If you use GitHub Actions to publish to #PyPI, I wrote a blog post outlining what I consider the key things you can do to secure your publishing workflow. snarky.ca/how-to-publi... If you don't use GitHub Actions for publishing, this post will NOT be of interest to you.

@tiangolo.com are there any plans for hosting SQLite3 databases on @fastapicloud.com ? For a personal blog I just don't need something as fancy as Postgres which requires setting up another service. All I want is a SQLite3 file that I can occasionally download for backup purposes.

Setting up a direct indexing account has generally not been worth the hassle, but it sure feels great to be able to exclude SpaceX from my investment list

The rainbow is here all year long, so we don't need to change the profile for June. But it is a good time to remind everyone that LGBTQIA+ rights are under attack all year long as well. And to steal @haskell.org's message: there would be no Gleam without trans people 🩵🩷🤍

Gleam is free from corporate interference and control, but that means financially we rely entirely on our sponsors! Please consider supporting Gleam, even if just a couple of dollars. Thank you! 💖 gleam.run/sponsor/

Why is @bsky.app showing me a banner for elections in the US?!? I don't live there! I can't vote in their elections! @bsky.app just lost a ton of cred with me.

🐍🚀 Out now: Python 3.15 beta 2! 💤 Lazy imports! 🧊 frozendict builtin! 💂 sentinel builtin! 📉 Tachyon profiler! 🖼️ Frame pointers everywhere! 🎨 More colour! 🚌 & more! Library maintainer? Add 3.15 to your CI and keep those bugs coming! discuss.python.org/t/python-3-1... #Python315 #Python #release

`operator.itemgetter` and `attrgetter` get under-used IMO. Same goes for `else` clauses on `for` and `while` loops.

Your FastAPI is safe 🔒 Today, FastAPI was incorrectly flagged as malicious by automated tooling from a large company, among several other packages. FastAPI was not compromised. It was a false positive. We were not contacted before publication. This should not happen to OSS.

We have a unique keynote this year: Guido van Rossum - the creator of Python - will be the guest on an episode of the core.py podcast, recorded live from the #EuroPython stage by @lukasz.langa.pl and @pablogsal.com Grab your ticket: ep2026.europython.eu/tickets/ #europython #python

prek now supports cooldown in either user or project config: github.com/j178/prek/re... pre-commit closed and locked the feature request as one of many many duplicates, but I can't find any: github.com/pre-commit/p... #PreCommit #prek #cooldown

PEP 831 (aka "frame pointers everywhere!") was accepted! If you are an author of a C extension or native lib built with a custom build system, it is now strongly recommended you add -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer to CFLAGS so profilers & debuggers can step through your lib.

IT'S HAPPENING!!! 💃 People have asked me for an official @fastapi.tiangolo.com Conference for years. Here we go, let's meet in Amsterdam. ☕️

Note the "installing from pylock.toml" part 😁

The argument of "Hammock Driven Development" is simple: most bugs aren't caused by bad code, they're caused by insufficiently understood problems. More thinking, less typing. Seems more relevant today than ever. Watch the talk here: www.youtube.com/watch?v=f84n...

Sometimes when you're naming a flag, nothing seems to stick. You try for weeks, ask everyone you know, but the "right" name doesn't seem to be there. Eventually maybe you just ship a name that's bad enough that you figure people will read the docs to figure out what it does.

Now there's autocompletion and docs in pyproject.toml for FastAPI 🎉 [tool.fastapi] entrypoint = "main:app" Make sure you have a modern editor and TOML plugin, like @vscode.dev with Tombi 🤓

Very clever. Maybe FOSS should do that. "By using libre office, you just saved 150 euros".

It's almost like going the wrong direction but WAY FASTER isn't a good strategy.

Free-threaded Python with @fastapi.tiangolo.com 🧵🚀 (this is not a thread, just a threads emoji)

PEP 832: virtual environment discovery discuss.python.org/t/106998 This PEP also puts me in a tie with @vstinner.bsky.social for being the 4th most prolific PEP (co-)author. 😅

Real talk on PyCon US hotels and conference economics.

Python Tip #102 (of 365): Use pathlib.Path(directory, filename) to join path strings To join path strings together, instead of: joined = Path(directory) / filename Or: joined = Path(directory).joinpath(filename) You can do this: joined = Path(directory, filename) #Python #DailyPythonTip

Nearly 5 years, countless PRs, a program grown from 1 to 5. Thank you, Łukasz Langa, for defining the CPython Developer in Residence role. Best of luck on the next step of your journey and we'll see you around the community!

Niche but since folks have asked: If you've noticed the prometheus runner (Windows) on doesjitgobrrr.com looking worse lately: tail calls were enabled since that's what shipped in 3.15.0a8, so it's an "interpreter got better" situation, not a JIT regression.

🛡️ Trusty Pub now has a home on the web! lmmx.github.io/trusty-pub/ I’ve really not used GitHub Pages in a minute but was ironically a fitting time to throw zizmor and other good practices in the repo as a demo Also has a (non-exhaustive!) reading list under the Resources tab 👓📖

I said digital attestations and `pylock.toml` would have helped with the litellm attack. People asked for more details, so I wrote a blog post explaining why it would have helped. snarky.ca/why-pylock-t...

Guido van Rossum has decided to start a new project: interviewing "key Python developers from the first 25 years". Here is the one he did with @snarky.ca, posted early this month (h/t @pycoders.com's latest newsletter). #Python [1/2] gvanrossum.github.io/interviews/B...

It makes me pretty sad tbh. I see my friends burning out from having to triage all this trash. I see repos that I used to work on where all human comments on PR reviews are LLM generated. I get folks are using AI but can we not converge toward being 12 LLMs in a trenchcoat maintaining a project?

If you’re looking for a nice, modern, featureful #Python package and environment manager, may I suggest PDM? And maybe also toss some funding their way. pdm-project.org

Because dataclasses have to look at type annotations for e.g. `KW_ONLY`, they will cause lazy imports of type hints to reify. One perk to my record idea is that wouldn't be an issue (snarky.ca/my-proof-of-...). /cc @bitecode.dev

The raise of AI coding tools isn't a surprise because they have the potential to eliminate one of the largest software development productivity killers: searching for usage examples.
