A cool recent #Python change is PEP 783 <#pyodide

My bike riding has been poor this year, due to spinal stenosis and then spinal surgery in June... but hopefully the numbers will go up for the rest of the year.
(And who knows? Maybe I'll update some of the Python code that generates these.)
#bikeTooter #python

It's 2026 and :python: #Python's standard library *still* does not have a flatten function? 🤨
(Yes, more-itertools, that's not the point)

The state of #Python ecosystem right now: almost everything is slop. Some projects are complete vibe-coded slop (autobahn, chardet, cryptography). Some projects are disguised slop ("Coding agents shouldn't co-author themselves.")
There is only a handful of human projects left (Flask being one bright example). And they're being killed. They're being killed by the neverending slew of slop pull requests. They're being killed by all their dependencies becoming slop. They're being killed because this whole ecosystem has became such a complete cesspit that you have zero motivation to do anything.
EDIT: and honestly, this is only going to get worse. When you kill the incentive to work on projects, you only get more slop. Maintainers give in, and more projects become slop. Or they give up, and projects get forked unto slop.

What are we using to package up Python application & dependencies into a single distributable file now?
I'm thinking of bundlers like RollupJS.

I’m somewhat embarrassed to finally announce svcs 26.1.0 – my solution to #Python service location and dependency injection.
It’s been a minute, and the changelog is chuck-full, but the main features are autowiring, which looked like a simple add-on that grew to a four-digit monster diff, and of course, TypeForms that allow registering/getting abstract types!

Release 26.1.0 · hynek/svcs
Highlights In the spirit of "we do these things not because they are easy, but because we thought they were going to be easy" this release brings a great new feature: autowiring! It resolves depend...

I wish #mypy would slow down with adding new features to mypyc, and instead focused on fixing the train wreck that mypyc is right now (since 2023 at least). Like, if your code crashes hard with assertions enabled, then it's broken, period. Ignoring proper testing and shoving the issue under the carpet doesn't make it right.

I don't often write #python but when I do I can apparently write python inefficient enough to start the fans spinning on my workstation for half an hour. It looks like Path's match involves a glob compile for every invocation and I have a lot of files (14k) to check against a lot of patterns (2314).

Who thought it was a good idea to put spinners in a shell script?
`pip install` has been running for a few minutes now at 100% CPU and all progress I see is an effing spinner on the last line.
Had to look at process list to see it's not stuck.

So if you're wondering how great #RustLang is, let's talk about #mypy. Mypy introduced its own Rust - #Python package, ast-serialize. This package had a deep crate dependency that was broken on PowerPC. The issue was fixed a month ago but everything is still blocked on a deep chain of dependencies being updated and released.
https://github.com/mypyc/ast_serialize/issues/68
EDIT: yes, I know, it's not Rust, it's Cargo. Because obviously Rust without Cargo makes so much sense for that one project using it.

speaking of slophub, here's environ-config 26.1.0 (my #Python take on loading config from env variables and secrets from safe places) a minor modernization update. thanks so much to every single name in the thanking section and to github who made it possible:

On my way to Cologne for the next workshop on test-driven development with Python.
#TDD #Python #Testing

The conclusion from a big #Python 3.15 #Gentoo porting run today: the most common kind of #NIH Python package is one providing colorful output on the terminal…

Holy cow, remember to clean your #uv cache from time to time, folks 😅
UPDATE: Seems to contain some links, deleting the cache only freed like 9GiB, but still...
#Python

And the next big blocker for #Python 3.15 in #Gentoo is time-machine. Which is obviously broken. There's a patch but it's #slop and complex, and it's sitting for 3 months already with no reply. Because obviously patching CPython internals is so much a better idea than freezegun ever were. All these time-based tests need all the ricing you can get; portability doesn't matter.

I fully understand the saying "if it works, don't touch it"... but **this** is something else entirely
#Python #LegacySystem

I have a #Python favor to ask. Could someone look at Python 3.15 test failures in itsdangerous? It's blocking quite a large part of package dependency graph in #Gentoo, and the failure looks, errr, dangerous.
https://github.com/pallets/itsdangerous/issues/420

#Python Hypothesis package now requires #RustLang. This is a scale of reverse dependencies I can't handle. I guess this means it's the end of WD40 profiles on #Gentoo, and therefore the end of support for Alpha, ARM<v6, HPPA, M68k, i486 and some other random subsets of architectures and profiles. Thanks for all the fish, etc.
https://github.com/HypothesisWorks/hypothesis/issues/4740

Also, zero days (well, minus a lot of days because I've been slacking) since a random #Python package got a new #NIH dependency on another Python package which is actually a "fastest" #RustLang package which cannot be built because the author thinks it a great idea to require a nightly Rust compiler.
…and of course it's full of "unsafe" calls. Because Rust is obviously such a great language for making secure code.

I finally got around to working on my bike mapping project enough to publish the results...

I’m on my way to Berlin to meet some Pythonistas and old friends: #Python #Django #Berlin

In other news, the #Python semver package has now #RustLang speedups. I'm sure they will come in handy in its reverse dependencies, which are (checks notes) net-analyzer/pontos. I'm sure that package needs to efficiently handle millions of semantic versions a second.

Zero days since I've discovered a random #CPython bug that triggers in very specific circumstances and I don't really have time to report it, nor can expect anyone to do it for me.
This time it's a test failure and refcounts being broken while running fastjsonschema's test suite on #Python 3.15 freethreading with pytest's --junit-xml option enabled 😱. And of course removing --junit-xml makes all tests pass.
EDIT: and of course I cannot reproduce outside Portage. Yet inside, it reliably crashes every single time.

Now time for something that's not related to Gentoo at all.

I suppose there's something telling about the fact that a #Python library for file locks has… [checks notes]… 116 releases already.

Me after laboriously backporting #Python 3.15 fixes to #Django 6.0.x in #Gentoo: "oh, nice, the patchset applies cleanly to 5.2.x as well."
And today, I have to laboriously backport another patch to 6.0.x, and it turns out the backport doesn't apply cleanly to 5.2.x, so I have to laboriously backport it there as well.
I honestly *hate* Django Python version support policy. Shifting all the burden downstream.

Today in things that couldn't have aged well:
"Unpin flit-core dependency" 2 years ago without actually updating the metadata to use the newer pyproject.toml format.
#Python #flit

Isn't it great that #Quart removed support for #Python 3.12 while it's only needed for #dnspython and #urllib3 tests, and we definitely can't remove 3.12 in urllib3? Gotta love the maturity of the Python ecosystem.
#Gentoo

Zero days since the #Python feedparser library switched to yet another #SGMLlib fork.
Yes, #Gentoo has only packaged the previous SGMLlib fork because of them.

Oh no, I've missed another anniversary of sphinxcontrib-websupport 2.0.0 being released broken. Well, the author merged a fix to the git repository since, but never made another release. Let's not forget it's an official #Sphinx package and a required dependency of Sphinx itself.
#Python

Zero days since #pip added a random new functionality that depends on pip being entirely standalone and breaks when you unbundle the dependencies. And I'm unable to figure out why a bunch of tests are still failing.
EDIT: I'd appreciate some help with that. My WIP is at #Gentoo #Python

Zero days since I've named my variable `os`, in #Python.

In the meantime, #GitPython, the package that used to be dead (because the author is busily working on their next great thing) is now slopping out 4 "security" releases a week, as their #slop machine is busily fixing unintended variable expansion in every single URL they call. Unfortunately, they probably don't have enough tokens to fix them all at once, so instead all downstreams have to deal with the churn of endless security releases. Or the brain to figure out that maybe they could just disable variable expansion by default and solve them all at once.
It's truly a great time to be a #Python packager.
#NoAI #NoLLM

So I wanted to unbundle #uChardet from #cChardet #Python package.
It didn't build against system uchardet 0.0.8. So I've checked, and it turns out cchardet is using some old patched fork of uchardet. Ugh.
Fortunately, upstream added the "missing" function too, with a different API (that's not really a problem), but they didn't make a release in 4 years. Ugh.
I could at least replace the old patched uchardet with upstream uchardet, right? Except now I'm getting test failures over misdetected encodings. 0.0.8 works fine there. Though the particular test doesn't look very realistic (note all the repetitions):
#Gentoo

#PSA to #Gentoo users: Please don't upgrade to #CPython 3.14.0b4, that release is borked and causes segfaults in random packages. I've just pushed a mask but warning in case you hit the upgrade before it reaches you. We'll investigate when we have more time.
#Python

In case you're wondering, the #Python zeroconf project is now busy asking people to agree to let them relicense the project from the #LGPL chosen by the original author to make corporations happy, and happily #AI #copywashing the code written by people who don't agree. Of course they also happily ignore what "derived works" are, and only care about lines of code.
#copyleft

Oh, right, in case I thought I'm going to have time to do useful things, I just realized I still need to deal with the humongous #Gentoo fallout from #Hypothesis #Python package requiring #RustLang now.

Do we already have a term for people whose ability to reason has seriously deteriorated after they started relying on #AI? If not, I propose slopbrain.
On a totally different topic, am I missing something here or is the maintainer plain wrong? #NoAI #NoLLM #Python

#Python #pip: so, we have a bunch of `--no-*` options. You can also enable them via a configuration file. Some of them need to be assigned `true` to be enabled, while others need to be assigned `false` instead 🤡.
