Магия Python: Почему a = 256 и b = 256 — это один объект, а с 257 это уже не работает?
Python часто называют языком, где «всё просто работает». Но за этой простотой скрываются агрессивные механизмы оптимизации, о которых разработчики часто узнают только в момент отладки странных багов. Сегодня поговорим о том, как CPython управляет памятью для малых целых чисел (почему диапазон выбран именно от -5 до 256?), как работает паттерн Flyweight на уровне ядра языка и почему две одинаковые строки могут иметь разные id. А также разберем неочевидную разницу работы компилятора в интерактивной оболочке (REPL) и при запуске скриптов.

TL;DR genuinely interested in hearing why use of #Python pip is being deprecated/discouraged.
Had a disastrous #IT day yesterday. Updating my main server led to mysterious cascading failures.
Fortunately, my backup/test server kicked in. It's a bit slower, but functional, allowing me to work on the main and spin up a new instance (I really need to upgrade the OS on Main).
11:30pm I saw that vendor sales reports hadn't been mailed out. I tracked it down to the postmarker #Python package not being installed.
Now what fresh hell is this? All of a sudden I can't install Python packages that haven't been blessed by the Ubuntu package maintainers?
I found the --break-system-packages option (WTH?), and sales reports were delivered by 11:59 (6:59pm Eastern).
But I'd love to know the rationale behind this if anyone knows. Is it "fixing problems that very few people have in a way that breaks many things", just like Snaps?

Support for PEP 723 (inline script metadata) has landed on pip's main branch thanks to some helpful guidance from the maintainers.
https://github.com/pypa/pip/commit/36987b0c31b97ffb9fb7949ded628e9a6b10c016
Here's hoping it'll smooth out some distribution wrinkles for people who have been getting along with just-pip and single-file scripts paired with requirements files 🤞

Guido van Rossum wanted a language that was easier to use than C, more powerful than shell script, and featured automatic memory allocation.

Eigentliche wollte ich nur meine #python Kenntnisse etwas auffrischen. Der Kurs ist wirklich richtig gut, besser als ich vermutet hätte. Geht an vielen Stellen wirklich richtig genial in die Tiefe. https://www.udemy.com/share/102Vn43@G1SV4usBrRCnuNuD4RG51dnur-kxuq8koRFXsJZGDqYyhYIlcHaexEQPhgSxag==/

Tech advice please!
What is a good, mature, up to date WordPress-shaped-thing? I want something open source, that I can host myself, that has a reasonable CMS editing like experience for blogs etc.
I already have hosting, I program in my day job so know my way about a server. Something in the #python world maybe?
Thanks !
