python library for manipulating indices of ndarrays
2020-04-20 05:00:00
One of the most important features of NumPy arrays is their indexing semantics. By "indexing" I mean anything that happens inside square brackets, for example, a[4::-1, 0, ..., [0, 1], np.newaxis]. NumPy's index semantics are very expressive and powerful, and this is one of the reasons the library is so popular.

IslandT: Count and Index method in Python Tuple
2020-04-20 04:52:36
Tuple just likes list, is an object used to group together related data in python. The difference between tuple and list is that the data inside tuple cannot be changed whereas the data in the list can be changed after that list object has been declared.

The Three of Wands: Building Pyrseia I: The Idea
2020-04-19 14:58:16
Over at Highrise, we're looking to replace our internal Python RPC library. The in-house solution we're using now isn't particularly bad, but it doesn't integrate well with Mypy, which is a Python typechecker that might be useful to us. It's also somewhat boilerplate-y, and very coupled to our particular set of design choices. This series of articles follows my attempts to do better, in the form of a modern, open source, fully customizable RPC library. I've decided to call the library Pyrseia, which is an ancient greek method of long distance communication. I've created the initial repository over at GitHub.

BreadcrumbsCollector: Beware of chicken testing! (or mocks overuse)
2020-04-17 14:00:00
Dealing with problematic dependencies is an indispensable part of software testing. Often, we cannot or do not want to rely on 3rd party service/network communication/hard drive etc., especially in unit-tests. The reasons vary; external dependencies are usually slow, fallible and difficult to put into the expected state before the actual test. Consider the following code snippet (simplified – no logger, no saving to database etc):

Mike Driscoll: An Overview of Profiling Tools for Python
2020-04-14 05:05:20
What does it mean to profile ones code? The main idea behind benchmarking or profiling is to figure out how fast your code executes and where the bottlenecks are. The main reason to do this sort of thing is for optimization. You will run into situations where you need your code to run faster because your business needs have changed. When this happens, you will need to figure out which parts of your code are slowing it down.

This can be useful in HTTP clients that need to make several requests before they have all the information they need.

Podcast.__init__: Distributed Computing In Python Made Easy With Ray
2020-04-14 01:35:42
Distributed computing is a powerful tool for increasing the speed and performance of your applications, but it is also a complex and difficult undertaking. While performing research for his PhD, Robert Nishihara ran up against this reality. Rather than cobbling together another single purpose system, he built what ultimately became Ray to make scaling Python projects to multiple cores and across machines easy. In this episode he explains how Ray allows you to scale your code easily, how to use it in your own projects, and his ambitions to power the next wave of distributed systems at Anyscale. If you are running into scaling limitations in your Python projects for machine learning, scientific computing, or anything else, then give this a listen and then try it out!

Anwesha Das: Internet Shutdown Panel at NullCon, 2020
2020-04-13 19:42:55
Internet shutdown has become a pretty regular event in today’s world. India has seen the most number of shutdowns. Internet shutdowns are the “intentional disruption” of wired connection or mobile internet and /or both. Primarily carried on by the Government authorities with the aim of controlling the communication and the flow of information accessible over internet. The shutdowns vary in time, period, place, area and duration. Since the internet has become an essential to our physical world. It is critical for smooth working of every infrastructure. From health care to transportation, banking to business to Government Administration. Any and every form of internet shutdown not only slams the internet but disrupts the daily life of every individual. At NULLCON 2020 we, HasGeek, as a part of RootConf initiative, organized a panel on “Anatomy of Internet Shutdowns”. It was organized as a part of Media Track at NullCon. There were few core questions to which we were trying to find answers through this panel.

The Digital Cat: Multiple inheritance and mixin classes in Python
2020-04-08 10:47:24
I recently revisited three old posts on Django class-based views that I wrote for this blog, updating them to Django 3.0 (you can find them here) and noticed once again that the code base uses mixin classes to increase code reuse. I also realised that mixins are not very popular in Python, so I decided to explore them, brushing up my knowledge of the OOP theory in the meanwhile.

Podcast.__init__: Building The Seq Language For Bioinformatics
2020-04-07 01:35:38
Bioinformatics is a complex and computationally demanding domain. The intuitive syntax of Python and extensive set of libraries make it a great language for bioinformatics projects, but it is hampered by the need for computational efficiency. Ariya Shajii created the Seq language to bridge the divide between the performance of languages like C and C++ and the ecosystem of Python with built-in support for commonly used genomics algorithms. In this episode he describes his motivation for creating a new language, how it is implemented, and how it is being used in the life sciences. If you are interested in experimenting with sequencing data then give this a listen and then give Seq a try!

BreadcrumbsCollector: When to use the Clean Architecture?
2020-04-03 08:00:00
There are few possible reactions after learning about the Clean Architecture or Hexagonal Architecture (AKA Ports & Adapters) or even merely innocent service layer in Django. Some developers are enthusiastic and try to apply these techniques immediately, some are hesitant, full of doubts. The rest is strongly opposing, declaring openly this is an abomination. Then they say we already have excellent tools, like Django. Then they argue others don’t know about the advanced features of common tools. Then they call you Java developer in disguise.

Brett Cannon: What the heck is pyproject.toml?
2020-04-01 04:25:32
Recently on Twitter there was a maintainer of a Python project who had a couple of bugs filed against their project due to builds failing (this particular project doesn't provide wheels, only sdists). Eventually it came out that the project was using a pyproject.toml file because that's how you configure Black and not for any other purpose. This isn't the first time I have seen setuptools users use pyproject.toml because they were "told to by <insert name of tool>" without knowing the entire point behind the file. And so I decided to write this blog post to try and explain to setuptools users why pyproject.toml exists and what it does as it's the future of packaging in the Python ecosystem (if you are not a conda user 😉).

Real Python: Comparing Python Objects the Right Way: "is" vs "=="
2020-03-31 14:00:00
There’s a subtle difference between the Python identity operator (is) and the equality operator (==). Your code can run fine when you use the Python is operator to compare numbers, until it suddenly doesn’t. You might have heard somewhere that the Python is operator is faster than the == operator, or you may feel that it looks more Pythonic. However, it’s crucial to keep in mind that these operators don’t behave quite the same.

2020-03-30 12:55:00

In May 2019, Microsoft announced the release of WSL 2 which includes an updated architecture that improved many aspects of WSL - especially file system performance. I have been following WSL for a while but now that WSL 2 is nearing general release, I decided to install it and try it out. In the few days I have been using it, I have really enjoyed the experience. The combo of using Windows 10 and a full Linux distro like Ubuntu is a really powerful development solution that works surprisingly well.

2020-03-30 12:00:00
Mock is a category of so-called test doubles – objects that mimic the behaviour of other objects. They are meant to be used in tests to replace real implementation that for some reason cannot be used (.e.g because they cause side effects, like transferring funds or launching nukes). Mocks are used to write assertions about the way they are used – e.g. if they were called, which arguments were used etc. It is a flagship technique of interaction-based testing – checking how objects under test use their collaborators (other objects).

Immutable means that the tuple has a fixed value and cannot change. You cannot add, delete or modify items in a tuple. Immutable objects are useful when you need a constant hash value. The most popular example is the key to a Python dictionary.

Matt Layman: Starting the Onboarding Flow - Building SaaS #49
2020-03-26 00:00:00
In this episode, we worked on the progress element that will display in every step of the onboarding flow. I added some labels and styled the banner using Tailwind CSS. At the end of the stream, we boxed in the shape of the welcome page with some placeholder elements. The very first thing I did was insert a top bar that was unstyled to the top of the welcome page. We added some placeholder text for each of the steps in the onboarding flow.

Stack Abuse: Reading and Writing CSV Files in Python with Pandas
2020-03-25 16:43:56
There are many ways of reading and writing CSV files in Python. There are a few different methods, for example, you can use Python's built in open() function to read the CSV (Comma Separated Values) files or you can use Python's dedicated csv module to read and write CSV files. Depending on your use-case, you can also use Python's Pandas library to read and write CSV files.

2020-03-24 14:00:00
NumPy is the fundamental Python library for numerical computing. Its most important type is an array type called ndarray. NumPy offers a lot of array creation routines for different circumstances. arange() is one such function based on numerical ranges. It’s often referred to as np.arange() because np is a widely used abbreviation for NumPy.

Podcast.__init__: A Flexible Open Source ERP Framework To Run Your Business
2020-03-23 12:59:10
Running a successful business requires some method of organizing the information about all of the processes and activity that take place. Tryton is an open source, modular ERP framework that is built for the flexibility needed to fit your organization, rather than requiring you to model your workflows to match the software. In this episode core developers Nicolas Évrard and Cédric Krier are joined by avid user Jonathan Levy to discuss the history of the project, how it is being used, and the myriad ways that you can adapt it to suit your needs. If you are struggling to keep a consistent view of your business and ensure that all of the necessary workflows are being observed then listen now and give Tryton a try.

BreadcrumbsCollector: mypy: how to use it in my project?
2020-03-20 19:17:00
Type annotations are a great addition to Python. Thanks to them, finally our IDEs are able to provide good quality autocompletion. They did not turn Python into statically typed language, though. If you put a wrong annotation (or forget to update it after code change), Python will still happily try to execute your program. It just may fail miserably. Type annotations are like comments – they do not really have any influence on the way how your program works. They have also the same disadvantage – once they become obsolete, they start leading developers astray. Type annotations advantage is that they have a very specific format (unlike comments) so can be used to build tools that will make your life easier and code better. In this article, you will learn how to start using mypy, even if you like to add it to your existing project.

Python 4 Kids: Python is No Good for Mortality Rates
2020-03-20 02:36:32
Here we are at the uptick in the Covid 19 pandemic. There are many sources of data which list infections and deaths as a result of the virus. It’s very tempting to want to put your Python skills to use and crunch some numbers on the infection. By and large, go for it, but one thing I’d ask you not to do is to try to calculate a “mortality rate”. This is not because Python can’t do division but, rather, working this number out is conceptually pretty tricky. It’s something that epidemiologists need to get a lot of training in to do correctly.  You can’t just take the deaths column and divided it by the infected column because the two numbers are not properly related. For example:

School has ended but my 8yo is totally angry with Covid-19 … is asking if it could be killed by throwing a host of atomic bombs on it … to which my answer is: “nuclear power can not kill covid-19 even it would kill all human life on the planet. But yes, sincerely, i understand your frustration — let’s take a bicicly ride together.”

Podcast.__init__: Getting A Handle On Portable C Extensions With hpy
2020-03-16 23:18:10
One of the driving factors of Python’s success is the ability for developers to integrate with performant languages such as C and C++. The challenge is that the interface for those extensions is specific to the main implementation of the language. This contributes to difficulties in building alternative runtimes that can support important packages such as NumPy. To address this situation a team of developers are working to create the hpy project, a new interface for extension developers that is standardized and provides a uniform target for multiple runtimes. In this episode Antonio Cuni discusses the motivations for creating hpy, how it benefits the whole ecosystem, and ways to contribute to the effort. This is an exciting development that has the potential to unlock a new wave of innovation in the ways that you can run your Python code.

Stack Abuse: Default Arguments in Python Functions
2020-03-16 12:29:00
Functions in Python are used to implement logic that you want to execute repeatedly at different places in your code. You can pass data to these functions via function arguments. In addition to passing arguments to functions via a function call, you can also set default argument values in Python functions. These default values are assigned to function arguments if you do not explicitly pass a parameter value to the given argument. Parameters are the values actually passed to function arguments.

Anarcat: Remote presence tools for social distancing

As a technologist, I've been wondering how I can help people with the rapidly spreading coronavirus pandemic. With the world entering the "exponential stage" (e.g. Canada, the USA and basically all of Europe), everyone should take precautions and limit practice Social Distancing (and not dumbfuckery). But this doesn't mean we should dig ourselves in a hole in our basement: we can still talk to each other on the internet, and there are great, and free, tools available to do this. As part of my work as a sysadmin, I've had to answer questions about this a few times and I figured it was useful to share this more publicly.

However, I was quite new to WebRTC and had some problems getting my head around the basic concepts, as well as creating a working solution. There are many tutorials available, but most of them are incomplete, obsolete, or forced me to use some third party services (e.g. Google Firebase), that only made the whole process more complicated to setup and more difficult to understand.

Real Python: Using the Python defaultdict Type for Handling Missing Keys
2020-03-11 14:00:00
A common problem that you can face when working with Python dictionaries is to try to access or modify keys that don’t exist in the dictionary. This will raise a KeyError and break up your code execution. To handle these kinds of situations, the standard library provides the Python defaultdict type, a dictionary-like class that’s available for you in collections.

2020-03-10 17:15:02
Lists are a fundamental data type in the Python programming language. A list is a mutable sequence that is typically a collection of homogeneous items. Mutable means that you can change a list after its creation. You will frequently see lists that contain other lists. These are known as nested lists. You will also see lists that contain all manner of other data types, such as dictionaries, tuples or objects.

IslandT: Lists in python – Part One
2020-03-10 05:42:53
Lists in python are just like an array in Java, a python list is liked an apartment consists of many rooms where you will find a person living inside each of those rooms. The only difference between the Python list and the Java array is that Java is very strict when it comes to the type of element which is allowed to stay inside a particular type of array which means if that array belongs to the integer type then only integer will be allowed to stay inside that array, whereas Python will allow every data types to stay together inside a single list. For example, in the below program, we will put a string, a number, and a dictionary within that same list and then use those data types according to our needs.

Podcast.__init__: Open Source Machine Learning On Quantum Computers With Xanadu AI
2020-03-10 02:05:48

IslandT: What is python programming language?
2020-03-02 06:52:34
Python is the most popular programming language in the world, above Java and above C/C++/C#. We can use Python for free to develop web applications or desktop software and then sell that application or software in the marketplace. Just like Perl, Python source code is also available under the GNU General Public License (GPL) which guarantees end-users the freedom to run, study, share and modify the source code. Python is created by Guido van Rossum. In my opinion, Python programming language looks like the combination of Java, Javascript, and Perl programming language, therefore there is nothing new and nothing we have not seen before if we have already learned those programming languages above.

Reuven Lerner: Want to spend more time coding Python, and less time on Stack Overflow?
2020-02-26 16:58:01
How many times a day do you visit Stack Overflow?  (If you’re like most programmers, the answer is “many.”)  Wouldn’t it be nice to just be able to write Python code, without interrupting your work every few hours to check (or double-check) something? After all, whether you’re a data scientist, app developer, or just a hobbyist, your goal isn’t to search for answers to your problems. Your goal is to actually solve those problems. Consider what would happen if you were able to use all of that search-for-answers time on actually solving problems:

Real Python: The Beginner's Guide to Python Turtle
2020-02-26 14:00:00
When I was a kid, I used to learn Logo, a programming language that involved a turtle that you could move around the screen with just a few commands. I remember feeling like a computer genius as I controlled this little object on my screen, and this was what got me interested in programming in the first place. The Python turtle library comes with a similar interactive feature that gives new programmers a taste of what it’s like to work with Python.

The No Title® Tech Blog: Book review - Machine Learning with Python for Everyone, By Mark E. Fenner
2020-02-26 02:10:00
Machine learning, one of the hottest tech topics of today, is being used more and more. Sometimes as the best tool for the job, other times perhaps as a buzzword that is mainly used as a way to make a product look cooler. However, without knowing what ML is and how it works behind the scenes, it’s very easy to get lost. But this book does a great job in guiding you all the way up from very simple math concepts to some sophisticated machine learning techniques.

Podcast.__init__: Reducing The Friction Of Embedded Software Development With PlatformIO
2020-02-25 03:25:01
Embedded software development is a challenging endeavor due to a fragmented ecosystem of tools. Ivan Kravets experienced the pain of programming for different hardware platforms when embroiled in a home automation project. As a result he built the PlatformIO ecosystem to reduce the friction encountered by engineers working with multiple microcontroller architectures. In this episode he describes the complexities associated with targeting multiple platforms, the tools that PlatformIO offers to simplify the workflow, and how it fits into the development process. If you are feeling the pain of working with different editing environments and build toolchains for various microcontroller vendors then give this interview a listen and then try it out for yourself.

The main goal of these tutorials series is learning to deal with python source code using the new concepts of execution in python 3. When two or more events are concurrent it means that they are happening at the same time. Concurrent programming is not equivalent to parallel execution. In computing, concurrency is the execution of pieces of work or tasks by a computer at the same time.

We are not going to restrict ourselves to a single library or framework; however, there is one that we will be using the most frequently, the Open CV library. We will start off by talking a little about image processing and then we will move on to see different applications/scenarios where image processing can come in handy. So, let's begin!

Anarcat: The CLA Denial-Of-Service attack
2020-02-24 15:32:53
I just stumbled upon this weird mind bender this morning. I have found what I believe is a simple typo in the Ganeti documentation which has a trivial fix. But then, before I submitted a PR to fix it, I remembered that I had trouble getting stuff merged in Ganeti before. That's because they require a CLA (which is already annoying enough) that requires a Google account to sign (which is simply unacceptable). So that patch has been sitting there for months, unused and I haven't provided a patch for the other issue because of this very problem.

This is a preposterous table I just made up after reading Wikipedia's History of Programming Languages. I was trying to figure out which programming language or environment this article might be refering to. The article talks about some of the Canadian federal government's computer systems "falling apart" because they are "60 years" old. Everyone cried "COBOL" but I figured there might be other culprits.

Real Python: Python '!=' Is Not 'is not': Comparing Objects in Python
2020-01-29 14:00:00
There’s a subtle difference between the Python identity operator (is) and the equality operator (==). Your code can run fine when you use the Python is operator to compare numbers, until it suddenly doesn’t. You might have heard somewhere that the Python is operator is faster than the == operator, or you may feel that it looks more Pythonic. However, it’s crucial to keep in mind that these operators don’t behave quite the same.

Though you can translate anything by simply going to the Google Translate web page, you can also integrate Google Translate API into your web applications or desktop programs. The best thing about the API is that it is extremely easy to set up and use.

Podcast.__init__: Simplifying Social Login For Your Web Applications
2020-01-27 03:14:01
A standard feature in most modern web applications is the ability to log in or register using accounts that you already own on other sites such as Google, Facebook, or Twitter. Building your own integrations for each service can be complex and time consuming, distracting you from the features that you and your users actually care about. Fortunately the Python social auth library makes it easy to support third party authentication with a large and growing number of services with minimal effort. In this episode Matías Aguirre discusses his motivation for creating the library, how he has designed it to allow for flexibility and ease of use, and the benefits of delegating identity and authentication to third parties rather than managing passwords yourself.

Databases are a crucial part of modern applications since they store the data used to power them.

Though initially done via dedicated SQL tools, we've quickly moved to using SQL from within applications to perform queries.

Abhijeet Pal: Python Program to Convert Octal Number to Decimal and vice-versa
2020-01-24 12:21:33
The octal numeral system, or oct for short, is the base-8 number system and uses the digits 0 to 7. The main characteristic of an Octal Numbering System is that there are only 8 distinct counting digits from 0 to 7 with each digit having a weight or value of just 8 starting from the least significant bit (LSB). In the decimal number system, each digit represents the different power of 10 making them base-10 number system. Problem definition Create a python program to convert an octal number into a decimal number. Algorithm for octal to decimal conversion Take an octal number as input. Multiply each digit of the octal number starting from the last with the powers of 8 respectively. Add all the multiplied digits. The total sum gives the decimal number. Program num = input("Enter an octal number :") OctalToDecimal(int(num)) def OctalToDecimal(num): decimal_value = 0 base = 1 while (num): last_digit = num % 10 num = int(num / 10) decimal_value += last_digit * base base = base * 8 print("The decimal value is :",decimal_value) Output Enter an octal number :24 The …

An HTTP request coming from a browser includes a URL describing which resource Django should produce. Since URLs can come in many forms, we must instruct Django on the kinds of URLs that our web application can handle.

Abhijeet Pal: Python Program to Find the Factors of a Number
2020-01-14 08:07:35
The factor of any number is a whole number which exactly divides the number into a whole number without leaving any remainder. For example, 3 is a factor of 9 because 3 divides 9 evenly leaving no remainder. Problem Create a Python program to find all the factors of a number. Algorithm Step 1:  Take a number Step 2: Loop over every number from 1 to the given number Step 3: If the loop iterator evenly divides  the provided number i.e. number % i == 0 print it. Program number = 69 print("The factors of {} are,".format(number)) for i in range(1,number+1): if number % i == 0: print(i) Output The factors of 69 are, 1 3 23 69 Print factors of a user-provided number number = int(input("Enter a number ")) print("The factors of {} are,".format(number)) for i in range(1,number+1): if number % i == 0: print(i) Output Enter a number 469 The factors of 469 are, 1 7 67 469

Abhijeet Pal: Python Program to Calculate Power of a Number
2020-01-14 06:48:38
Problem Definition Create a Python program to take two numbers from the user one being the base number another the exponent then calculate the power. Program import math base_number = float(input("Enter the base number")) exponent = float(input("Enter the exponent")) power = math.pow(base_number,exponent) print("Power is =",power) Output Enter the base number2 Enter the exponent4 Power is = 16.0 The built-in math module provides a number of functions for mathematical operations. The pow() method takes a base number and exponent as parameters and returns the power. Since in Python, there is always more than one way of achieving things calculating power with the exponentiation operator is also possible. The exponentiation operator x**yevaluates to power. Program base_number = int(input("Enter the base number")) exponent = int(input("Enter the exponent")) power = base_number ** exponent print("Result is =",power) Output Enter the base number2 Enter the exponent5 Result is = 32

Reversing a number mathematically The algorithm below is used to reverse a number mathematically with time complexity of O(log n) where n is input number. Algorithm Input : num (1) Initialize rev_num = 0 (2) Loop while num > 0 (a) Multiply rev_num by 10 and add remainder of num divide by 10 to rev_num (b) Divide num by 10 (3) Return rev_num  Program num = 12345 rev_num = 0 while num != 0: rev_num = rev_num * 10 rev_num = rev_num + (num%10) num = num // 10 print(rev_num) Output 54321 Using reversed() method Python’s built in reversed() method returns an iterator that accesses the given sequence in the reverse order. Program # input num = 1234 rev_iterator = reversed(str(num)) rev_num = "".join(rev_iterator) print(rev_num) Output 4321 Note that the reversed() method doesn’t accept integer as a parameter therefore data type is converted to a string.

Abhijeet Pal: Python Program To Display Characters From A to Z
2020-01-13 13:16:12
Problem Definition Create a Python program to display all alphabets from A to Z. Solution This article will go through two pythonic ways to generate alphabets. Using String module Python’s built-in string module comes with a number of useful string functions one of them is string.ascii_lowercase Program import string for i in string.ascii_lowercase: print(i, end=" ") Output a b c d e f g h i j k l m n o p q r s t u v w x y z The string.ascii_lowercase method returns all lowercase alphabets as a single string abcdefghijklmnopqrstuvwxyzso the program is simply running a for loop over the string characters and printing them. Similarly for uppercase A to Z letters. Program import string for i in string.ascii_uppercase: print(i, end=" ") Output A B C D E F G H I J K L M N O P Q R S T U V W X Y Z Using chr() Function The chr() function in Python returns a Unicode character for the provided ASCII value, hence chr(97) returns “a”.

Podcast.__init__: Checking Up On Python's Role in DevOps
2020-01-06 03:22:52
Python has been part of the standard toolkit for systems administrators since it was created. In recent years there has been a shift in how servers are deployed and managed, and how code gets released due to the rise of cloud computing and the accompanying DevOps movement. The increased need for automation and speed of iteration has been a perfect use case for Python, cementing its position as a powerful tool for operations. In this episode Moshe Zadka reflects on his experiences using Python in a DevOps context and the book that he wrote on the subject. He also discusses the difference in what aspects of the language are useful as an introduction for system operators and where they can continue their learning.

Abhijeet Pal: Adding Custom Model Managers In Django
2020-01-04 09:18:21
A manager is an interface through which database query operations are provided to Django models. At least one Manager exists for every model in a Django application, objects is the default manager of every model that retrieves all objects in the database. However, one model can have multiple model managers, we can also build our own custom model managers by extending the base manager class. In this article, we will learn how to create custom model managers in Django. Creating Custom Model Managers In this article, we will build a model manager for a blog application. class Post(models.Model): title = models.CharField(max_length=200) content = models.TextField() created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) active = models.BooleanField(default=False) def __str__(self): return self.title As we know objects is the default model manager for every model, therefore Post.objects.all() will return all post objects. The objects method is capable of doing all basic QuerySets then why would we need a custom model manager? There are two reasons you might want to customize a Manager – To add extra Manager methods. To modify the initial QuerySet the Manager returns. Let’s …

Abhijeet Pal: Creating Feeds with Django
2020-01-03 16:14:04
Django ships with built-in syndication feed generating framework, which is used to generate dynamic Atom and RSS feeds. RSS is an abbreviation for Really Simple Syndication, it’s a way to have information delivered to you instead of you having to go find it. RSS is basically a structured XML document that includes full or summarized text along with other metadata such as published date, author name, etc. Creating RSS Feeds with Django In this article, we are going to generate feeds for a blog application following is the models.py file. class Post(models.Model): title = models.CharField(max_length=200, unique=True) slug = models.SlugField(max_length=200, unique=True) author = models.ForeignKey( User, on_delete=models.CASCADE, related_name="blog_posts" ) updated_on = models.DateTimeField(auto_now=True) content = models.TextField() created_on = models.DateTimeField(auto_now_add=True) status = models.IntegerField(choices=STATUS, default=0) class Meta: ordering = ["-created_on"] def __str__(self): return self.title def get_absolute_url(self): from django.urls import reverse return reverse("post_detail", kwargs={"slug": str(self.slug)}) Create a new file feeds.py inside the application directory. from django.contrib.syndication.views import Feed from django.template.defaultfilters import truncatewords from .models import Post from django.urls import reverse class LatestPostsFeed(Feed): title = "My blog" link = "" description = "New posts of my blog." …

Abhijeet Pal: Creating Sitemaps in Django
2020-01-03 07:12:54
Django comes with baked-in functionality for generating sitemaps dynamically using the sitemap framework. A sitemap is an XML file that informs search engines such as Google, the pages of your website, their relevance, and how frequently they are updated. Using sitemaps facilitates crawlers indexing the site, therefore sitemap plays a crucial role in modern SEO (Search Engine Optimization). In this article, we will go through the process of creating sitemaps in Django. Creating Sitemaps in Django Considering the scope of the article I am assuming you have basic knowledge of Django and have a project up and running if not read the following article first. Building A Blog Application With Django Installation Add 'django.contrib.sitemaps' in INSTALLED_APPS setting. INSTALLED_APPS += ( 'django.contrib.sitemaps',) Make sure your TEMPLATES setting contains a DjangoTemplates backend whose APP_DIRS options is set to True.

With that it should be relatively easy to target an off-screen render to a particular device. (The extension allows `eglQueryDeviceStringEXT` to respond to `EGL_DRM_DEVICE_FILE_EXT`). Happy New Year all.

Armin Ronacher: I'm not feeling the async pressure
2020-01-01 00:00:00
Async is all the rage. Async Python, async Rust, go, node, .NET, pick your favorite ecosystem and it will have some async going. How good this async business works depends quite a lot on the ecosystem and the runtime of the language but overall it has some nice benefits. It makes one thing really simple: to await an operation that can take some time to finish. It makes it so simple, that it creates innumerable new ways to blow ones foot off. The one that I want to discuss is the one where you don't realize you're blowing your foot off until the system starts overloading and that's the topic of back pressure management. A related term in protocol design is flow control.

So I've now spent the last day and a half playing with getting EGL offscreen rendering working on Linux. There are two major ways to do off-screen rendering with EGL and OpenGL. In the first, you use a pbuffer surface, that surface is basically a purpose-defined surface-type for off-screen backing of a renderer. When I use the EGL enumeration API we always seem to get pbuffer compatible visuals (and *not* window compatible ones).

Armin Ronacher: Open Source Migrates With Emotional Distress

Legacy code is bad and if you keep using it, it's really your own fault. There are many variations of the same thing floating around in Open Source communities and it always comes down to the same thing: at one point something is being declared old and it has to be replaced by something newer which is better. That better typically has some really good arguments on its side: we learned from our mistakes, it was wrong to begin with or something along the lines of it being impure or that it propagated bad ideas. Maybe that new thing only supports the newest TLS/SSL and you really should not longer be using the old versions because they are insecure.

Stack Abuse: Executing Shell Commands with Python
2019-12-10 13:10:00
Repetitive tasks are ripe for automation. It is common for developers and system administrators to automate routine tasks like health checks and file backups with shell scripts. However, as those tasks become more complex, shell scripts may become harder to maintain.

2019-12-10 12:30:00
We asked our friend Miro to try using Pytest with PyCharm. Miro has background in test automation, Python, DevOps and metal music. Since he was new to the set-up he would be the ideal person to write a beginner's guide. This is his take.

Robin Wilson: Creating an email service for my son’s childhood memories with Python
2019-12-10 11:23:01
For a number of years – since my now-toddler son was a small baby – I’ve been keeping track of various childhood achievements or memories. When I first came up with this I was rather sleep-deprived, and couldn’t decide what the best way to store this information would be – so I went with a very simple option. I just created a Word document with a table in it with two columns: the date, and the activity/achievement/memory. For example:

Stein Magnus Jodal: pathlib and paths with arbitrary bytes
2019-12-10 00:00:00
The ">">pathlib module was added to the standard library in Python 3.4, and is one of the many nice improvements that Python 3 has gained over the past decade. In three weeks, Python 3.5 will be the oldest version of Python that still receive security patches. This means that the presence of pathlib can soon be taken for granted on all Python installations, and the quest towards replacing os.path can begin for real.

TechBeamers Python: Generate a Python Random Number
2019-12-07 19:09:26
Here is a quick guide on Python’s random number. You can always refer to it whenever you need to generate a random number in your programs. Python has a built-in random module for this purpose. It exposes several methods such as randrange(), randint(), random(), seed(), uniform(), etc. You can call any of these functions to generate a Python random number. Usually, a random number is an integer, but you can generate float random also. However, you first need to understand the context as a programmer and then pick the right function to use.

A list is one of the fundamental data types in Python. Every time you come across a variable name that's followed by a square bracket [], or a list constructor, it is a list capable of containing multiple items, making it a compound data type. Similarly, it is also a breeze to declare a new list and subsequently add one or more items to it.

My son goes to a nursery part-time, and the nursery uses a system called ParentZone from Connect Childcare to send information between us (his parents) and nursery. Primarily, this is used to send us updates on the boring details of the day (what he’s had to eat, nappy changes and so on), and to send ‘observations’ which include photographs of what he’s been doing at nursery. The interfaces include a web app (pictured below) and a mobile app:

Podcast.__init__: Making Complex Software Fun And Flexible With Plugin Oriented Programming
2019-12-03 03:44:04
Starting a new project is always exciting because the scope is easy to understand and adding new features is fun and easy. As it grows, the rate of change slows down and the amount of communication necessary to introduce new engineers to the code increases along with the complexity. Thomas Hatch, CTO and creator of SaltStack, didn’t want to accept that as an inevitable fact of software, so he created a new paradigm and a proof-of-concept framework to experiment with it. In this episode he shares his thoughts and findings on the topic of plugin oriented programming as a way to build and scale complex projects while keeping them fun and flexible.

Mahmoud Hashemi: Thanks, 201X!
2019-12-02 18:00:00
Thought I'd take a Sunday afternoon to reflect on, oh I don't know, a decade. Been a long ten years, but it's flown past. This particular decade happens to coincide with my first years of full-time professional software engineering. The Quantity I can't possibly summarize it all, and if I tried, it'd still be colored by what's on my mind right now. But I can point to the artifacts I tried to leave along the way: Twitter FWIW1 (2008+) ~20 Open-Source Projects (2012+) ~15 Hatnote Projects (2013+, follow us) ~25 entries on this blog (2015+) +7 here (2014-2016) Not including pythondoeswhat.com or blog.hatnote.com (or other posts on the blogs only real heads know) ~10 Talks (2016+) Lest I forget: O'Reilly's Enterprist Software with Python (2016) And several podcast/media appearances calver.org (2016) and 0ver.org (2018) (Versioning is a fun pastime) Pyninsula (2017+) - YouTube, Meetup, Email Announce Taking a chronological look at each of the above, I'm relieved to see obvious growth. If I were to highlight one resource, it would probably be the talks. Despite the stress of preparation and delivery, I'm least concerned with having a massive miscommunication when we're all in the room and I can see the points hitting home. It's impossible to pick a favorite, but Ask the Ecosystem (2019), the Restructuring Data lightning talk (2018), and The Packaging Gradient (2017) seem like audience faves from where I'm sitting. The Quality Each project, post, and talk had its own reward, but I guess I've got more than just those to show for the decade. On the more profit-driven side, I built tools and teams at PayPal, but once I could manage the risk, I got to dip into startups for the last few years. Lucky for me, it wasn't a total bust, and the wife and I bought a place in my favorite neighborhood (in the USA). Not a millionaire, but I'm hoping and working for a world where no one has to be. More recently, the Python Software Foundation made me a Fellow. This isn't something I can be nonchalant about, and I'm not going to understate how much this means, to me, working in a field like software, where concrete symbols of progress are alternatingly elusive and vanishing. Plus it's Python, and reciprocated love is nice. I have hundreds of people to thank for helping me reach this point, and I have to thank the PSF for dedicating the time to ramping up these awards. They've convinced me more than ever that we need more institutions to build this sort of advancement. To all of you, thank you. The Struggle I like to think I managed to do all of the above while staying away from industry hype, on the principle that massive speculative capital influx isn't where real value is added to society, and doesn't generate the kind of innovation that excites me. I may have been naïve, but I came to Silicon Valley with an idea about the transformative power of software. Changing times may illustrate a grittier interpretation than the one I had and have, but I continue to hold dear software's potential for positive impact. If you've felt that vision waver, let me tell you, you're not alone. In the past decade, I've seen too many engineers sucked in by new technologies and ventures, only to find themselves alienated from their work. Episodes ranging from an afternoon lost to debugging Docker/k8s clusters, to years of work disappearing at the end of a VC runway. Nothing has been harder to watch than those bedraggled-but-persistent idealists regroup, each time a bit more cynical than the last. Even if its seeming intractibility has taken it from the center stage, the burnout conversation continues to smolder, because there's no issue realer. I know; I released more ceramics than software back in 2014. Some problems can be solved by paying the maintainers, but I think the vastly bigger issue is around losing the human connection between the real effort software takes and the real benefits it brings, combined with FOSS's dearth of collaborators in supporting roles (QA, product/project/release management). That's why I'm incredibly thankful for the Wikimedia community for always being there, patient with schedules and issues, as long as the software got the job done. It can be a challenge to juggle projects, but I tell every budding engineer: find that direct connection to people who will appreciate your work, and avoid cynicism at all costs. There are some interesting prospects in the works, but I'm keeping this post retro. Besides, if 2029 rolls around and all I did was break even with 2009-19, I don't see how I can be disappointed. Thanks again for everything in 201X, and for sticking with me in 202X. Despite using Twitter for over a decade, the process of tweeting feels so perfunctory, and the service itself so tenuous, that I still can't bring myself to invest the time. I mostly use it to crosspost my blog posts or help friends promote their posts/projects. But until I start an email newsletter, or really get on top of yak.party, it's still the best I got for announcing where I'm speaking next. ↩

So as I work through all the OpenGLContext projects to get automatic (or near automatic) releasing, SimpleParse wound up failing on the 3.x branches with a weird xml test failure. But with Python 3.8 the C code just won't import at all. Seems there was a change in Python 3.8 where it does a load-time test for functions in the module and the hand-coded C module triggers it. So I'll have to spend some time on that before I can get the whole stack releasing.

Pandas is a powerful and flexible Python package that allows you to work with labeled and time series data. It also provides statistics methods, enables plotting, and more. One crucial feature of Pandas is its ability to write and read Excel, CSV, and many other types of files. Functions like the Pandas read_csv() method enable you to work with files effectively. You can use them to save the data and labels from Pandas objects to a file and load them later as Pandas Series or DataFrame instances.

Stack Abuse: Using cURL in Python with PycURL
2019-11-19 17:39:05
In this tutorial, we are going to learn how to use PycURL, which is an interface to the cURL library in Python. cURL is a tool used for transferring data to and from a server and for making various types of data requests. PycURL is great for testing REST APIs, downloading files, and so on. Some developers prefer using Postman for testing APIs but PycURL is another suitable option to do so as it supports multiple protocols like FILE, FTPS, HTTPS, IMAP, POP3, SMTP, SCP, SMB, etc. Moreover, PycURL comes in handy when a lot of concurrent, fast, and reliable connections are required.

2019-11-15 09:48:59
Here is PoC based on qubesadmin API which can auto attach USB devices to any VM as required. By default Qubes auto attaches any device to the sys-usb VM, that helps with bad/malware full USB devices. But, in special cases, we may want to select special devices to be auto attached to certain VMs. In this PoC example, we are attaching any USB storage device, but, we can add some checks to mark only selected devices (by adding more checks), or we can mark few vms where no device can be attached.

Sumana Harihareswara - Cogito, Ergo Sumana: My New Title, Improving pip, Availability For Work, And SSL (No, The Other One)
2019-11-12 23:29:19
Seeking developers for paid contract on pip; apply by Nov. 22 One is that I helped the Packaging Working Group of the Python Software Foundation get funding for a long-needed improvement to pip. I led the writing of a few proposals -- grantwriting, to oversimplify -- and, starting possibly as soon as next month, contractors will start work. As Dustin Ingram explains: Big news: the Python Packaging Working Group has secured >$400K in grants from multiple funders (TBA) to improve one of the most fundamental parts of pip: its dependency resolver. https://pyfound.blogspot.com/2019/11/seeking-developers-for-paid-contract.html The dependency resolver is the algorithm which takes multiple constrained requirements (e.g. "some_package>=1.0,=2.0") and finds a version of all dependencies (and sub-dependencies) which satisfy all the constraints. https://pip.pypa.io/en/stable/user_guide/#requirements-files Right now, pip's resolver mostly works for most use cases... However the algorithm it uses is naïve, and isn't always guaranteed to produce an optimal (or correct) result. ..... These funds will pay multiple developers to work on completing the design, implementation and rollout of this new dependency resolver for pip, finally closing issue #988. Not only will this give pip a better resolver, but it will "enable us to untangle pip’s internals from the resolver, enabling pip to share code for dependency resolution with other packaging tooling". https://pradyunsg.me/blog/2019/06/23/oss-update-1/ This is great news for pip and Python packaging in general. Huge shout out to @pradyunsg for his existing work on the resolver issue and guidance here, and to @brainwane for all her tireless work acquiring and directing funding for Python projects. If you or your organization is interested in participating in this project, we've just posted the RFP, which includes instructions for submitting proposals, evaluation criteria and scope of work. https://github.com/python/request-for/blob/master/2020-pip/RFP.md If you're interested, please apply by 22 November. NYU, Secure Systems Lab, and my new title In further news: New York University's Tandon School of Engineering has now announced that: ...pioneering open-source software nonprofits the Tor Project and Python Software Foundation (PSF) are the newest tenants at 370 Jay Street, a recently renovated addition to the University’s engineering and applied sciences programs in Downtown Brooklyn. NYU Tandon is donating work space to both organizations for their first offices in New York City. .... Sumana Harihareswara, a volunteer with the PSF’s Packaging Working Group and a contracted project manager for the Python Packaging Index, is among the first to move into the NYU facility. Harihareswara is also a visiting scholar in [Professor Justin] Cappos's Secure Systems Lab. Yes, I am now a Visiting Scholar at NYU's Secure Systems Lab and I get to use an office with a door, shelves, whiteboards, and so on (per the picture at right). If you contribute to Python packaging/distribution tools and live in/near or sometimes visit New York City, let me know and perhaps we could cowork a bit? The Secure Systems Lab stewards The Update Framework (TUF) and related projects, and works to improve the security of the software supply chain. The Python Package Index is likely going to implement TUF to add cryptographic signatures to packages on PyPI, and so I've gotten to give TUF's developers some advice to help that work move along. (I won't be the manager on that project but I'll be watching with great interest.) PSF projects I'm grateful to get to help connect the Python Software Foundation with more resources and volunteers. Changeset's current and recent projects have mostly been for the PSF. Last month we finished accessibility, security, and internationalization work on PyPI that was funded by the Open Technology Fund, and Changeset's work on communicating about the sunsetting of Python 2.x continues and will go through April 2020. Availability for one-day engagements in San Francisco in February But I am interested in taking on new clients for short engagements starting in February 2020. In particular, I will be in the San Francisco Bay Area in mid- to late February. If you're in SF or nearby, I could offer you a one-day engagement doing one of the following: developing a contributor outreach/intake strategy researching potential funders and writing a rough draft of a grant proposal auditing and improving your developer onboarding documents I'd spend a little time talking with you, then sit in your office and finish the document before leaving that afternoon. (Photo at right provides a sample of how I look while sitting.) Drop me a line for a free initial 30-minute chat and we can talk pricing.

Real Python: When to Use a List Comprehension in Python
2019-11-06 14:00:00
Python is famous for allowing you to write code that’s elegant, easy to write, and almost as easy to read as plain English. One of the language’s most distinctive features is the list comprehension, which you can use to create powerful functionality within a single line of code. However, many developers struggle to fully leverage the more advanced features of a list comprehension in Python. Some programmers even use them too much, which can lead to code that’s less efficient and harder to read.

The function annotations refer to syntax parameters with an expression. def my_function(x: expression, y: expression = 5): ...For example: &gt;&gt;&gt; def show(myvar:np.float64): ... print(type(myvar)) ... print(myvar) ... &gt;&gt;&gt; show(1.1) 1.1 &gt;&gt;&gt; def files(filename: str, dot='.') -&gt; list: ... print

Zero-with-Dot (Oleg Żero): Using dunder methods to refine data model
2019-11-03 23:00:00
Practically everyone who has ever used Python came across at least one of the so-called Python magic methods. Dunder methods, as they also called that way, are Python’s special functions that allow users to hook into some specific actions being performed. Probably the most frequently encountered one is the __init__ method. It is called when instantiating a new object from a class and by overriding it, we can gain control over that process.

This tutorial covers the following topic – Python Write File/Read File. It describes the syntax of the writing to a file in Python. Also, it explains how to write to a text file and provides several examples for help. For writing to a file in Python, you would need a couple of functions such as Open(), Write(), and Read(). All these are built-in Python functions and don’t require a module to import. There are majorly two types of files you may have to interact with while programming. One is the text file that contains streams of ASCII or UNICODE (UTF-8)

This is a good starting point before you make the jump to more powerful front-end frameworks, like Angular or React.

Reuven Lerner: Early-bird pricing for Weekly Python Exercise ends tomorrow
2019-10-28 17:24:56
My native language is English: I grew up speaking it at home and school, and it’s my preference when reading, writing, and speaking. I studied in US schools through 12 grade, and then got both a bachelor’s degree and a PhD at American universities.  I’ve been writing for years, including 20 years as a columnist at Linux Journal. Am I fluent in English? Yes, I’d say so.  And yet, I’m always reading tidbits about the history of English, how to speak more clearly, and how sharpen the language I use when writing.Why? Because fluency isn’t a video game, in which you get a flashing sign saying, “Achievement unlocked: You’re fluent!”  No matter how fluent you currently are, there are ideas, techniques, and practices that you can still learn. You can always become better.  How do you improve your fluency? The best way, of course, is practice. No matter how fluent you already are, more practice is always good.  As the old saying goes, the best way to become a good writer is to write. And the best way to become a better speaker is to speak.  And so forth. What’s true for English, and other languages, is true for programming languages, as well.  If you want to be a better Python programmer, then you should be writing Python code, making mistakes, and learning from those mistakes.  Better yet, you should be discussing your mistakes (and techniques) with others, so that you can compare ideas and techniques, and learn from your peers.This is the thinking that has driven my work with Weekly Python Exercise. Each of the six WPE courses is designed to help you become a more fluent programmer.A new advanced-level cohort is starting on November 5th. But tomorrow (Tuesday, October 29th) is the last day you can sign up for the early-bird price of $80. Here’s what some people have said about previous cohorts of WPE, when asked what they thought:

The other day, I was using pandas to clean some messy Excel data that included several thousand rows of inconsistently formatted currency values. When I tried to clean it up, I realized that it was a little more complicated than I first thought. Coincidentally, a couple of days later, I followed a twitter thread which shed some light on the issue I was experiencing. This article summarizes my experience and describes how to clean up messy currency fields and convert them into a numeric value for further analysis.

2019-10-28 09:47:51
This tutorial covers the following topic – Python Zip. It describes the syntax of the zip() function in Python. Also, it explains how the zip works and how to use it with the help of examples. The zip() function allows a variable number of arguments (0 or more), but all iterables. The data types like Python list, string, tuple, dictionary, set, etc. are all of the iterable types. It groups the corresponding elements of all input iterables to form tuples, consolidates, and returns as a single iterable. Let’s check out about the Python zip function in more detail.

TechBeamers Python: Python Add Two List Elements
2019-10-28 09:20:09
This tutorial covers the following topic – Python Add Two list Elements. It describes four unique ways to add the list items in Python. For example – using a for loop to iterate the lists, add corresponding elements, and store their sum at the same index in a new list. Some of the other methods you can use are using map() and zip() methods. All of these procedures use built-in functions in Python. However, while using the map(), you’ll require the add() method, and zip() will need to be used with the sum() function. Both these routines are defined in

Chris Moffitt: Binning Data with Pandas qcut and cut
2019-10-14 12:25:00
When dealing with continuous numeric data, it is often helpful to bin the data into multiple buckets for further analysis. There are several different terms for binning including bucketing, discrete binning, discretization or quantization. Pandas supports these approaches using the cut and qcut functions. This article will briefly describe why you may want to bin your data and how to use the pandas functions to convert continuous data to a set of discrete buckets. Like many pandas functions, cut and qcut may seem simple but there is a lot of capability packed into those functions. Even for more experience users, I think you will learn a couple of tricks that will be useful for your own analysis.

Andrew Dalke: mmpdb crowdfunding consortium
2019-10-03 12:00:00
How can we raise money to fund open source software development in cheminformatics? It's a hard question. Asking for donations doesn't work – companies might not even have a mechanism to make donations. Consultant-based funding doesn't work that well either, because the cost of developing a general-purpose tool is several times more expensive than developing a tool which only meets the specialized needs of one client, and few clients are willing to subsidize the rest of the field. Proprietary software development solves the problem by getting many people to pay for the same product. Can we learn from the success of proprietary software to get the funds which would certainly be useful in improving open source software?

Sumana Harihareswara - Cogito, Ergo Sumana: Futureproofing Your Python Tools
2019-09-22 18:03:55
If you write software in Python, or depend on something that's in Python, this is for you. Some of you are writing Python 2, or you still have software you depend on that is written in Python 2. January 1st, 2020, is the day that official support for Python 2 stops. So this is a fresh heads-up that you should really have a migration plan and start working on it, to move to Python 3. A lot of stuff you depend on already works on Python 3, and is even pledging to end Python 2 support in or before 2020. And it's easier than it's ever been to port your own code from 2 to 3. You should probably upgrade to Python 3.7. If you want to test out 3.8, it has some changes in how it does warnings, and the first release candidate is out. But, speaking of futureproofing: Code authors move in and out of projects and companies. Six months or 18 months later, maybe you want to update and re-use, re-release or re-deploy code someone else wrote. Or you want your team to be able to reuse what you did after you leave, which means you need the code to run, and you need them to have the password so they can update stuff. Have you written Python code that they have published as a package on the Python Package Index, pypi.org, so other people can use pip install to install it? (And if you want to do that but don't know how? Check out this recently improved tutorial to help you do that.) Publishing that package is a great way of making it so other people can run and deploy it, even within other parts of your organization. But -- who actually has the keys to the castle? Who can upload a new version, or delete a version that has a problem? You should probably make sure multiple people have either "owner" or "maintainer" privileges on the project on PyPI. And you should review your project security history display, which lists sensitive events (such as "file removed from release version 1.0.1") in your PyPI user account and your PyPI project. We just added this display, so you can look at things that have happened in your user account or project, and check for signs someone's stolen your credentials. And then how do you make it a little harder for vandals, spammers, and thieves to take over your account and upload malware or delete all the packages? Add two-factor auth for your login, like you would with your bank. Use an app on your phone to give you a six-digit code, or use a physical security device like a Yubikey. And how do you make it easier to automate publishing new versions of your package, and make it safer to save your credential in the cloud? We've made it possible for you to create an "API token" where all it can do is upload, so you can use that instead of your PyPI password. With well-tested Python 3 migration tools and new PyPI security features, now is a great moment to invest in robustness for Python software that you make or depend on. [This blog post is kind of unwieldy, because it's about too many different things. I won't be publicizing it that much and instead will probably reuse text from it in more focused announcements elsewhere. But I'm publishing it here as a summary of my recent work, because management and communications for the projects above are what I've been working on recently for the Python Software Foundation. (A different kind of summary is on the Clients page for Changeset Consulting.)]

Brett Cannon: A Primer on the Stellar Network
2019-09-21 02:11:27
On September 10, 2019 while I was in London, UK at the Python core dev sprints, I got a message from a user named "spacedrop" on Keybase. The message said I was being given 356.2904939 XLM as a surprise gift of "free Lumens worth $20.98 USD" from the Stellar Development Foundation. All of that screamed "cryptocurrency" which isn't my thing, so my initial reaction was this was some scam by someone who randomly messaged me on Keybase trying to get me to buy into some new cryptocurrency. But then I realized that Keybase wouldn't let a random person message me like that. Curious, I read the rest of the message and found a link to Keybase's "airdrop" announcement which explained that Keybase was actually facilitating the message. Trusting Keybase wasn't getting into anything nefarious,  that enticed me enough to dig a little deeper into Stellar and find their overview page which has the following summary:

I copied various user config files but for uwsgi things didn't very well. On the old server I had uwsgi version 2.0.12-debian and on the new one 2.0.18-debian. The uWSGI changelog is pretty hard to read but I sure don't see any mention of this.

TechBeamers Python: Python Multiple Inheritance (with Examples)
2019-09-16 17:07:03
In this tutorial, we’ll describe Python Multiple Inheritance concept and explain how to use it in your programs. We’ll also cover multilevel inheritance, the super() function, and focus on the method resolution order. In the previous tutorial, we have gone through Python Class and Python (Single) Inheritance. There, you have seen that a child class inherits from a base class. However, Multiple Inheritance is a feature where a class can derive attributes and methods from more than one base classes. Hence, it creates a high level of complexity and ambiguity and known as the diamond problem in the technical world.

Samuel Sutch: Why Python Has Become an Industry Favorite Among Programmers
2019-09-16 03:15:13
With the world stepping towards a new age of technology development, it isn’t hard to imagine a future that will be full of screens. And if so be the case then, demand for people with strong programming skills will definitely rise with more number of people required to develop and support the applications. Python Training is always a good idea for those wishes to be a part of this constantly developing industry. Python language is not only easy to grasp, but emphasizes less on syntax which is why a few mistakes here and there doesn’t give as much trouble as some other languages does.

Samuel Sutch: Python Programming Language Is Considered Better Than Other Languages
2019-09-15 19:46:34
Python is a high-level scripting language. It is easy to learn and powerful than other languages because of its dynamic nature and simple syntax which allow small lines of code. Included indentation and object-oriented functional programming make it simple. Such advantages of Python makes it different from other languages and that’s why Python is preferred for development in companies mostly. In industries, machine learning using python has become popular. This is because it has standard libraries which are used for scientific and numerical calculations. Also, it can be operated on Linux, Windows, Mac OS and UNIX. Students who want to make future in Python are joining online video training courses and python programming tutorial.

TechBeamers Python: Python Heapq (With Examples)
2019-09-14 19:21:44
This tutorial intends to train you on using Python heapq. It is a module in Python which uses the binary heap data structure and implements Heap Queue a.k.a. Priority Queue algorithm. Interestingly, the heapq module uses a regular Python list to create Heap. It supports addition and removal of the smallest element in O(log n) time. Hence, it is an obvious choice for implementing priority queues. The heapq module includes seven functions, the first four of which are used for heap operations. However, you need to provide a list as the heap object itself. Heap data structure has a property

TechBeamers Python: Multiline String in Python with Examples
2019-09-06 19:07:26
This tutorial explains how to create a Python multiline string. It can be handy when you have a very long string. You shouldn’t keep such text in a single line. It kills the readability of your code. In Python, you have different ways to specify a multiline string. You can have a string split across multiple lines by enclosing it in triple quotes. Alternatively, brackets can also be used to spread a string into different lines. Moreover, backslash works as a line continuation character in Python. You can use it to join text on separate lines and create a multiline

Podcast.__init__: Combining Python And SQL To Build A PyData Warehouse
2019-09-02 16:21:36
The ecosystem of tools and libraries in Python for data manipulation and analytics is truly impressive, and continues to grow. There are, however, gaps in their utility that can be filled by the capabilities of a data warehouse. In this episode Robert Hodges discusses how the PyData suite of tools can be paired with a data warehouse for an analytics pipeline that is more robust than either can provide on their own. This is a great introduction to what differentiates a data warehouse from a relational database and ways that you can think differently about running your analytical workloads for larger volumes of data.

Hey! Wassup? Time has passed and it's my final blog for Google Summer of code 2019. Every day was just amazing, I learned a lot, enjoyed a lot, worked a lot. This was really a life-changing experience, I am starting to feel different, look at this world from a different angle and I am myself a-lot different from the time when I started this. Now, about the work: What did you do this week? Well, I finished with the implementation of the documentation page of EOS-Icons. I just created a PR for that. PR link - https://gitlab.com/SUSE-UIUX/eos-icons-landing/merge_requests/22. This documentation page will be published at - https://eos-icons.eosdesignsystem.com/docs.html.  I also finished my final evaluations and created my final work report. What's coming next? I also created a new PR for a few adjustments on the EOS-Icons landing page. I am planning to refactor the code and improve responsiveness. So, I am working on that now. Later I will work on a few other things that are still pending, mainly deploying strapi on Heroku. Did you stuck anywhere? Not really, this week was just about documentation and most of which was already on the readme, so it wasn't that of a big deal. So, ya this was all for my Google Summer of code 2019. Well, I won't be updating this blog for my future work because this was just for GSoC period. Maybe you can check me out on other platforms.

PSF GSoC students blogs: Final Report
2019-08-26 05:55:35
Let’s rewind to the beginning of this year. We had started working on this application way before GSoC had even started. The goal was to have a working application which PSF will be able to use for this year’s GSoC for the management of their students. In this way, we will be able to make sure that students actually use it and we get a clear idea if the application is serving its purpose. I’m glad the plan worked out, because tons of bugs were reported and we could fix them. We also received valuable feedback from all users.

PSF GSoC students blogs: Paginate Django Feeds
2019-08-26 05:48:21
Django has a great framework for generating feeds, but sadly it doesn't support pagination out of the box. Currently we have tons of blogs and the feeds page was loading especially slow with all the pages in it. I was hoping django will have some class variable to enable pagination but I was out of luck. But it had a method which took in the request, so I knew I had to parse the page number from there.

PSF GSoC students blogs: Week 11-12 Check-In
2019-08-26 03:33:15
I am happy to announce that `CollisionHeightfield` is near completion! This week, I added some finalizations to `CollisionHeightfield`, which included improving the collision tests and adding the getter/setters of the class. My next steps would be to push my unit tests to the PR, and provide sample code which demonstrates the new CollisionSolid in action. One goal that I did not get to accomplish was to implement BAM serialization for `CollisionHeightfield`. BAM is one of Panda3D's native file formats, allowing users to export Panda3D objects. Additionally, I did not add collision tests for lines and line segments. `CollisionHeightfield` currently has a collision test for rays, which is probably used more commonly than line/segments in regards to terrain. However, it would be nice to add these tests, especially since they are only slight variants of the ray collision test. Regardless, I am happy to announce that `CollisionHeightfield` is pretty functional as is. That is all for this week, check back next week for my final blog post!

PSF GSoC students blogs: Week #12
2019-08-24 21:36:21
I unsuccessfully tried to resolve the issue with dimensions in NMF. The main problem that I was facing was with specifying the correct dimensions for matrix operations within NMF algorithm and I have yet to identify the correct dimensions. Furthermore, there is no incremental algorithms for NMF as in PCA. Thus, if a large data is given, it becomes infeasible to perform NMF. There are several heuristics to go around this issue with scalability, namely parallel NMF, which divides columns (i.e. features) of the data matrix into several subsets, perform NMF independently on each of the column subsets, and then join the results at the end. Unfortunately, this algorithm was not feasible for LiberTEM because with LiberTEM, one only has access to the rows of the data matrix (i.e., images) and not to the full columns (i.e., feature vectors) at each step. I also tried to clean up jupyter notebook and reorganize.

TechBeamers Python: Python Arrays in a Nutshell
2019-08-21 18:49:08
Python arrays are homogenous data structure. They are used to store multiple items but allow only the same type of data. They are available in Python by importing the array module. Lists, a built-in type in Python, are also capable of storing multiple values. But they are different from arrays because they are not bound to any specific type. So, to summarize, arrays are not fundamental type, but lists are internal to Python. An array accepts values of one kind while lists are independent of the data type. Python List In this tutorial, you’ll get to know how to create

More people don't seem to care enough about how their functions are organized. I think that makes functions a lot more complicated than they have to be. So let's talk about function organization and how multiple exit points can help.

PSF GSoC students blogs: Week 10 &amp; 11
2019-08-20 02:56:27
These two weeks, I've been working on fixing bug #1. I think my algorithm will work in general, but right now the get_cves function doesn't work as I expected, which would cause some problem with data format in futher. Previously, the function will run the query that selects all the version of a product_vendor pair, and then save the result in memory, and using Python code to check whether the version we want is in it. This is actually inefficient and memory-consuming. Therefore, I refactored the code for conducting the query. Right now, the query will only select the version we want and return it to memory. The time for running the whole test cases reduced from 83 seconds to 61 second. So right now, I will try to implement the dynamic programming method and see if the time complexity is not too high.

2019-08-20 01:44:27
The main feature I've been working on this week has been adding pre-planned transforms to pypocketfft in (pypocketfft!28). This will allow users to speed-up cases where many transforms of the same shape are done, without needing to rely on any internal caches. This gives the users a small performance improvement in pypocketfft but adding this to the scipy.fft interface will also allow other backends to benefit. e.g. pyFFTW can have a significantly more expensive planning phase.

Podcast.__init__: Security, UX, and Sustainability For The Python Package Index
2019-08-19 20:06:07
PyPI is a core component of the Python ecosystem that most developer’s have interacted with as either a producer or a consumer. But have you ever thought deeply about how it is implemented, who designs those interactions, and how it is secured? In this episode Nicole Harris and William Woodruff discuss their recent work to add new security capabilities and improve the overall accessibility and user experience. It is a worthwhile exercise to consider how much effort goes into making sure that we don’t have to think much about this piece of infrastructure that we all rely on.

PSF GSoC students blogs: Week 12: Blog Post (#6)
2019-08-19 19:41:51
Last week, I worked on several steps to finalize my project. Some work was put into correcting and improving my pull requests, so they can be merged soon. I created an example file to demonstrate the useability of this project, and opened up a new pull request for it (next to another PR, that introduces the plotting support I implemented the previous week). As mentioned in my last blog post, I also thought about an alternative solution, i.e. to create a genuine plotting function for SourceTFR. But as I already suspected, this will not work without a lot of additional work. I originally intended to introduce a new type of plot derived from MNE's "TimeViewer", where you can not only skim along the time axis through the plotting GUI, but also along the frequency (and maybe the epochs) axis. After trying out some stuff, my best intuition to reaching this goal would be to simplify the "TimeViewer" class, and make it some kind of a "AxisViewer" class. This class would allow a developer to decide which axis (or even multiple axes) should be manipulable through the GUI. Yet, this would be only a part of the work, as this does not include the actual plotting function used by SourceTFR, and also would only work for the plots made on surface type source level data (since volume type source level data employs an entirely different plotting GUI). In my opinion, this functionality should rather be added later, so I can now concentrate on the finishing touches of the rest of the project. One such finishing touch is for example time and memory saving computation of tfr_stockwell, which is for now only available for tfr_morlet and tfr_multitaper. I already made attempts to tackle this problem, and currently try to make it pass the equivalence tests. But this will definitely be one of the things to do this week, as it will have big implications on the practical useability of the function.

PSF GSoC students blogs: 6th Last or Inception of new road Blog Post
2019-08-17 09:43:46
My best three months now come close to end but I am very happy from myself because I have completed my project before time. Upto this time my all project goals are completed i.e MVP, test and refactoring of code all of them is done. Just one pr regarding the reconnecting is on verge of merging which is a extended goals for the gsoc period. What I can say about past 3 months I don't have words to describe these days, I learned a lot of things like WebSocket, Gatsby and Jest. I spent entire time learning these technology and implementing them in my GatsbyJs preview project. Websocket for handling the websocket event fired from the backend of Plone CMS. Gatsby API, docs and gatsby-source-filesystem to learn how to implement the functionality for updating content on real time. Jest for writing test of implemented feature. I big thankyou to my mentor datakurre who helped me in completing the project. He was active throughout the project and solve my doubts regarding the project. He helped me out whenever I stuck at certain point. I learned a lot of things at the end of this program which is not avialable to most developer i.e refactoring the codebase. I have flatten the codebase by splitting the large function into the smaller ones. Out project contains a util.Js file which contains all the methods and function for the entire project. I refactored this utils file into small separate function file and now our codebase look neat, clean and enhanced code readability. Splitting into different files also helps us in refactoring the codebase from js to typescript which is our future plan. During the implementation I faced a interesting problem i.e how I grouped different functions into single file and separate those which is not related. I make a proper hierarchical order and resolve this issue.

TechBeamers Python: Python Filter()
2019-08-17 06:54:54
Python filter() function applies another function on a given iterable (List/String/Dictionary, etc.) to test which of its item to keep or discard. In simple words, it filters the ones that don’t pass the test and returns the rest as a filter object. The filter object is of the iterable type. It retains those elements which the function passed by returning True. We can also convert it to List or Tuple or other types using their factory functions. In this tutorial, you’ll learn how to use the filter() function with different types of sequences. Also, you can refer to the examples

In this tutorial, you’ll explore the difference between append and extend methods of Python List. Both these methods are used to manipulate the lists in their specific way. The append method adds a single or a group of items (sequence) as one element at the tail of a list. On the other hand, the extend method appends the input elements to the end as part of the original list. After reading the above description about append() and extend(), it may seem a bit confusing to you. So, we’ll explain each of these methods with examples and show the difference between

Systems are getting more complex as time goes by and this warrants the need to decouple systems more. A decoupled system is easier to build, extend, and maintain in the long run since not only does decoupling reduce the complexity of the system, each part of the system can be managed individually. Fault tolerance has also enhanced since, in a decoupled system, a failing component does not drag down the entire system with it.

TechBeamers Python: Python to Find Difference Between Two Lists
2019-08-06 17:15:30
In this tutorial, we’ll discover two Pythonic ways to find the Difference Between Two Lists. One of the methods is using the Python Set. It first converts the lists into sets and then gets the unique part out of that. Other non-set methods compare two lists element by element and collect the unique ones. We can implement these by using nested for loops and with the list comprehension. By the way, if you are not aware of the sets in Python, then follow the below tutorial. It would quickly introduce you to how Python implements the mathematical form of Set.

2019-08-06 05:05:31
Twitter is a popular social network that people use to communicate with each other. Python has several packages that you can use to interact with Twitter. These packages can be useful for creating Twitter bots or for downloading lots of data for offline analysis. One of the more popular Python Twitter packages is called Tweepy. You will learn how to use Tweepy with Twitter in this article.

Podcast.__init__: Build Your Own Knowledge Graph With Zincbase
2019-08-05 21:35:01
Computers are excellent at following detailed instructions, but they have no capacity for understanding the information that they work with. Knowledge graphs are a way to approximate that capability by building connections between elements of data that allow us to discover new connections among disparate information sources that were previously uknown. In our day-to-day work we encounter many instances of knowledge graphs, but building them has long been a difficult endeavor. In order to make this technology more accessible Tom Grek built Zincbase. In this episode he explains his motivations for starting the project, how he uses it in his daily work, and how you can use it to create your own knowledge engine and begin discovering new insights of your own.

Sumana Harihareswara - Cogito, Ergo Sumana: Kickoff for Communications Work on the Python 2 Sunsetting
2019-08-05 14:02:57
So the Python Software Foundation has contracted with my firm, Changeset Consulting, to help communicate about the sunsetting of Python 2. The high-level goal for Changeset's involvement is to help users through the end of the transition, help with communication so volunteers are not overwhelmed, and help update public-facing assets so core developers are not overwhelmed. During this project (starting now and going till the end of April 2020), Changeset's goals are: Create a concise page on python.org giving community guidance on the why and what of EOL Create and publicize a formal press release through the PSF Audit and update every mention of Python 2 on python.org, including in documentation and the wiki Develop a plan to handle redirecting https://docs.python.org/2/* (especially deep links) Publicize the new "what's up with EOL" page to a variety of audiences, respond to questions, and keep the page updated until PyCon US 2020 based on questions that come up So, towards those goals, you'll see me with my colleagues: Researching, writing, and editing technical documents and the press release Corresponding with stakeholders, writing and publishing announcements and other communications in multiple media Initiating and facilitating meetings (I will try to make them very minimal and short; if I invite you, please let me know your response) Filing, triaging, labelling, prioritizing, and linking issues, such as in the website repo For accountability, Changeset will provide reporting via: A publicly visible project roadmap, including milestones, probably within the pythondotorg repo A public rundown of all work completed at the end of each milestone, probably on the Discourse forum at discuss.python.org or on the pydotorg-www mailing list A brief written or oral monthly report to the Steering Council As necessary, updates to the PSF board If requested by PSF, blog posts monthly or more rarely, on the PSF blog or Python Insider (potentially) a PyCon North America birds-of-a-feather session in April 2020 I'm going to be asking for a lot of help along the way from the Python community: meeting with us, answering our questions, double-checking our drafts for accuracy, publicizing that EOL page to your circles, setting up some parties for January 1st. Thanks in advance and let's get the Python user base further along towards enjoying the shininess of Python 3.

PSF GSoC students blogs: Week #10
2019-08-04 23:47:59
I continued working on developing test cases. I tried to write up an overview for testing frameworks since such a framework could potentially be useful for other methods beyond PCA. I still haven't found a test where the implemented PCA falls short of the standard PCA, which is good in the sense that the performance is on par with the standard PCA but potentially harmful since we don't know its vulnerabilities. Meanwhile, I'm in the process of implementing NMF. I'm currently am trying to use the hyperbox method that I used in PCA. Unlike PCA, however, it is generally not possible to apply NMF in an incremental manner as we did in PCA so I'm reading up papers to resolve this issue.

PSF GSoC students blogs: Week #9
2019-08-04 23:43:07
I explored different ways in which PCA can be tested. More specifically, I tried to find some testing schemes under which the PCA I developed fails while the standard PCA method works. This practice is to help me understand the potential limitations of the PCA method. Unfortunately, I have yet to find a case where the PCA method fails. So far, it appears that the standard PCA and the implemented PCA performs more or less on the same level. Currently, I'm trying to exploit the fact that "hyperbox" method was used by drawing the loading matrix from different heavy tail distributions.

After familiarizing myself with the literature on the local scoring procedure, I coded it in the context of local models for MGWR. After multiple iterations, the model is converging and the bandwidth results are looking as expected. Though the parameter coefficients have values close to expected but not as accurate as needed. There could be possible issues with the weights associated in the model, and some adjustments need to be made for the coefficients which need to be figured out.

In this post, we are describing different ways to merge dictionaries in Python. There is no built-in method to combine them, but we can make some arrangements to do that. The few options that we’ll use are the dictionary’s update method and Python 3.5’s dictionary unpacking operator or also known as **kwargs. Some of the methods need a few lines of code to merge while one can combine the dictionaries in a single expression. Also, you need to be decisive in selecting which of the solution suits your condition the best. So, let’s now step up to see the different

Since we will load the data from blockchain once the user has pressed the load button, we can now safely ignore the data from the previous cryptocompare rest call.

Real Python: Understanding the Python Traceback
2019-07-29 14:00:00
Python prints a traceback when an exception is raised in your code. The traceback output can be a bit overwhelming if you’re seeing it for the first time or you don’t know what it’s telling you. But the Python traceback has a wealth of information that can help you diagnose and fix the reason for the exception being raised in your code. Understanding what information a Python traceback provides is vital to becoming a better Python programmer.

He also explains some of the security implications to be aware of and digs into ways that you can optimize your build process to cut down on wasted developer time. If you are using Docker, thinking about using it, or just heard of it recently then it is worth your time to listen and learn about some of the cases you might not have considered.

Hi and welcome again!

PSF GSoC students blogs: 4th Blog Post (During the second Period)
2019-07-28 20:30:07
So, what I have done in second period. For me the answer is very simple, MVP is completed in first phase which give me ample time to write test for the added feature and other function which is not tested earlier. In second Period I read lot of documentation of Jest. I have gone through each Matchers which is Provided by jest. Spent almost a week on reading it. After reading the documentation I feel very comfortable in writing test in jest. From my experience I would say don't dive in coding without knowing anything about the subject. First read the documentation of the following framework and become comfortable with the language. After that you will able to solve the problem in very less time. I have written around 10 test in this period which covers every aspect of the source code. I got stuck at the point where I have to write test for the generator function. I have to mock lot of data because It is the main function of source code which generates all the gatsby nodes initially. I also make some mistake. I am fetching data from the Plone CMS and then doing logging. I just forget that console log not print the nested array. So, I have made a huge mistake using console log. After lot of try I am not able to write test properly. I stuck in loop fixing one thing break another, after lot of afford I am able to solve this problem at 3am when I am going to bed after hectic day. I really enjoyed this phase a lot, I learned lot of new things and implemented it. I am very happy with myself what I am doing right now. In third phase I mainly write documentation and refactoring the code into small pieces of function so that It can enhance the  readability of code.

Hoorya!! I passed the second evaluation. In the evaluation week I mainly completed the only test which is left before the second evaluation i.e Adding test for the ploneGenerator method which generate all the Gatsby Node initially.  It is the most important generator function. I never tested the generator function in my life. I searched what is the best way to test the generator function and I found some response and successfully Send a pr for that. After that there is simple bug i.e Foreach array method randomly calling the api but we need syncrounus behaviour. After devoting one day and lot of thinking I found that only replacing the foreach method with for loop does the trick. Then I successfully created the pr for that also. You can see the pr link below.

PSF GSoC students blogs: Week 8
2019-07-26 19:37:07
Last week, I implemented multithread scanning with John's help. At first, I thought the logic was to create a function that instantiates a database everytime and close it finally, but that would also be too inefficient since it might take a long time to connect and disconnect the database if we let each thread call the function for each file. Instead, we could just use a queue to save all the files that will be scanned, and each thread just opens the database first and closes it only if there is no jobs to be done. We also don't need to take care of thread safety since the queue in Python is alread thread safe. Besides, I also added a flag to enable/disable the updating database so that users could save time to test or run the tool.

Stefan Behnel: Faster XML stream processing in Python
2019-07-26 15:36:08
It's been a while since I last wrote something about processing XML, specifically about finding something in XML. Recently, I read a blog post by Eli Bendersky about faster XML processing in Go, and he was comparing it to iterparse() in Python's ElementTree and lxml. Basically, all he said about lxml is that it performs more or less like ElementTree, so he concentrated on the latter (and on C and Go). That's not wrong to say, but it also doesn't help much. lxml has much more fine-grained tools for processing XML, so here's a reply.

Now, it was time for translating the lecture files and the assignments , which were in Portuguese, to Spanish. Initially, I had a major concern as I didn't know any of those languages, but finally I decided that I would take help of Google Translate and my intuition as much as I can to translate the files.

Just like v2 Onion services, we can also set up client authorization for Onion services v3. In simple terms, when you have a client authorization setup on an Onion service, only the Tor clients with the private token can access the service. Using this, you can run services (without opening up any port in your system) and only selected people can access that service, that is also being inside of totally encrypted Tor network. Last month, I did a workshop in Rootconf about the same topic, but, I demoed v2 Onion services. In this blog post, I am going to show you how you can do the same with the latest v3 services.

Last week, I was working on the parametrizing tests for SourceEstimates with tfr_morlet, and making sure the tests are also passed for all possible different functional arguments. Overall this worked quite smoothly for most parameters. In fact, I was already able to start implementing the same procedure for tfr_multitaper. Anyhow, for tfr_multitaper there is no reference function as for tfr_morlet, so tests for tfr_multitaper are for now basically just running the function and checking that everything is in the right place.

2019-07-22 17:11:41
For the most part, I spent time in reading about parallel Non-negative Matrix Factorization as this would most likely be the next course of action to take. Unlike PCA which had many scalable, parallel implementations available, NMF seems to be less well-studied and I could not find an implementation that would be suitable for reference. At the same time, I fixed some things and the performance time increased back to ~15 minutes. I also pushed a prototype jupyter notebook that replicates what the current PCA implementation in LiberTEM does, just with standard python libraries (e.g., sklearn, fbpca), and obtained satisfactory performance in reconstruction error. As per my mentor's suggestion, I will be looking into testing edge cases and if the current PCA works under these edge cases.

Sumana Harihareswara - Cogito, Ergo Sumana: Beautiful Soup is on Tidelift
2019-07-22 15:35:58
I've been doing a tiny bit of consulting for Tidelift for a little over a year now, mainly talking about them to open source maintainers in the Python world and vice versa. (See my October 2018 piece "Tidelift Is Paying Maintainers And, Potentially, Fixing the Economics of an Industry".) And lo, in my household, my spouse Leonard Richardson has signed up as a lifter for Beautiful Soup, his library that helps you with screen-scraping projects. Leonard writes: There was a period of about a year in 2017-2018 when I wasn't interested in doing Beautiful Soup work, but Tidelift changed that. Tidelift gathers subscription money from companies that rely on free software, and distributes the money to the developers in exchange for a level of support that I find sustainable. Nobody builds an entire product around Beautiful Soup (or at least nobody will admit do doing this), but thousands of people have used Beautiful Soup to save time at their day jobs. Bundling Beautiful Soup together with bigger projects like Flask and numpy is a solution that works really well for me. The other day I looked at the list of featured supported packages and was happy to see that a bunch of Python projects have signed up as lifters, including SciPy and numpy, Flask, setuptools, Werkzeug, websockets, urllib3, celery, coverage, a bunch of Django packages, Jinja2, keyring, Pylint, coverage, and pytest. And I think over the next 6-12 months we're going to see some effects of Tidelift support -- not just in the security and release cadences of the supported projects, but on other issues stemming from unfairness and a lack of reciprocity in open source, like maintainer burnout and expectation-setting. The list of licensing, security, maintenance, and marketing tasks lifters agree to do may end up being a benchmark, like the open source Independent Verification & Validation checklist by Open Tech Strategies, that even non-lifter maintainers use to set realistic expectations for what "supported"/"maintained" means.

Real Python: NumPy arange(): How to Use np.arange()
2019-07-22 14:00:00
NumPy is the fundamental Python library for numerical computing. Its most important type is an array type called ndarray. NumPy offers a lot of array creation routines for different circumstances. arange() is one such function based on numerical ranges. It’s often referred to as np.arange() because np is a widely used abbreviation for NumPy.

Since this is not thread-safe, the database might be locked.

PSF GSoC students blogs: Week 7
2019-07-19 02:08:48
This week I'm working on implementing mutithread extracting and scaning. So far the extracting works. From this week I acquired how does multithread pool work in Python. The pool has a method called `map`, which is basically same as `map` in Python: taking a function and an iterable as input, apply the function to the iterable in a multithread way. For extracting, this is easy to implement because we don't need to worry about thread-safe issue. However, for scanning, this could be a problem. We know that multiprocessing in operating system is really hard because we need to keep all processes/threads synchronized by using locks/mutex/semaphore. At first I thought this is okay because in scanning function we are supposed to just run mutiple queries at the same time, so we don't need lock.

Given a list of numbers, return a new list consists of the number which is larger than the sum of the remaining numbers in a list or larger than absolute zero. For example, this list [2, 5, 2, 1] will convert to [5, 2, 1] because 5 is greater than 2+1, 2 is greater than 1 and 1 is greater than absolute zero. Another example. [2, 3, -3] will convert to [2, 3] because 2 is greater than 3+(-3) and 3 is greater than -3 but -3 is lesser than 0 which means -3 will not get included into the new list.

2019-07-16 05:05:16
There are several Python code checkers available. For example, a lot of developers enjoy using Pylint or Flake8 to check their code for errors. These tools use static code analysis to check your code for bugs or naming issues. Flake8 will also check your code to see if you are adhering to PEP8, Python’s style guide.

PSF GSoC students blogs: Google Summer of Code with Nuitka 4th Weekly Check-in
2019-07-16 05:01:29
1. What did you do this week? This week, I worked on my script which automates the testing of nuitka-wheel pytest. Details can be found on my pull request: https://github.com/Nuitka/Nuitka/pull/440 Automated testing compares the pytest results of a nuitka wheel built using python setup.py bdist_nuitka to the uncompiled bdist_wheel pytest of each PyPI package. Testing is done to ensure that nuitka is building the wheel correctly. If the pytests pass/fail in the same way, that means Nuitka built the wheel properly. Else if the tests differ, then something is wrong. Virtualenv is used to create a clean environment with no outside pollution. I used subprocess to capture the output from terminal for comparison. I also implemented mechanics to ignore the time differences found in pytests. Furthermore, the testing has been extended to three more packages.

PSF GSoC students blogs: Coding week #7
2019-07-16 04:40:53
This week I debugged the issues being faced around the miscalculation of the three performance parameters (AIC, AICc and BIC) for the Poisson model. The parameters are as expected now and follow the expected trend. I also added other parameter checks to the Monte Carlo experiment (such as betas, performance parameters etc.). A complete notebook enlisting links to all the notebooks  within the Poisson MGWR model was made to make it easier to follow the completeness of the project. I am maintaining the Pull request for the simulated data example for Poisson MGWR and added the updated code to the PR (https://github.com/pysal/mgwr/pull/60 ).

TechBeamers Python: Python String Find()
2019-07-15 17:32:32
This tutorial explains Python string find() method that searches a substring and returns the index of its first occurrence. If not successful, then it returns the status as (-1). Let’s try to understand its usage with the help of simple examples. 1. Find() syntax 2. Find() with default values 3. Find() with multiple occurrences of substrings 4. Find() when no substrings exist 5. Find() with start and end indices Let’s now go through each of the section one by one. Python String Find() with Examples String’s find() is a built-in Python function that finds a substring into another string which

Building a Discord Chatbot with Giphy API

PSF GSoC students blogs: Week #7
2019-07-15 14:28:42
I managed to reduce the performance time to ~100 sec from 26 minutes by fetching a bigger chunk of data at a time than was fetched before. Furthermore, I successfully implemented hyperbox for loading matrix, which essentially is a method of subsampling from loading matrix so that the data is well-represented with less sample. Although more loss was induced by this, I'm inclined to conclude that the cost is manageable and the benefit in terms of speeding up the performance outweighs the cost. In fact, since I'm applying approximation PCA method, some degree of loss for this PCA is expected.

PSF GSoC students blogs: Optimizing "map" and "zip" - Weekly check in #4
2019-07-15 14:08:00
This week I started up with optimizing "map" built-in but later realised that I first need to optimize "zip" as there is no support on Nuitka for it as "map" is dependent on it. Initially I implemented the C backend for Python2 "zip" function but after discussing with my mentor we decided to keep only C backend for Python3 "zip" and depend on re-formulation for Python2 "zip" built-in.

PSF GSoC students blogs: For fork's sake - Fixing multiprocessing issues
2019-07-15 12:42:59
It was also reported that scipy.fft does not interact well with python's multiprocessing library. I was able to track down the issue and resolve it within a few hours, adding a unit test to ensure this wouldn't be broken again. However, when I went to update my uarray PR to use the new fast C++ version, the test started to fail. It turns out, the uarray multimethod objects needed to be pickleable in a very specific way that mimicks the behaviour of python Function types. Thankfully, after applying this fix the issue was resolved.

Podcast.__init__: A Modern Open Source Project Management Platform
2019-07-15 01:38:40
Project management is a discipline that has been through many incarnations, spawning an entire industry of businesses and tools. The challenge is to build a platform that is sufficiently powerful and adaptable to fit the workflow of your teams, while remaining opinionated enough to be useful. It also helps to have an open and extensible platform that can be customized as needed. In this episode Pablo Ruiz Múzquiz explains the motivation for creating the open source tool Taiga, how it compares to the other options in the market, and how you can use it for your own projects. He also discusses the challenges inherent to project management tools, his philosophies on what makes a project successful, and how to manage your team workflows to be most effective. It was helpful learning from Pablo’s long experience in the software industry and managing teams of various sizes.

Quansight Labs Blog: Ibis: Python data analysis productivity framework
2019-07-09 03:30:00
Ibis is a library pretty useful on data analysis tasks that provides a pandas-like API that allows operations like create filter, add columns, apply math operations etc in a lazy mode so all the operations are just registered in memory but not executed and when you want to get the result of the expression you created, Ibis compiles that and makes a request to the remote server (remote storage and execution systems like Hadoop components or SQL databases). Its goal is to simplify analytical workflows and make you more productive.

PSF GSoC students blogs: Seventh Week [July 1st - July 7th] [3rd PSF Blog Post]
2019-07-09 01:50:59
This session, we set up azure testing pipelines for "Carsus ... a TARDIS support package for creating and working with atomic datasets" (Carsus Documentation). This repository is intended to complement github.com/tardis-sn/tardis. The pipeline is much more advanced, as it runs 5 parallel tests, a simple basic pytest, one that uses remote data, one that runs slowly, one that fetches database info, and one that adds coverage results: Coverage results. (Hopefully we will get the covered files up to above 80 percent). We use pytest for these tests, and run the commands usings the Carsus setup module's arguments. I learned three new things about azure making this new pipeline. The first is how to efficiently use key value pairs to activate different environments for each test:

PSF GSoC students blogs: Improving uarray performance
2019-07-08 13:51:16
I have been focused on my uarray PR (uarray#1780). uarray defines a protocol for dispatching function calls to multiple different backend implentations. In my PR, I've been reimplementing the core function dispatch mechanism in C++ using the Python C-API. This week I've moved the backend registration system in to C++ which means the protocol is now 100% C++. This has brought the overhead down from ~5 us per function call to just ~700 ns or about 10 times more than a normal python function call. This overhead was one of the main blockers for the adoption of uarray so is very nice to see it come down.      I've also updated the vendored version pypocketfft in scipy#10393. This new version includes a small cache for the FFT "twiddle factors" which I helped implement. This improves benchmarks by ~20% in most cases or as much as 60% for some input sizes.

ListenData: Python list comprehension with Examples
2019-07-03 08:01:13
[i**3 for i in [1,2,3,4] if i>2] means take item one by one from list [1,2,3,4] iteratively and then check if it is greater than 2. If yes, it takes cube of it. Otherwise ignore the value if it is less than or equal to 2. Later it creates a list of cube of values 3 and 4. Output : [27, 64]List Comprehension vs. For Loop vs. Lambda + map()All these three have different programming styles of iterating through each element of list but they serve the same purpose or return the same output. There are some differences between them as shown below. 1. List comprehension is more readable than For Loop and Lambda function.List Comprehension[i**2 for i in range(2,10)]For Loopsqr = [] for i in range(2,10): sqr.append(i**2)sqrLambda + Maplist(map(lambda i: i**2, range(2, 10)))Output[4, 9, 16, 25, 36, 49, 64, 81]List comprehension is performing a loop operation and then combines items to a list in just a single line of code. It is more understandable and clearer than for loop and lambda. range(2,10) returns 2 through 9 (excluding 10).**2 refers to square (number raised to power of 2). sqr = [] creates empty list. append( ) function stores output of each repetition of sequence (i.e. square value) in for loop.map( ) applies the lambda function to each item of iterable (list). Wrap it in list( ) to generate list as output

IslandT: Create a Python function to compare the end string
2019-06-30 13:40:30
Hello friend, we will start a new Python project in the next chapter but before that let us solve another Python problem first in this article. This is one of the questions in codewars which I have solved today : Given a string and an end string, compare the end string part with the end part of the given string, if they match each other, then return true, otherwise return false. For example, if the given string is “Hello” and the end string is “ello” then the function will return true. If the given string is “World” and the end string is “rld!” the the function will return false.

IslandT: Return the highest volume of traffic during peak hour
2019-06-29 09:02:40
In this article, we are going to create a function which will return a list of tuples that consist of a particular hour and the highest traffic volume for that particular hour. The stat has been taken every 10 minutes in each hour. For example, at 4.00pm the total numbers of traffics that pass through a junction for every 10 minutes are as follows: [23, 22, 45, 66, 54, 33]. The traffic volume measurement in this example will begin at 4.00pm and end at 8.00pm. Below is the solution to this problem.

IslandT: Python is still not there yet
2019-06-26 05:40:33
I have been blogging about Python programming language for a while since 2017, the reason which I continue to write about this programing language is due to the popularity of this language in the programming languages world! At the moment Python is ranked mostly in the top three positions beginning at 2019 at both TIOBE Index and The PYPL PopularitY of Programming Language Index. Those impressive statistic figures from the above sites certainly suggest that Python is already the world number 1, and indeed there are a few reasons that will further solidify that claim. 1) The uncertainty of Java, which now requires the Java developer to pay for using the Java programming language. My Java knowledge has been stopped at Java 7 and goes no further than that because I simply can’t afford to pay such an expensive amount of fees just to use Java to create a free application or game for the computer users. Recently I have started to pick up Kotlin which is based on Java just in case I can’t use Java to develop Android application anymore without paying a fee in the future, but will Java ask for the fee from the Kotlin developer in the future as well? I have a feeling that the Android OS will see more issues in the near future. 2) The future of the C series languages depends on the windows application developer as well as the game developer. Just like Java, C type of programming language can run in all OS, ranging from Linux to Mac to Windows. But I have spotted 2 problems for series C, 1) for a game developer who uses the famous game engines such as Unity or Unreal, it will usually take a very long time to compile his c# or c++ programming code even with just a small changes, for those of you who have used C# to develop your Unity game before, how long will it takes for the Unity engine to recompile the C# code even just for a very small changes in your game code before you can see your game in action? After a few times using Unity to develop the game, I have now switched to Godot where the compile time is indeed very fast as compared to Unity. 2) pointer is not a good idea in c++, even the experienced programmer will make a silly mistake by pointing a variable to one of the rubbish address, c++ is the world most difficult to debug programming language, it is really hard for me to spot the bug within the c++ program because sometime the bug will not appear during the compilation time. So there you have it, with Java and the series C out of the path, Python is now ready to become the world number 1. All the Python supporters certainly will be very happy about that after they have spent thousands of hour learning and creating an application for Python and now it is time to harvest their Soya Bean! But not too fast, because I think there are a few areas Python still needs to improve before Python can rule the world! Here are those parts that I think Python.org needs to work on if it really has the ambition to become world number 1!

IslandT: Find the smallest number within a list with python
2019-06-24 10:31:46
In this example, we will create a python function which will take in a list of numbers and then return the smallest value. The solution to this problem is first to create a place holder for the first number within the list, then compares that number with other numbers within the same list in the loop. If the program found a number which is smaller than the one in the place holder, then the smaller number will be assigned to that place holder.

Caktus Consulting Group: How to Set Up a Centralized Log Server with rsyslog
2019-06-20 12:00:00
For many years, we've been running an ELK (Elasticsearch, Logstash, Kibana) stack for centralized logging. We have a specific project that requires on-premise infrastructure, so sending logs off-site to a hosted solution was not an option. Over time, however, the maintenance requirements of this self-maintained ELK stack were staggering. Filebeat, for example, filled up all the disks on all the servers in a matter of hours, not once, but twice (and for different reasons) when it could not reach its Logstash/Elasticsearch endpoint. Metricbeat suffered from a similar issue: It used far too much disk space relative to the value provided in its Elasticsearch indices. And while provisioning a self-hosted ELK stack has gotten easier over the years, it's still a lengthy process, which requires extra care anytime an upgrade is needed. Are these problems solvable? Yes. But for our needs, a simpler solution was needed.

Reuven Lerner: Variables are pronouns: A simple metaphor for Python newbies
2019-06-10 13:33:32
I teach about 10 different courses to companies around the world, but my favorite remains “Python for non-programmers.” Participants in this course are typically network and system administrators, support engineers, and managers who want to learn some programming skills, but don’t see themselves as programmers. Moreover, many of them took a programming course back when they were university students, and were so horrified, overwhelmed, and frustrated that they gave up. Perhaps they’re still working for a high-tech company, but they have tried to avoid programming.

Podcast.__init__: Web Application Development Entirely In Python
2019-06-10 03:13:27
The knowledge and effort required for building a fully functional web application has grown at an accelerated rate over the past several years. This introduces a barrier to entry that excludes large numbers of people who could otherwise be producing valuable and interesting services. To make the onramp easier Meredydd Luff and Ian Davies created Anvil, a platform for full stack web development in pure Python. In this episode Meredydd explains how the Anvil platform is built and how you can use it to build and deploy your own projects. He also shares some examples of people who were able to create profitable businesses themselves because of the reduced complexity. It was interesting to get Meredydd’s perspective on the state of the industry for web development and hear his vision of how Anvil is working to make it available for everyone.

2019-06-04 13:19:00
In Python, a module is a self-contained file with Python statements and definitions. For example, file.py, can be considered a module named file. This differs from a package in that a package is a collection of modules in directories that give structure and hierarchy to the modules.

Brett Cannon: The challenges in designing a library for PEP 425 (aka wheel tags)
2019-06-02 04:11:14
If you have  ever looked at a project that has a lot of wheels (like numpy), you may have wondered what the part that comes after the project name and version mean. Well, they are known as platform compatibility tags and they are primarily defined in PEP 425. For someone like me whose personal projects are all written in pure Python, I never really paid much thought to what those tags meant since the wheel tags for my projects are all py3-none-any (you will find out what that means later in this post). So what led me from not caring to learning as much as I could about wheel tags and what did I learn along the way?

Quansight Labs Blog: metadsl: A Framework for Domain Specific Languages in Python
2019-05-31 05:00:00
Hello, my name is Saul Shanabrook and for the past year or so I have been at Quansight exploring the array computing ecosystem. This started with working on the xnd project, a set of low level primitives to help build cross platform NumPy-like APIs, and then started exploring Lenore Mullin's work on a mathematics of arrays. After spending quite a bit of time working on an integrated solution built on these concepts, I decided to step back to try to generalize and simplify the core concepts. The trickiest part was not actually compiling mathematical descriptions of array operations in Python, but figuring out how to make it useful to existing users. To do this, we need to meet users where they are at, which is with the APIs they are already familiar with, like numpy. The goal of metadsl is to make it easier to tackle parts of this problem seperately so that we can collaborate on tackling it together.

Podcast.__init__: Hardware Hacking Made Easy With CircuitPython
2019-05-20 02:29:49
Learning to program can be a frustrating process, because even the simplest code relies on a complex stack of other moving pieces to function. When working with a microcontroller you are in full control of everything so there are fewer concepts that need to be understood in order to build a functioning project. CircuitPython is a platform for beginner developers that provides easy to use abstractions for working with hardware devices. In this episode Scott Shawcroft explains how the project got started, how it relates to MicroPython, some of the cool ways that it is being used, and how you can get started with it today. If you are interested in playing with low cost devices without having to learn and use C then give this a listen and start tinkering!

Peter Bengtsson: How I simulate a CDN with Nginx
2019-05-15 18:08:46
Usually, a CDN is just a cache you put in front of a dynamic website. You set up the CDN to be the first server your clients get data from, the CDN quickly decides if it was a copy cached or otherwise it asks the origin server for a fresh copy. So far so good, but if you really care about squeezing that extra performance out you need to worry about having a decent TTL and as soon as you make the TTL more than a couple of minutes you need to think about cache invalidation. You also need to worry about preventing certain endpoints from ever getting caught in the CDN which could be very bad.

Game of Thrones is arguably one of the biggest pop culture phenomena to hit the public consciousness in the last decade. Since the hype for the final season's arrival has gone down a bit, especially mine after episode three , I thought I could use this time to finally explore a side of Data Science that has always intrigued me - Network Theory, and combine it with a topic I am very invested in - Game of Thrones. Just to be clear I won't be making any claims or predictions about the plot of the show - No Spoilers. I just want to use Game of Thrones as a hopefully relatable context for discussing the analysis techniques.

If you’re segmenting a handful of images by color or detecting faces one by one using OpenCV, then you don’t need to worry about it. Even if you’re using the Python Imaging Library (PIL) to draw on a few hundred photos, you still don’t need to. Storing images on disk, as .png or .jpg files, is both suitable and appropriate.

Stack Abuse: Working with PDFs in Python: Adding Images and Watermarks
2019-05-14 13:26:00
Today, a world without the Portable Document Format (PDF) seems to be unthinkable. It has become one of the most commonly used data formats ever. Up to PDF version 1.4, displaying a PDF document in an according PDF viewer works fine. Unfortunately, the features from the newer PDF revisions, such as forms, are tricky to implement, and still require further work to be fully functional in the tools.

Podcast.__init__: Building A Privacy Preserving Voice Assistant
2019-05-13 02:28:24
Being able to control a computer with your voice has rapidly moved from science fiction to science fact. Unfortunately, the majority of platforms that have been made available to consumers are controlled by large organizations with little incentive to respect users’ privacy. The team at Snips are building a platform that runs entirely off-line and on-device so that your information is always in your control. In this episode Adrien Ball explains how the Snips architecture works, the challenges of building a speech recognition and natural language understanding toolchain that works on limited resources, and how they are tackling issues around usability for casual consumers. If you have been interested in taking advantage of personal voice assistants, but wary of using commercially available options, this is definitely worth a listen.

Quansight Labs Blog: MOA: a theory for composable and verifiable tensor computations
2019-04-17 05:00:00
Python-moa (mathematics of arrays) is an approach to a high level tensor compiler that is based on the work of Lenore Mullins and her dissertation. A high level compiler is necessary because there are many optimizations that a low level compiler such as gcc will miss. It is trying to solve many of the same problems as other technologies such as the taco compiler and the xla compiler. However, it takes a much different approach than others guided by the following principles.

Sumana Harihareswara - Cogito, Ergo Sumana: PyCon NA, !!Con, and WisCon
2019-04-16 18:36:55
I'll start the month at PyCon North America in Cleveland, Ohio, practically the whole conference, 1-9 May. I'm co-organizing The Art of Python, an arts festival -- several short plays, plus a fanvid and live music -- the night of Friday, May 3rd. And during the sprints, 6-9 May, I'll be concentrating on the world of Python packaging and distribution, e.g., PyPI. I'll go home to New York City, then go to !!Con 11-12 May, where I am not organizing or speaking or suchlike. And then I'll be at WisCon in Madison, Wisconsin, for the whole convention, 24-27 May plus a little extra on either side. I will once again be the comedy auctioneer for the auction on Saturday night that benefits the Tiptree Award -- if you have something to donate to the auction, please let us know by 15 May. I may not make it to the Floomp or the vid party. I will probably be on a few panels; several panels are still seeking volunteer panellists (sign up by 19 April). I do plan to be at the Gathering and the Dessert Salon (heads-up, changes to Dessert Salon entry flow). If you're going to be at any of these events, perhaps we can share a beverage! If you want to make sure that we do that, let's actually set up at least a tentative appointment soon, so I can put it in my calendar. I will be more responsive to emails and text messages than to social media while at these conferences, and in particular, I may see mentions and direct messages on Mastodon but I probably won't see mentions or direct messages on Twitter. Also, I am pretty forgiving about being called mispronunciations of my name, but here's a recording in case you want help -- I also respond to "Vikki" which is the fake name I use with strangers at restaurants. And I will probably not hug you unless we know each other well.

codingdirectional: A Rule of Divisibility by 7
2019-04-16 10:06:18
A number m of the form 10x + y is divisible by 7 if and only if x − 2y is divisible by 7. In other words, subtract twice the last digit from the number formed by the remaining digits. Continue to do this until a number known to be divisible or not by 7 is obtained; you can stop when this number has at most 2 digits because you are supposed to know if a number of at most 2 digits is divisible by 7 or not.

Podcast.__init__: Exploring Python's Internals By Rewriting Them In Rust
2019-04-15 17:46:58
The CPython interpreter has been the primary implementation of the Python runtime for over 20 years. In that time other options have been made available for different use cases. The most recent entry to that list is RustPython, written in the memory safe language Rust. One of the added benefits is the option to compile to WebAssembly, offering a browser-native Python runtime. In this episode core maintainers Windel Bouwman and Adam Kelly explain how the project got started, their experience working on it, and the plans for the future. Definitely worth a listen if you are curious about the inner workings of Python and how you can get involved in a relatively new project that is contributing to new options for running your code.

Stack Abuse: Introduction to the Python lxml Library
2019-04-10 16:17:25
lxml is a Python library which allows for easy handling of XML and HTML files, and can also be used for web scraping. There are a lot of off-the-shelf XML parsers out there, but for better results, developers sometimes prefer to write their own XML and HTML parsers. This is when the lxml library comes to play. The key benefits of this library are that it's ease of use, extremely fast when parsing large documents, very well documented, and provides easy conversion of data to Python data types, resulting in easier file manipulation.

Podcast.__init__: Version Control For Your Machine Learning Projects
2019-04-08 10:35:04
Version control has become table stakes for any software team, but for machine learning projects there has been no good answer for tracking all of the data that goes into building and training models, and the output of the models themselves. To address that need Dmitry Petrov built the Data Version Control project known as DVC. In this episode he explains how it simplifies communication between data scientists, reduces duplicated effort, and simplifies concerns around reproducing and rebuilding models at different stages of the projects lifecycle. If you work as part of a team that is building machine learning models or other data intensive analysis then make sure to give this a listen and then start using DVC today.

Just got back from my first trip in my Tesla Model 3. I was a bit nervous, but mostly because my first trip also included my in-laws riding with us. I get along with them great but I knew if the car became a burden during the trip, it wouldn’t just be me affected or me and my wife, but all of us. Two of which didn’t care about the mission or vision of electric vehicles; they just wanna go on vacation and have fun. (to be fair… so did I.) We went from our home to Gatlinburg and back. It’s right at 239 miles one way with a rough overall elevation change of 917ft.

leftmouseclickin: Plot the Aroon Oscillator values with python
2019-03-25 12:39:23
Welcome to the ongoing Forex and Stock python project. In this chapter we will create a method to plot the Aroon Oscillator values with python. The Aroon Oscillator is a line that can fall between -100 and 100. A high Oscillator value is an indication of an uptrend while a low Oscillator value is an indication of a downtrend. When Aroon Up remains high from consecutive new highs, the Oscillator value will be high, following the uptrend. Below is the revised version of the project, we have created a method to plot the Aroon Oscillator values and of course a button which will call that method.

The Average Directional Movement Index Rating (ADXR) measures the strength of the Average Directional Movement Index (ADX).

The sports.py module does not have a method to only return the live NBA matches but instead that API call will return basically all the live basketball matches from all the basketball leagues around the world. Therefore we will need to filter out all those none NBA results before showing the data on the text widget. Below is the modified version of the program which will do just that. We will perform the filtering process under the get matches method.

Test and Code: 68: test &amp;&amp; commit || revert (TCR) - Thomas Deniffel
2019-03-13 04:45:00
With conventional TDD, you write a failing test, get it to pass, then refactor. Then run the tests again to make sure your refactoring didn't break anything. But what if it did break something? Kent Beck has been recommending to commit your code to revision control after every green test run. Oddmund Strømme suggested a symmetrical idea to go ahead and revert the code when a test fails. Kent writes that he hated the idea, but had to try it. Then wrote about it last September. And now we have TCR, "(test && commit) || revert".

I will just use one of the random stock to show the example and will further modify this feature in the next chapter where a user will be able to select any major stock that he wishes from the combo box to retrieve it’s valued and then the program will plot the value vs the time graph accordingly. Here is the modified version of the python program.

It should be noted that No Starch did not ask me to do a book review. They only wanted me to do a technical review for them before the book was published.

Stack Abuse: Introduction to Python Decorators
2019-03-05 15:15:52
In Python, a decorator is a design pattern that we can use to add new functionality to an already existing object without the need to modify its structure. A decorator should be called directly before the function that is to be extended. With decorators, you can modify the functionality of a method, a function, or a class dynamically without directly using subclasses. This is a good idea when you want to extend the functionality of a function that you don't want to directly modify. Decorator patterns can be implemented everywhere, but Python provides more expressive syntax and features for that.

I myself is a tech and programming lover and I like to play with new tech stuff and create cool software to use in every day life. Although all the above statements are true there is one thing we all need to know which is although I can always provide free code for the readers but I do need to pay rent for this website every month, thus I would like to take this opportunity to ask for your kind donation to help this site out, the donation form is located at the sidebar of this website, I really don’t mind how much money you donate to me, 1 usd is as good as 100 USD as long as there is enough money to finance this website to keep it going. So friend, kindly provide your support to me through donation, thank you in advance. Alright, without wasting anymore time, let us begin this new chapter.

gamingdirectional: The mana detection mechanism
2019-02-28 07:04:26
Finally, in this chapter, we will look at the mana detection mechanism where when the player has overlapped mana he will gain 1 unit of life so when he hits the enemy he can continue to move onward after he has used that 1 unit of life to heal himself. We will also remove the enemy from the scene after it has collided with the player. In order to create such a system, we need to edit a few files.

Mike Driscoll: How I Write Books about Python
2019-02-26 13:30:47
I get asked questions about my book writing process from time to time and I have been meaning to write about this topic for a while. The main reason I wrote my first book, Python 101, was because of the readers on my blog. They had been encouraging me to write a book on wxPython for a while and I decided that I should start by writing an introductory book so I wouldn’t need to include a bunch of introductory information in my intermediate level book if I ever got around to writing it.

codingdirectional: Continue developing the currency exchange application
2019-02-26 12:33:21
Hi, after deep thought I have decided to continue developing the currency exchange application which I have created in the previous chapter and make it a standalone python application. In the previous chapter, we had created a simple interface which will display all the usd/world currencies exchange rate in a tkinter label which we will further modify this interface and make it displays the other currency pair as well as we progress, but before we go even further we do need to convert the currency ID to their real name first, for example, it is very hard for the first timer to know which currency is this by just look at its ID : CAD, if we can convert the ID to the name of that currency then it will be better, for example, CAD = Canadian Dollar. In this chapter, we will just go to make an API call for the ID and the name of all the available currencies and print them out under the console.

codingdirectional: Find the currency exchange rate with python
2019-02-25 07:23:00
Hello and welcome back, in this chapter we are going to continue developing our cryptocurrency application with the help of coinbase api and the tkinter module. Before we go even further on cryptocurrency we will look at another great api offered by coinbase, the usd/world currency exchange rate api. We will create a new tkinter interface and display all those exchange rates with the help of the Text and Label widget. It seems like at the moment the free API only offers the USD/ world currency pair but there is no problem for us to find the other currency pair with just a little math. In this chapter, we will find the exchange rate for usd/all world currency pairs and display them on the label part of the tkinter user interface.

Stefan Behnel: Speeding up basic object operations in Cython
2019-02-17 18:24:48
Raymond Hettinger published a nice little micro-benchmark script for comparing basic operations like attribute or item access in CPython and comparing the performance across Python versions. Unsurprisingly, Cython performs quite well in comparison to the latest CPython 3.8-pre development version, executing most operations 30-50% faster. But the script allowed me to tune some more performance out of certain less well performing operations. The timings are shown below, first those for CPython 3.8-pre as a baseline, then (for comparison) the Cython timings with all optimisations disabled that can be controlled by C macros (gcc -DCYTHON_...=0), the normal (optimised) Cython timings, and the now improved version at the end.

Talk Python to Me: #199 Automate all the things with Python at Zapier
2019-02-14 08:00:00
Do your applications call a lot of APIs? Maybe you have a bunch of microservices driving your app. You probably don't have the crazy combinatorial explosion that Zapier does for connecting APIs! They have millions of users automating things with 1,000s of APIs. It's pretty crazy. And they are doing it all with Python. Join me and Bryan Helmig, the CTO and co-founder of Zapier as we discuss how they pull this off with Python.

Kushal Das: Tracking my phone's silent connections

My phone has more friends than me. It talks to more peers (computers) than the number of human beings I talk on an average. In this age of smartphones and mobile apps for A-Z things, we are dependent on these technologies. However, at the same time, we don’t know much of what is going on in the computers equipped with powerful cameras, GPS device, microphone we are carrying all the time. All these apps are talking to their respective servers (or can we call them masters?), but, there is no easy way to track them.

codingdirectional: Return the list of the number and its power with python
2019-02-12 04:15:11
Before we start our new python project here is another solution for one of the python’s question on codewars. In this example, we need to create a method which will accept a number and returns a list consists of a pair of a number and power that are equal to that input number. For example, the input number is 9, then the number and it’s power which is equals to that input number is [3, 2] because 3 * 3 = 9. If there is no number and power that match the input value then None will be returned. Here is the solution to the above mentioned question.

Podcast.__init__: Computational Musicology For Python Programmers
2019-02-11 19:25:22
Music is a part of every culture around the world and throughout history. Musicology is the study of that music from a structural and sociological perspective. Traditionally this research has been done in a manual and painstaking manner, but the advent of the computer age has enabled an increase of many orders of magnitude in the scope and scale of analysis that we can perform. The music21 project is a Python library for computer aided musicology that is written and used by MIT professor Michael Scott Cuthbert. In this episode he explains how the project was started, how he is using it personally, professionally, and in his lectures, as well as how you can use it for your own exploration of musical analysis.

Anwesha Das: Have a safer internet
2019-02-05 17:40:35
Today, 5th February is the [safer internet day](https://www.saferinternetday.org/).   The primary aim of this day is to advance the safe and positive use of digital technology for children and young people. Moreover, it promotes the conversation over this issue. So let us discuss a few ideas.The digital medium is the place where we live our today. It has become our world. However, as compare to the physical world to this world and its rules are unfamiliar to us. Also, adding to that with the advent of social media we are putting our lives, every detail of it in and at the domain of social media. We are then letting governments, industrial lords, political parties, snoops, and the society to judge, to see and monitor us. We, the fragile, vulnerable us, do not have any other option but to watch our freedom, privacy vanishing. However, do we not have anything to save ourselves? Some basic ideas are the following which you can try to use in everyday computer/phone life:### Use unique passphrases Use passphrases instead of passwords. Passwords are easy to break as well as easy to copy so instead of using “Frank” (a name) or “Achinpur60”(a part of your address), use passphrases like “DiscountDangerDumpster”. It is easy to remember and hard to break. You can assemble 2 more languages (it is easy for us, Indians, right?). I used diceware to generate that password. Moreover, by unique what I mean is that do not use the SAME PASSWORD EVERYWHERE.  I can feel how difficult, tedious, impossible it is for you to remember all the lengthy, difficult passphrases (now not passwords remember!) for all your accounts. However, nothing can be done with this. If someone can get your passphrase for one account, he will be able to all of them.  Unique passphrases help a lot in this case.

A prime number is a number which can only be divided by one and itself. 1 is not a prime number. The below program will add one to the sum of all the numbers within a list until it reaches the closest prime number from that total, it then will return the value which needs to be added to reach that prime status.

As a developer and user of open source code, you interact with software and digital media every day. What is often overlooked are the rights and responsibilities conveyed by the intellectual property that is implicit in all creative works. Software licenses are a complicated legal domain in their own right, and they can often conflict with each other when you factor in the web of dependencies that your project relies on. In this episode Luis Villa, Co-Founder of Tidelift, explains the catagories of software licenses, how to select the right one for your project, and what to be aware of when you contribute to someone else’s code.

Real Python: Working With Files in Python
2019-01-21 06:00:00
Python has several built-in modules and functions for handling files. These functions are spread out over several modules such as os, os.path, shutil, and pathlib, to name a few. This article gathers in one place many of the functions you need to know in order to perform the most common operations on files in Python.

codingdirectional: Further modifying the video editing application
2019-01-21 04:58:01
Our video editing application project is nearly completed so then let us continue to modify it in this post. In this new code edition we will include the repeat scale box which allows the user to select how many times he wishes the video to repeat, the fps scale box which allows the user to select the fps for the new video, besides that we have also included the video format combo box where the user can select which new video format he wishes his new video to have. Below is the entire program.

Toshio Kuratomi: Optimizating Conway
2019-01-20 22:42:03
Conway’s Game of Life seems to be a common programming exercise. I had to program it in Pascal when in High School and in C in an intro college programming course. I remember in college, since I had already programmed it before, that I wanted to optimize the algorithm. However, a combination of writing in C and having only a week to work on it didn’t leave me with enough time to implement anything fancy.

2019-01-19 06:03:14
Hello and welcome back, it has been a day since the last post and today we will continue to edit our video application project. After I have included the final feature for this project I can now concentrate on the user interface part. Mine ideology is always to focus on the main objective first before working on the small details when it comes to programming, as long as we have destroyed the main battleship then it will easy to take on those small battleships that have lost their main supply line.

Stack Abuse: Lambda Functions in Python
2019-01-18 14:10:00
In Python, we use the lambda keyword to declare an anonymous function, which is why we refer to them as "lambda functions". An anonymous function refers to a function declared with no name. Although syntactically they look different, lambda functions behave in the same way as regular functions that are declared using the def keyword. The following are the characteristics of Python lambda functions:

Hello, and well come back. In this article, we will input the last feature for our video editing application before we tidy up the entire application’s user interface and then upload this free application to the online software store for others to enjoy. As usual, we will use the FFmpeg tool together with a python program to convert a video from the mp4 format to the webm format. This program will first resize the video to the size which the user has selected and then start to convert the video to the new format then saves that new video to a new file. Below is the entire program.

I did a couple of views and a couple of templates. It seems to be working well.

Djangostars: Top Seven Apps Built With Python
2019-01-14 12:57:09
Over its almost 30 years of existence, Python has become one of the most popular programming languages. But if most startups once used it because of its simplicity and low cost, modern giants like Instagram or Spotify use Python and the Django framework to create smooth working experiences. Famously, Django provides fast work processes, clean design, and transparent functionality, among many other advantages. It allows developers at all levels to focus on writing their apps instead of reinventing the wheel (or fixing it, for that matter). On top of that, it’s free, open source, and has gathered a mighty community of developers over the years. Large companies appreciate this. To give you an example, let’s take a look at some apps written in Python that you probably didn’t know about.

2019-01-13 03:55:34
Hello, in this article we will continue to develop the video editing application which we have started a while ago. In this article, we will create an animated gif from a video, due to the size of the gif file which can get very large we will trim the duration of the video in this example by providing the starting time of that video which is very near to the end time of that video. We will hard code the video’s starting time in this example but we will retrieve the duration of the video in the next chapter so we do not need to worry about the overflow of the video’s starting time issue from any video. Just like before we will use both python and FFmpeg tool to create the animated gif from a video based on the video’s starting time to the video’s end time.

But despite the role, location data makes the use of service more user-oriented and, by that mean, more convenient.

2019-01-08 05:56:46
Hello, today I have almost completed all the basic questions on py.checkio.org and are ready to move into the real game logic programming. One of the questions I have solved today is the question which asks us to find out the angle of the sun based on the position of the clock. For example, 12.pm noon means 90 degrees, 6.00 am morning means 0 degrees and we will not see the sun after 6.00pm and before 6.00 am. We need to create a python function which will take in a time string and then return the angle of the sun based on the position of the clock. If we do not see the sun yet then just return a text telling the user about that. After a simple calculation, we know that the angle between each of the two subsequent hours is 15 degrees. Here is what the sun angle looks like from a simple sketch.

Ian Ozsvald: Looking back on 2018, looking to 2019
2019-01-07 19:28:49
So last year was a damned hard year – ignoring Brexit and other international foolishness, on a personal level (without going in to details) by mid-year I was emotionally wiped out. A collection of health issues between family and friends kept rearing their ugly heads and over time I ran very low of emotionally supportive energy to share. Our not-so-old cat suddenly dying of kidney failure just about topped the year off. Thankfully by Christmas most of the health issues had sorted themselves out, massively reducing their induced stress.

2019-01-07 12:38:15
Hello again, today let us continue to explore the question on the previous website which allows us to develop a game with python. In this chapter, we are going to create a function which will encrypt the text passes in as the first argument based on the integer passed in as the second argument to that same function. This function will only accept the lowercase character from a-z and the empty space. What this function does is to add up the character code of an a-z character with the second argument of that function to produce a new character and finally return the entire new text based upon this encrypt method.

The project which we are going to create together is the video editing/streaming application project written in python with the help of the ffmpeg multimedia framework. I am going to create the project in windows os but if you are the mac or Linux user then you can just slightly modify the program code to suit your need, no problem at all.

One of the most "obscure" features of Python that almost all Python programmers use, even the beginner ones, but don't really understand, is context managers. You've probably seen them in the form of with statements, usually first encountered when you learn opening files in Python.

So without further ado, let's dive into it!

After solving this question I think I will create a tic tac toe game with python later on since I already have the solution for the game mechanism so better don’t waste this wonderful resource! Below is the entire solution to the above tic tac toe question. I have thought of making the solution shorter by introducing a few functions to replace the long solution but for now, we will stick to this one.

Stack Abuse: Intro to the Python Random Module
2018-12-24 14:01:00
Even for someone not interested in computer programming, the usefulness of generating random numbers in certain circumstances is something obvious. In most board games we throw dice to generate an unpredictable number that defines the player's next move. Also, we can all agree that playing any card game would be pointless without a proper shuffle between rounds.

Ned Batchelder: A thing I learned about Python recursion
2018-12-21 01:40:25
Working on a programming challenge, I was surprised by something. I built a tree structure with a recursive function. Then I tried to use a recursive function to sum up some values across the tree, and was met with a RecursionError. How could I have enough stack depth to build the tree, but not enough to then sum up its values?

Mahmoud Hashemi: Awesome Python Applications
2018-12-20 19:20:00
What we can learn from 180+ case studies on successfully shipping Python software. If you're reading this (or hearing this), you read and write code, probably Python. And for all the code you've shipped, you've probably had your share of missed requirements. Somehere in the excitement of software abstraction, we can lose sight of what really matters, what makes our well-factored modules and packages and frameworks turn into real-world applications. That's why I'm pleased to announce Awesome Python Applications, a hand-curated list of 180+ projects, all of which are: Free software with an online source repository. Using Python for a considerable part of their functionality. Well-known, or at least prominently used in an identifiable niche. Maintained or otherwise demonstrably still functional on relevant platforms. Shipped applications, not libraries or frameworks. The result is a list of predominantly focused on software that installs without pip or PyPI, and whose audience is mostly not developers. There's still plenty of that in there, too, with other exceptions, but the breadth of the list speaks for itself. So why spend weeks cataloguing open-source Python applications? Aside from holiday cheer, three big reasons. ContentsGoal #1: A Better Development CycleGoal #2: A More Complete Python Production LoopGoal #3: Grounding for the Python EcosystemNext stepsGoal #1: A Better Development Cycle Ever since I started talking about Python packaging, people have been asking me questions about which packaging technique is best for their software. I was struck, over and over again, how far people can get in developing an application before reaching the fundamental question of delivery. Exploring this, I landed on a more basic question: Why are so many people building applications from first principles (blog posts and Stack Overflow)? Isn't Python one of the biggest names in the software world? Aren't there dozens of successful, real-world applications written in Python? What are the chances your application is totally unique? So Awesome Python Applications is really an attempt to open up a new flow for answering tough development questions. When building an application, scan the list to find projects which most closely match your project's requirements. Then, use that application as a guide for answering your own questions. This works especially well for abstract questions surrounding architecture, deployment, and testing. Back in school, I learned more about architecture and software development from the MediaWiki source code than I did from any class. It continues to inspire me to this day. APA is the next step in enabling the holistic education of a working application with real users. In short, while we may lack the time to write them, each production application is worth a thousand blog posts. Goal #2: A More Complete Python Production Loop We Python programmers are also software users. But unlike other software users, we know how to file issues and may even make significant contributions back to our applications of choice. By choosing Python software when possible, we take one step closer to pitching in. What better way for a future application developer to get started? I would love to see more developers connect with software they didn't realize was Python. My (minor) contributions to the Twisted were greatly energized by the knowledge that one of my favorite applications, Deluge, heavily used the library. Using free software leads to creating more free software. Goal #3: Grounding for the Python Ecosystem With the pace and cerebrality of technology, it can be easy to get ahead of ourselves and our end users. Infrastructure devs get disconnected from application devs, and that makes for worse software over time. This problem is compounded when applications get less developer attention. Most APA entries have three- and even two-digit starcounts, unless users are highly technical. Few major Python applications are distributed with PyPI, so download statistics can't help us either. Even if they did, lower-level libraries have way more fanout. And of course free software projects can't lay down big donations or conference sponsorships, so representation tends to be pretty sparse all around. These applications represent the best of the free and living portion of Python. Not only are they a source of utility and pride, but they need our support, in spirit and in practice. It is my sincere hope that the APA will help to anchor the Python community in its real-world applications. What does this mean, concretely? A keen eye will notice how the list is structured. This isn't just for consistent rendering, but an attempt at an API for the dataset. We must explore our ecosystem with the relzationship between libraries and applications in mind. I know I'm going out on a limb here, and metrics aren't everything, but it would be very interesting to see the Python FOSS ecosystem explored as an analogue of the scientific publishing framework. Can we get some sort of developer h-index by treating libraries as "articles" and applications as "journals"? Adding in some application userbase approximations (via social altmetrics and other means) can give us much deeper insight into real-world impact. Next steps If this essay seems shorter than my usual, that's because it's really an introduction to the list itself. I got caught up in several projects' codebases while doing the research, and you will, too. If we've missed a project, please open an issue or PR. If you're as excited about this as I am, consider helping with some of the open issues. There are still a lot of application features to survey: licenses, Python versions, frameworks, and more. And as always, watch this space (and the repo) for updates as we make more discoveries!

Stack Abuse: Python Logging Basics
2018-12-20 14:25:00
Logging helps you keep track of events happening during the execution of your code, which can then be used in the future for debugging purposes. It provides a better picture of the flow of the application and helps developers trace the source of errors that happens during execution of your code, thereby enhancing the maintainability of the application.

gamingdirectional: What is your top achievements?
2018-12-15 12:33:18
After the previous article, we have finally been able to create a score scene as I had promised you before in the last article. What this scene does is to list out the latest 5 levels that the player has achieved, if the level count has reached it’s maximum value then the earliest level from the list will be removed and get replaced by the latest level at the end of the list.

codingdirectional: Move files from one folder to another folder with python
2018-12-15 05:22:20
After I have finished writing the python program which will remove the duplicate files in another folder, the first part of this tkinter’s project has come to an end and the second part will follow.

Stack Abuse: Introduction to Web Scraping with Python
2018-12-14 16:11:00
Web-scraping is an important technique, frequently employed in a lot of different contexts, especially data science and data mining. Python is largely considered the go-to language for web-scraping, the reason being the batteries-included nature of Python. With Python, you can create a simple scraping script in about 15 minutes and in under 100 lines of code. So regardless of usage, web-scraping is a skill that every Python programmer must have under his belt.

Will Kahn-Greene: Socorro: migrating to Python 3
2018-12-14 15:00:00
Socorro is the crash ingestion pipeline for Mozilla's products like Firefox. When Firefox crashes, the Breakpad crash reporter asks the user if the user would like to send a crash report. If the user answers "yes!", then the Breakpad crash reporter collects data related to the crash, generates a crash report, and submits that crash report as an HTTP POST to Socorro. Socorro saves the crash report, processes it, and provides an interface for aggregating, searching, and looking at crash reports.

Jeff Knupp: How To Do Just About Anything With Python Lists
2018-12-13 08:02:00
Python's list is one of the built-in sequence types (i.e. "it holds a sequence of things") is a wonderfully useful tool. I figured I'd try to determine what people are most often trying to do with lists (by analyzing Google's query data on the topic) and just bang out examples of "How do I do X with a list in Python?"

Yasoob Khalid: Research Writeup: Deanonymization and Proximity Detection Using Wi-Fi

The university just published its annual catalogue of all the research projects which happened over the summer.  My research was done under the mentorship of Aaron Gember-Jacobson. I could not have asked for a better advisor. Here is the writeup of my project:

codingdirectional: Remove duplicate files project is ready
2018-12-12 12:15:04
I am glad to inform you all that the remove duplicate file project written with python has finally completed and now it will be uploaded to github for you all to enjoy. This is a free software and it will always remain free. Although I would really love to create a linux version of this remove duplicate file software but because I do not have a linux os’s computer therefore at the moment this software is just for the windows user only. I have packed this software up where you can just click on it to open it up to search and destroy the duplicate files inside your computer. Here are the steps you need to do to search and destroy the duplicate files:

Welcome back, let us continue with our previous pygame project. In this article we will first create a text file which will be used to store the game level. This text file will be called level.txt which will be stored within the project folder. We need to create this text file by hand and type in 1 which is the first level of the game onto it, this level number will be rewritten each and every...

codingdirectional: Tell the user how many duplicate files have the python program deleted
2018-12-12 03:38:39
Welcome back again, in this chapter we will create a message box to tell the user how many duplicate files have been deleted from each selected file. The game plan here is simple, we will attach a message variable to the label widget and pass that widget to each remove thread instance so the program can modify the content of that message by adding in the selected file name as well as the total number of duplicate files that have been remove from the selected folder. That modify message will then be shown by the messagebox on the main thread at the end of each file deleting process. The first file we need to edit is the main file where we will pass in the tkinter’s label object with the message variable to each new remove thread instance which the program has created, the remove thread instance will then modify the content of that same message which includes the total number of duplicate files that have been deleted together with the file name of the original selected file. We need not worry too much about whether those threads will compete with each other to modify the content of the message or not because one process will finish before another so therefore there is always a time gap in between the process in this case. Here is the new version of the main file.

Jean-Louis Fuchs: Announcing libchirp
2018-12-11 23:00:00
I proudly announce libchirp. I believe queues, message-routers and patterns like pub-sub are the way message-passing should be done. However, I also believe they should be optional and tweak-able. libchirp does only one thing: message-passing with encryption. All other building-blocks should be implemented in upper-layer modules or daemons. libchirp is the basis for modular message-passing and actor-based programming.

gamingdirectional: Create a home button on the pause scene

First we will need to modify the start scene class by adding an extra button into it.

codingdirectional: Don’t delete the same file in it’s own directory
2018-12-11 03:26:48
Welcome back to the next chapter of the delete duplicate application, in the previous chapters we have successfully created a multiple files selector which will delete all the duplicate files in another folder. And in this chapter we will further tune up the program to make sure we can also delete all those duplicate files in the nested folders that are contain in the same folder where the file which we want to search for it’s duplicate version is located. The first file which we need to change is the main file, the program will need to make sure the user has selected a file to search for it’s duplicate version as well as the user has selected a folder to search for the duplicate file or else a message box will pop up to warn the user about that. The program will also pass in the folder path which the selected file is located to the remove thread so the thread will not search and delete that selected file.

Podcast.__init__: Gnocchi: A Scalable Time Series Database For Your Metrics with Julien Danjou
2018-12-10 05:04:04
Do you know what your servers are doing? If you have a metrics system in place then the answer should be “yes”. One critical aspect of that platform is the timeseries database that allows you to store, aggregate, analyze, and query the various signals generated by your software and hardware. As the size and complexity of your systems scale, so does the volume of data that you need to manage which can put a strain on your metrics stack. Julien Danjou built Gnocchi during his time on the OpenStack project to provide a time oriented data store that would scale horizontally and still provide fast queries. In this episode he explains how the project got started, how it works, how it compares to the other options on the market, and how you can start using it today to get better visibility into your operations.

Polyglot.Ninja(): Auto incrementing IDs for MongoDB
2018-12-06 17:14:35
If you’re familiar with relational databases like MySQL or PostgreSQL, you’re probably also familiar with auto incrementing IDs. You select a primary key for a table and make it auto incrementing. Every row you insert afterwards, each of them gets a new ID, automatically incremented from the last one. We don’t have to keep track of what number comes next or ensure the atomic nature of this operation (what happens if two different client wants to insert a new row at the very same time? do they both get the same id?). This can be very useful where sequential, numeric IDs are essential. For example, let’s say we’re building a url shortener. We can base62 encode the ID of the url id to quickly generate a short slug for that long url.

Stack Abuse: Sets in Python
2018-12-05 16:02:05

Eli Bendersky: Type erasure and reification
2018-12-04 21:39:54
In this post I'd like to discuss the concepts of type erasure and reification in programming languages. I don't intend to dive very deeply into the specific rules of any particular language; rather, the post is going to present several simple examples in multiple languages, hoping to provide enough intuition and background for a more serious study, if necessary. As you'll see, the actual concepts are very simple and familiar. Deeper details of specific languages pertain more to the idiosyncrasies of those languages' semantics and implementations.

Kushal Das: Using hexchat on Flatpak on Qubes OS AppVM
2018-12-04 15:59:00
Flatpak is a system for building, distributing, and running sandboxed desktop applications on Linux. It uses BubbleWrap in the low level to do the actual sandboxing. In simple terms, you can think Flatpak as a as a very simple and easy way to use desktop applications in containers (sandboxing). Yes, containers, and, yes, it is for desktop applications in Linux. I was looking forward to use hexchat-otr in Fedora, but, it is not packaged in Fedora. That is what made me setup an AppVM for the same using flatpak.

Shipping a web application usually involves having your code up and running on single or multiple servers. In this model, you end up setting up processes for monitoring, provisioning, and scaling your servers up or down. Although this seems to work well, having all the logistics around a web application handled in an automated manner reduces a lot of manual overhead. Enter Serverless.

Podcast.__init__: Using Calibre To Keep Your Digital Library In Order with Kovid Goyal
2018-11-26 02:21:38
Digital books are convenient and useful ways to have easy access to large volumes of information. Unfortunately, keeping track of them all can be difficult as you gain more books from different sources. Keeping your reading device synchronized with the material that you want to read is also challenging. In this episode Kovid Goyal explains how he created the Calibre digital library manager to solve these problems for himself, how it grew to be the most popular application for organizing ebooks, and how it works under the covers. Calibre is an incredibly useful piece of software with a lot of hidden complexity and a great story behind it.

2018-11-20 06:22:00
Yesterday night, on #pypa IRC channel, asked about uploading detached gpg signatures for the packages. According to , twine did not upload the signature, even with passing -s as an argument. I tried to do the same in test.pypi.org, and at first, I felt the same, as the package page was not showing anything. As I started reading the source of twine to figure out what is going on, I found that it uploads the signature as part of the metadata of package. The JSON API actually showed that the release is signed. Later, and explained that we just have to add .asc at the end of the url of the package to download the detached signature.

Time series analysis refers to the analysis of change in the trend of the data over a period of time. Time series analysis has a variety of applications. One such application is the prediction of the future value of an item based on its past values. Future stock price prediction is probably the best example of such an application. In this article, we will see how we can perform time series analysis with the help of a recurrent neural network. We will be predicting the future stock prices of the Apple Company (AAPL), based on its stock prices of the past 5 years.

In this tutorial we will learn how to use Pandas sample to randomly select rows and columns from a Pandas dataframe. There are some reasons for randomly sample our data; for instance, we may have a very large dataset and want to build our models on a smaller sample of the data. Other examples are when carrying out bootstrapping or cross-validation. Here we will learn how to; select rows at random, set a random seed, sample by group, using weights, and conditions, among other useful things.

2018-10-30 13:47:00
Machine learning and deep learning algorithms learn from data, which consists of different types of features.

Ned Batchelder: Why warnings is mysterious
2018-10-27 16:04:51
I recently went through a process I’ve done many times before: I tried to configure the Python warnings module, and was mystified. I set the PYTHONWARNINGS environment variable, and it doesn’t do what it seems like it should. I read the docs again, I think I understand what they are telling me, but the code isn’t doing what it seems like it should be doing. Frustrating.

Not Invented Here: Introducing nti.fakestatsd
2018-10-26 14:38:34
Lately at NextThought we've been much more focused on using application level metrics to proactively monitor and understand the run-time characteristics of our applications. Much of the open source stack we are built on top of is already instrumented with the great perfmetrics library. Because of this, when it was time to expand the metrics we collected, perfmetrics was the obvious choice. However we quickly ran into a problem. How should we test the metrics we generated were actually emitted as the StatsD metrics we expected?

Stories in My Pocket: Pathlib: my new favorite module
2018-10-24 16:46:32
Though `pathlib` was introduced in python 3.4 to some praise, I didn't "get" it. Like many things in python, I needed some time to come around and tinker with it before I realized the power within. I can't remember when `pathlib` started "clicking" for me, but I'm sure it was an accidental rediscovering of it via the Dash documentation application. [dsh]{More on Dash in an upcoming post}
