I really like this interview with Guido von Rossum, Python creator and original Benevalent Dictator for Life (BDfL) of Python development. The questions keep pushing AI as something formidable to be looking forward to, and most of the answers are either a) AI is not special in many regards; b) not looking forward towards AI development.

For comparison, this is the #Python implementation. (And yes, it's 23 "lines" in the file, but if you subtract the boilerplate it's indeed exactly 10 lines of code.)

Alt...

Screenshot of 23 lines of Python. Code follows: from collections.abc import Iterable from dataclasses import dataclass from pathlib import Path @dataclass class SourceFile: path: Path def find_source_files(dir: Path) -> Iterable[SourceFile]: for root, dirs, files in dir.walk(): for name in files: yield SourceFile(root / name) def main() -> None: for file in find_source_files(Path("doc")): print(file.path) if __name__ == "__main__": main()

I have to say I like the #typing system of #Python. The great thing about it, is the optional use. I use it where I see a lot of value (to do things wrong otherwise) and ignore it where things are just very obvious (in my eyes ;)).

It is not ideal either, I agree, but somehow it feels quite pythonic.

I made a Python core team starter pack:

Let me know if I've missed anyone!

Nice benchmark comparison of various #Python versions from @miguelgrinberg

Key takeaway: if you want to do a bubble sort, use Pypy or Rust.

Ok no. 3.14 is the fastest CPython. The JIT is still a work in progress. Free-threaded interpreter is quite nice for multithreading, but not regular stuff yet. Pypy is faster than any CPython. By a lot. But if speed's all you care about, maybe Rust.

What are you looking forward to?

Three days until release and a bug in the Linux kernel has turned a dozen buildbots red...

It's already been fixed in the kernel, but will take some time to bubble up. We'll skip that test for relevant kernel versions in the meantime.

Release day!

First off, check blockers and buildbots.

A new release-blocker appeared yesterday (because of course) but it can wait until 3.14.1.

https://github.com/python/cpython/labels/release-blocker

Three deferred-blockers are also waiting until 3.14.1.

https://github.com/python/cpython/labels/deferred-blocker

A new tier-2 buildbot failure appeared yesterday (because of course) but it had previously been offline for a month and will need some reconfiguration. Can ignore.

https://buildbot.python.org/#/release_status

OK, let's make a Python!

#Python #Python314 #release

Next up, merge and backport the final change to What's New in Python 3.14 to declare it latest stable.
https://github.com/python/cpython/pull/139631

Now start run_release.py, the main release automation script, which does a bunch of pre-checks, runs blurb to create a merged changelog, bumps some numbers, and pushes a branch and tag to my fork. It'll go upstream at the end of a successful build.

Then kick off the CI to build source zips, docs and Android binaries.
https://github.com/python/release-tools/actions/runs/18308460797

#Python #Python314 #release

Alt...

A GitHub Actions build matrix showing an initial verify-input followed by parallel build-source (itself followed by test-source), build-docs, and build-android (consisting of aarch64 and x86_64 jobs).

(That's actually the second CI attempt, we had to update some script arguments following an Android test runner update.)

This build takes about half an hour.

I've also informed the Windows and macOS release managers about the tag and they will start up installer builds.

This takes a few hours, so I've got time to finish up the release notes.

PEP 101 is the full process, but much is automated and we don't need to follow it all manually.

https://peps.python.org/pep-0101/

#Python #Python314 #release

The Windows build has been started.

The jobs with profile-guided optimisation (PGO) build once, then collect a profile by running the tests, and then build again using that profile, to see how "real" code executes and optimises for that.

https://dev.azure.com/Python/cpython/_build/results?buildId=164907&view=results

Meanwhile, the docs+source+Android build has finished and the artifacts have been copied to where they need to go with SBOMs created.

#Python #Python314 #release

Alt...

The Windows build on Azure Pipelines. Lots of boxes for each of "build binaries", "sign binaries", "generate layouts", "pack", "test" and finally "publish". So far nearing the end of the build binaries stage.

The Windows build is ready and macOS is underway.

@chrisjrn.fyi Interesting proposal they're making there.

I've been tinkering with the AI-assisted autocompletion in #PyCharm recently - only on open source projects so no concerns about code privacy - and it's been slightly helpful but overall a very mixed bag. It'll be interesting to see if it gets better as they collect more data.

#Python

I’m somewhat exhausted to announce attrs 25.4.0!

The main reason for this release (and why it's published today) is that it ships the first pieces of work for Python 3.14 and PEP 749. There will be more work required and there's going to be a lot more churn once everyone starts testing 3.14 earnestly. We hope to receive more feedback before spending more time on this. #Python

@wildrikku To be fair, the URL handling is a particularly poorly structured portion of the #Python standard library. (Partly because the documentation for `HTTPResponse` lives at a very non-obvious place, https://docs.python.org/3/library/http.client.html#httpresponse-objects)

Most people just use external libraries like `requests` or `httpx`, which are much easier to use than the standard library's `urllib`; I would recommend that.

@wildrikku @mark Wait there's *another* requests library? 😵‍💫 I'm talking about this one: https://pypi.org/project/requests/

I'd add that I think one of the emerging strengths of Python is how easy it makes it to use dependencies, especially with inline script metadata (https://packaging.python.org/en/latest/specifications/inline-script-metadata/). So the reasons to avoid dependencies are getting less and less relevant, and people who dogmatically insist on avoiding dependencies without a good reason - not saying that's you, but those people are out there - appear increasingly out of touch with modern best practices.

That being said, I still think it'd be a big improvement if the Python stdlib included better-designed URL handling modules, but realistically, I don't think that's going to happen. It's just that, because of the rich third-party library ecosystem, that's not as big of a problem as it would otherwise be.

I don't want to use anything Microsoft or Microsoft-adjacent for authoring Python. I *had* been using PyCharm Community Edition, because that tends to be the preferred IDE at work. However, with JetBrains now making us opt-out of something AI related (I don't even care what the details are), I want to use something else.

Zed looking interesting, but it's AI front and center.

At this rate I'll end up on Thorny or something. But seriously, what simple IDE are people using these days?
