Python Weekly

Welcome to issue 566 of Python Weekly. Last week, our 11 years old Twitter account @PythonWeekly all of a sudden got suspended and I really don't understand why. We never had any issues whatsoever before. I immediately appealed via their standard process and also I followed up again, but haven't heard back yet. If you work at Twitter or know someone who does and can help me get our account reinstated, I will highly appreciate it.

5 Tips To Achieve Low Coupling In Your Python Code

In this video I share 5 tips to help you write code that has low coupling. I'll show you several examples and also share a story of a technique I used several times in the past that has really helped me reduce coupling and solve more complex software design problems.

Someone’s Been Messing With My Subnormals!
After noticing an annoying warning, I went on an absurd yak shave, and discovered that because of a tiny handful of Python packages built with an appealing-sounding but dangerous compiler option, more than 2,500 Python packages—some with more than a million downloads per month—could end up causing any program that uses them to compute incorrect numerical results.

Accelerate Python code 100x by import taichi as ti
There is no universal solution to all optimization problems. That's partially why Python is fascinating. You can always find/create an easy-to-use tool that can precisely solve your problem at hand. In terms of scientific computing, Taichi is an ideal option within Python that can help you achieve performance comparable to C/C++.

Python String Methods to Know
Python's strings have dozens of methods, but some are much more useful than others. Let's discuss the dozen-ish must-know string methods and why the other methods aren't so essential.

25 Nooby Pandas Coding Mistakes You Should Avoid

This video goes over a list of 25 mistakes commonly made my beginners learning pandas in python. Pandas is a great tool, but there are some pitfalls to avoid!

Python List Comprehensions Are More Powerful Than You Might Think
Python's list comprehensions (and generators) are an awesome feature that can greatly simplify your code. Most of the time however, we only use them to write a single for loop, maybe with addition of one if conditional and that's it. If you start poking around a bit though, you will find out that there are many more features of Python's comprehensions that you don't know about, but can learn a lot from.

Lazy imports for Python
Starting a Python application typically results in a flurry of imports as modules from various locations (and the modules they import) get added into the application process. All of that occurs before the application even gets started doing whatever it is the user actually launched it for; that delay can be significant—and annoying. Beyond that, many of those imports may not be necessary at all for the code path being followed, so eagerly doing the import is purely wasted time. A proposal back in May would add a way for applications to choose lazy imports, where the import is deferred until the module is actually used.

Using a Raspberry Pi as a Bluetooth speaker with PipeWire
Do you have an old pair of PC speakers, or an old Hi-Fi, that you would like to convert into a pair of Bluetooth® speakers to play music from your phone? A Raspberry Pi can be easily used as an audio bridge between a Bluetooth® device and an analog speaker system, to make this possible. In this quick guide, I will show you how to set up the software on a Pi, using PipeWire, to achieve this.
