Python Weekly

Welcome to issue 576 of Python Weekly. Let's get straight to the links this week.

From Our Sponsor

Retool Workflows is a fast way to build and automate recurring cron jobs, custom alerts and ETL jobs. Stop provisioning infrastructure and maintaining one-off scripts. Start automating jobs 10x faster with Retool Workflows. Code level control when you need it, GUI when you don’t.

What’s New In Python 3.12
This article explains the new features in Python 3.12, compared to 3.11.

How to Benchmark (Python) Code
There are plenty of ways to measure the speed of your code. Let me show you a few that I considered for the Writing Faster Python series.

unittest’s new context methods in Python 3.11 (with backports)
Python 3.11 only made one change to unittest, but it’s a good one: context manager methods. These methods can simplify setup and teardown logic in many cases, such as dynamic use of unittest.mock. In this post we’ll look at a couple fo examples using the new methods, and a backport you can copy-paste into your projects, in plain and Django flavours.

ABI compatibility in Python: How hard could it be?
This post will cover just one tiny piece of Python packaging’s complexity: the CPython stable ABI. We’ll see what the stable ABI is, why it exists, how it’s integrated into Python packaging, and how each piece goes terribly wrong to make accidental ABI violations easy.

Who controls parallelism? A disagreement that leads to slower code
If you’re using NumPy, Polars, Zarr, or many other libraries, setting a single environment variable or calling a single API function might make your code run 20%-80% faster. Or, more accurately, it may be that your code is running that much more slowly than it ought to. The problem? A conflict over who controls parallelism: your application, or the libraries it uses. Let’s see an example, and how you can solve it.
