令和が生んだPythonistaとして華々しいデビュー戦です！. ようわからん罠が多すぎ！.PyPyとかCPythonとかようわからんから、そっちでやってくれ！.再帰の時に深さを拡張する必要があるとかも、そっちでやってくれ！.なんでもええからよしなにやってくれ！. #AtCoder #ABC417

Yesterday I learned that there's a file in the CPython codebase called that makes reference to a fabled "BurntSushi format".

3月にcpythonにuuid7が入った。.

PSA if you haven't used python in the past 5 years it's a completely new language now. - uv solved the package management problems entirely.- mypy type checks have become actually useful.- cpython is now much faster.- polars + fastapi + ruff replaced pandas + flask + black.

We just fixed what was probably the most-reported issue ever with our CPython builds. If you've run into problems with Tcl/Tk (tkinter) or matplotlib when using a uv-installed Python, upgrade now:.```.uv self update && uv python upgrade --reinstall.```

Can you execute arbitrary Python code from only a comment? This was the premise of a recent CTF challenge, which I solved after diving into the CPython source code with the help of @HacktronAI (after a long night chasing a dead end, customising a few Hacktron agents helped me to

2年連続でPyCon JP登壇してきます！今のところ採択率100%で嬉しいです。.昨年はCPythonの整数型や浮動小数点型の内部実装について。.今年はCPythonのスレッド実装について発表します。.広島でお会いしましょうー！.#pyconjp2025 #PyConJP

ローカルにPyPy実行環境用意したらCPythonの100倍以上速くてビビった。こんなに違うものですか？

I've been working on CPython's JIT compiler from the very start. Here are some reflections I have on it. Some points are hard to swallow, but I have to point them out if we are to grow.

just learnt Microsoft fired faster cpython team and cancelled support for it. this is after i learnt they fired ZaZ earlier (physics of LM) and WizardLM team. wtf microsoft? @satyanadella this is unfknbelievable.

5月末のマイクロソフトの解雇はかなりソフトウェアエンジニアとしては考えさせられるもの。下っ端エンジニアとかではなく本社のコアエンジニアも解雇されてる。10年以上勤めてきたCPythonやTypeScriptのコア開発者も解雇してて、今後「プログラマ」として生きていくのは相当厳しいものになると感じる.

some recent changes to my workbench -. - cpython the snake plant.- halon release warning sign I found on the ground in a parking lot.- gridfinity, aka turning long plastic into square plastic.- prototype 3 of my science fair ahh tinfoil crossflow heat exchanger

- Git is in C.- Vim is in C.- Linux is in C.- macOS is in C.- MySQL is in C.- CPython is in C.- Windows is in C.- Photoshop/GIMP in C. You still want any other reason to learn c ?.

soooo TIL pypy exist .It’s 3x times faster than CPython?. where is the catch?

I have seen things in the depths of cpython that you cannot comprehend. Imagine coming across this without knowing the terminology.

「Metaが社内で使ってる高速なPython実装がある」と聞けば、それだけで興味を惹かれるだろう。その名はCinder。CPythonをベースに、JITや静的型による最適化を加えて、パフォーマンスを大きく引き上げた独自の派生系だ。. SNSでは「JITで関数単位の最適化ができる」「Type.

>Linux is C.>Git is C.>Python interpreter(CPython)is C.>Ruby interpreter(MRI)is C.>PostgreSQL is C.>SQLite is C.>Redis is C.>MySQL is C++.>Unreal Engine is C++.>Chrome is C++.>Windows kernel is C.>macOS kernel (XNU) is C.>Photoshop is C++. still, you are not convinced to learn.

PEP-734: субинтерпретаторы в Python 3.14. Никита Соболев, core-разработчик языка CPython и автор серии видео о его устройстве, продолжает свой цикл статей про детали реализации Python. Новый материал посвящён субинтерпретаторам:

Very few people know this, but the official python runtime is called "CPython" because it's half C and half Python.
