Python Weekly

Welcome to issue 522 of Python Weekly. Let's get straight to the links this week.

News

This year we are conducting the fifth iteration of the official Python Developers Survey. The goal is to capture the current state of the language and the ecosystem around it. By comparing the results with last year's, we can identify and share with everyone the hottest trends in the Python community and the key insights into them.

Articles, Tutorials and Talks

Learn how to build a full fledged API in Python. The API that we're building is for a social media type application where users can create/read/delete/update posts, as well as like other users posts and of course we will set up user registration and authentication. We will be building this API using the FastAPI library. 

What do GPS navigation devices and websites for booking flights have in common? As it turns out, a lot! For one, both technologies employ Dijkstra’s shortest path algorithm. In this article, we’ll give an overview of Dijkstra’s algorithm and provide an easy-to-follow implementation in Python. After we lay out the explanation in plain English, you’ll see that the Python implementation is not that much different.

In this tutorial, we will create an Ethereum token on the Polygon Network from scratch. To create our token we will use Python and Python-like programming languages.

Adding type hints to urllib3 was clearly a huge amount of work, hundreds of engineer hours across several months. What we once thought would be a purely developer-facing change ended up making the codebase more robust than ever. Several non-trivial logic errors were fixed and our team is more confident reviewing and merging PRs. This is a big win for our users and a very worthy investment.

Various efforts to remove the GIL have been made over the years, but none have come anywhere near the point where they would be considered for inclusion into the CPython interpreter. Now, though, Sam Gross has entered the arena with a proof-of-concept implementation that may solve the problem for real.

This post shows basic examples of how to use DeepSpeech for asynchronous and real time transcription.On Notational Programming for Notebook EnvironmentsThis article provides some thoughts on notational programming and demonstrates a key principle — “variables travel,” where typewritten text can be referenced in handwritten code. The goal is to provoke discussion around “traveling” variables as powerful tools for bridging handwritten and typewritten contexts, for a future version of programming practice less constrained by typewritten input.Why you shouldn't invoke setup.py directlyThe setuptools team no longer wants to be in the business of providing a command line interface and is actively working to become just a library for building packages. What you should do instead depends on your use case, but if you want some basic rules of thumb, there is a table in the summary section.Profiling Django AppThe Django application can consume more than expected memory or time.
