How should Pyright consider typing stubs with try-excepted imports?
Why (Python) type hinting sucks
I don’t agree with the post - type hinting is awesome in my experience - but it’s a cleverly-crafted argument and there’s some interesting debate in the comments.
Style guides for Google-originated open-source projects
Google's style guide for Python code. Obviously not the law, not even always a good suggestion, but worthy of consideration.
Textual 0.11.0 adds a beautiful Markdown widget
Reddit thread where the Textual Markdown widget was announced.
Also includes the rather hilarious comment "I wish there were more full blown app examples out there", back when Textual was pretty damn new and barely out of the initial "CSS branch" release.

Packaging a Python CLI tool for Homebrew
Handy writeup on how to make a Homebrew formula for packaging a Python-based application.
My User Experience Porting Off setup.py
There seems to be a lot of confusion around setup.py and friends; and while I’ve seen pushback against this post (mostly sniffy gatekeeper stuff rather than helpful feedback), it’s a worthwhile read if only because the confusion is real.
pip.wtf: Inline dependencies for small Python scripts
A tool to include dependencies with a Python script, without the packaging faff. Not sure I need it, not even sure I want it, but damn do I love how it's written up and introduced. I feel the annoyance.

Terminal Emulators Battle Royale – Unicode Edition!
It turns out that Unicode support in Terminals is a lot more difficult than it first appears. A quick overview of special support for Unicode characters in Terminals:
- "Wide" or "Fullwidth" characters, particularly for East Asian languages and emojis, are codepoints that occupy two cells in a terminal instead of one.
- "Zero" width combining characters used in languages such as Arabic, Hebrew, or Hindi do not occupy any cells themselves; instead, they modify the previous character.
- "Zero Width Joiner" (ZWJ U+200D) reduces and combines many codepoints into a single emoji. This is similar to combining, but encoded in a completely different way.
- "Variation Selector-16" (VS-16 U+FE0F) is a special character that, for specific "Narrow" emojis consuming one cell, causes them to become "Wide", consuming two cells.

Packing Python Projects
This tutorial walks you through how to package a simple Python project. It will show you how to add the necessary files and structure to create the package, how to build the package, and how to upload it to the Python Package Index (PyPI).

How We Executed A Critical Supply Chain Attack On Pytorch
"Four months ago, Adnan Khan and I exploited a critical CI/CD vulnerability in PyTorch, one of the world’s leading ML platforms. Used by titans like Google, Meta, Boeing, and Lockheed Martin, PyTorch is a major target for hackers and nation-states alike.
Thankfully, we exploited this vulnerability before the bad guys.
Here is how we did it."
Pydvice: An attempt at bringing (defadvice ...) from Elisp to Python
An implementation of Emacs Lisp's defadvice, for Python.
Sadly thr library itself is very old (14 years old at the time of recording this), and only for Python 2. There is, however, a PR in the repo that makes it work with Python 3.
Python Packaging, One Year Later: A Look Back at 2023 in Python Packaging
How to improve Python packaging, or why fourteen tools are at least twelve too many
"Join me on a journey through packaging in Python and elsewhere. We’ll start by describing the classic packaging stack (involving setuptools and friends), the scientific stack (with conda), and some of the modern/alternate tools, such as Pipenv, Poetry, Hatch, or PDM. We’ll also look at some examples of packaging and dependency-related workflows seen elsewhere (Node.js and .NET). We’ll also take a glimpse at a possible future (with a venv-less workflow with PDM), and see if the PyPA agrees with the vision and insights of eight thousand users."

(How to Write a (Lisp) Interpreter (in Python))
This page has two purposes: to describe how to implement computer language interpreters in general, and in particular to build an interpreter for most of the Scheme dialect of Lisp using Python 3 as the implementation language. I call my language and interpreter Lispy (lis.py). Years ago, I showed how to write a semi-practical Scheme interpreter Java and in in Common Lisp). This time around the goal is to demonstrate, as concisely and simply as possible, what Alan Kay called "Maxwell's Equations of Software."
A Retrospective on Requests
As per the title: a retrospective of requests.
Possibly killer quote: "After receiving our first security disclosure, I was told that Requests wasn't a serious project but instead one person's art project and thus we shouldn't fix the vulnerability. This was despite the project being touted as being used by multiple international government agencies, political campaigns, and boasting about it's #1 download spot on PyPI. So when I say it might be artful, I'm trying to take a neutral stance on what is art and what isn't art and whether the internals of Requests are actually beautiful art."
Will's Tweet announcing that I was going to join Textualize
"In a fantasy tech startup, who would you hire?
For me it would be @davepdotorg and @mathsppblog
But it's no fantasy. Dave and Rodrigo will be starting at Textualize. They will be helping me build Textual. The TUI framework for #Python that will eat some of the browser's lunch."
