My presentation about using rust from python from PyConUS got published very quickly this year 😁 youtu.be/CqOZdTFb4io?...

🚀 tox 4.26 is out! - Introduces free-threaded builds (just add t to your env name) - Adds support for Python 3.14 - Fixes virtualenv no longer bundling wheel on >3.9 - Drops support for Python 3.8 Huge thanks to all contributors! 🙌 🔗 github.com/tox-dev/tox/...

@hugovk.dev now that template strings are a thing can we use them in standard logging to use F string like formatting without performance complications? docs.astral.sh/ruff/rules/l... 🤔

See you there 😎

Thanks for the kind words @willingc.bsky.social 🙏 gaborbernat.github.io/new-wave-of-...

Today on our Speaker 📣 Spotlight 💡 we're highlighting @gjbernat.bsky.social who will be presenting Python Meet The Crab - Friendship At First Sight? Join us April 13 either in-person or virtually to watch. Get your ticket today pytexas.org/2025

What popular Python packages are using Rust (PyO3), I got cryptography, pydantic, ruff, uv and polars. What else am I missing?

PEP 751 has been accepted! peps.python.org/pep-0751/ This means #Python now has a lock file standard that can act as an export target for tools that can create some sort of lock file. And for some tools the format can act as their primary lock file format as well instead of some proprietary format.

@sethmlarson.dev do you have a newer page of Rust vs Python on PyPI chart? Is there a top n (10) most popular packages using rust?

Today on our Speaker 📣 Spotlight 💡 we're highlighting our second tutorial presenter, @gjbernat.bsky.social, who will presenting: The new wave of Python Packaging Join us April 11 in-person for this tutorial and learn all about modern Python packaging! pytexas.org/2025

Seems neither my tutorial or two talk proposals made the cut for this years PyCon US conference :)

Because prettier is a bit heavy weight for formatting XML/XSDs and there's no better alternative for a pre-commit hook that handles XML created xml-fmt pypi.org/project/xml-... (uses under the hood CPython stdlib XML formatter docs.python.org/3/library/xm...) - 3.9+.

Surprised me a bit that pre-commit-uv got 3 million downloads per month after just one of being released. 😱 Way more popular than expected 🤔 cc @crmarsh.com

The latest virtualenv github.com/pypa/virtual... adds support for freethreaded Pythons, thanks Robsdedude for the contribution!

Textual 1.0 has been released. 🥳 Three years in the making. A TUI framework that is bigger than the terminal. To celebrate, I want to give away some trade secrets. Because I am appalling at keeping secrets. Tell me what you think of the diagrams... textual.textualize.io/blog/2024/12...

We're excited to announce the #PyTexas 2025 tutorials! Join us April 11, 2025 as @alsweigart.bsky.social and @gjbernat.bsky.social lead us in two AMAZING tutorials! Get your tickets today: Schedule: https://www.pytexas.org/2025/schedule/tutorials/ Get Tickets 🎫 :

Today is my first day at Astral! Very excited to work with @crmarsh.com and the gang on Python tooling. It'll be fun (and strange) to focus on only one language for a bit!

Wonderful article on python packaging and project management. It focuses on uv. https://reinforcedknowledge.com/a-comprehensive-guide-to-python-project-management-and-packaging-concepts-illustrated-with-uv-part-i/ #python #uv

This cute armadillo wants you to submit to the #PyTexas CFP. He told me so. https://pretalx.com/pytexas-2025/ Deadline to submit: 12/1 @ 11:59pm CST

Proposals for @pytexas.org and @pycon.us 2025 done 😀 Make sure to submit yours before the deadline ends 😇

I wrote a blog post explaining what the #PSF Conduct WG does since I have heard some people get it wrong. snarky.ca/what-the-psf...

@crmarsh.com seen UV@Jane street, you said with rust you have a high confidence that you will be able to run it. I don't share that opinion as I run into in the past cases where some dependency crate failed to compile, especially if you're using more novel platforms like ARM on Windows and MacOS 😅

Cut two releases to virtualenv today github.com/pypa/virtual... 👍

Everyone who just joined and is looking for Python people to connect with, I made a "starter pack" with many of the fun accounts. Add them to your followers list, #python: go.bsky.app/3Uzma1g

I conducted an analysis of return-in-finally in real world Python code. Just don't do it. TL;DR: - it is not used often - when it is used, it's usually used incorrectly - code authors find it easy to fix Draft PEP: peps.python.org/pep-0765/ Full report: github.com/iritkatriel/...

Exploring VS Code compatibility with different @pytest.org plugins this week- got a plugin which is failing? Add a comment 👇 github.com/microsoft/vs... also thanks @brianokken.bsky.social for this top plugin list I'm using as a jumping point pythontest.com/top-pytest-p...

Should we have a short form for variable type casting? How do people handle this Python typing use case? discuss.python.org/t/add-a-shor...

As @hynek.me already noticed, two of the rules this release stabilises are `sort-dunder-all` and `sort-dunder-slots`! These have a special place in my heart, as they were two of my first big Ruff contributions, before I formally joined Astral as an employee bsky.app/profile/hyne...

I just released Ruff 0.8! Lots of exciting features in this release, but there are also a few breaking changes, so I'd encourage users to check out the blog post. The biggest change is that the target-version setting now defaults to Python 3.9 (but this is configurable!) astral.sh/blog/ruff-v0...

If you are a Julia user you should be aware of this: yuri.is/not-julia/

For my open source walkthrough at SF Python, I live coded a fix for an open flask-admin issue, showing how to clone, venv, do an editable install, replicate the bug, fix the bug, add tests, add docstrings, generate the docs, and make a branch. Good way to see pip, pytest, tox, and sphinx in action!

It's me!! I had a chance to catch up with my pals @pablogsal.com and @lukasz.langa.pl on their awesome podcast last week, coincidentally right after my core dev promotion went through. If you like Python, open source, and balloons (!!!), this is the episode for you.

Also, 🚨 new argparse feature alert 🚨 Starting in 3.14, you can optionally enable suggestions for argument choices and subparser names if the user mistypes them via `suggest_on_error`!

Meet our newest member of the core developer team, @savannah.dev! Currently at Snowflake, she worked with dev tools at Docker and Microsoft, but also flew drones over forests. In terms of CPython, Savannah works on argparse and the JIT, but that's not her last word. open.spotify.com/show/1PGRfdr...

tox+uv is turning out to be a great pair of tools for quickly addressing maintenance debt. It's trivial to build a test environment that actually tests against your claimed minimum versions, and it builds fast. uv_resolution = min: lowest-direct github.com/tox-dev/tox-uv #python
