Another #Python (or should I say #CPython) micro-optimization: Instead of using "is" / "is not" comparison in a hot loop over a collection of objects, use index integer comparisons if possible "y == other_y" / "x != other_x". Of course this is only possible in a numeric loop. But yeah apparently "is" and "Is not" perform worse.

Running on CPython 3.12rc2 on macOS 14.0 beta.

Pora na kolejną okresową przypominajkę, że #GitHub Actions, podobnie jak inne systemy CI, o których mi wiadomo, oraz dystrybucje Linuksa (w standardowej konfiguracji) instalują Pythona z wyłączonymi asercjami.

Oznacza to, że ta domyślna konfiguracja *absolutnie nie nadaje się* do testowania, czy twój kod nie łamie konwencji API CPythona. Albo musisz zbudować CPythona z `--with-assertions`, albo skompilować swoje rozszerzenie z `-UNDEBUG`, by obejść to (to drugie rozwiązanie nie wychwyci wszystkich błędów).

A jeśli ktoś włoży wysiłek, by zgłosić złamaną asercję i wyraźnie opisze, w jaki sposób odtworzyć problem, to ten ktoś naprawdę będzie wdzięczny, jeśli nie zamkniesz zgłoszenia, bo "na GHA przeszło".

A Steering Council notice about #PEP703 (Making the Global Interpreter Lock Optional in #CPython)

This year is very intensive in terms of migrations for scientific Python maintainers:
- a new #CPython (3.12) in October
- a major version of #Cython (3.0) announced for this summer
- a major version of #Numpy (2.0) scheduled for the end of the year

All of which will require careful testing and probably take some time to propagate through the giant mess that are dependency trees in scientific #Python 😵‍💫

Looking at a #CPython feature request from a few years ago (as one does) for iterating over extended grapheme clusters, and suddenly a wild @manishearth appears 😁

Hey there, #Python310 users. If you're looking for Python 3.10.12 installers for #Windows, look no further.

We've got you covered.

You may download them from our #cpython fork:

https://github.com/coatl-dev/cpython/releases

Our next #Stockholm #Python meetup will be on 7th, from 5:30pm in the #SUNET office. We will sit down and learn how to build #CPython itself. Hoping to get more people excited about contributing to the language itself.

Łukasz Langa, the CPython Developer in Residence, is speaking about "Working Around the GIL with asyncio" at PyCon US 2023 in Salt Lake City 🇺🇲🐍

He's going through two examples of data processing with Python 3.11 and how asyncio with shared memory helps speed things up ⚡

@aegilops For a while #IronPython appeared to be "stuck" in 2.7 just like #Jython, but in December they released version 3.4 and they've ported f-strings from #CPython 3.6.

I cannot imagine what goes into implementing Python in other programming languages, and for that they deserve my admiration. But it is indeed a shame Jython has not moved past 2.7 in almost eight years.

Maybe Inductive Automation will open their platform to other scripting languages, but until then I'm stuck in 2.7 too.

AI as Render Engine?
🤔 The way is long, but I still wonder why pay for something that is already free or even could be not so expensive?

Below is the first personal attempt to achieve at least one of the abovementioned aims. 😉 my goal, as always, is to extend design possibilities to everyone.
