#cpython

CPython internals classes, self, and class vs instance attributes. Class attributes live once, on the class itself, shared by every instance via lookup. Instance attributes (self.x = ...) are private per object. #Python #CPython #100DaysOfCode

CPython internals: @contextmanager. You can write a context manager as a generator instead of a class. Code before yield plays __enter__, the with block runs while the generator is paused, and code after yield plays __exit__. #Python #CPython #100DaysOfCode

Thank you to our first block of Day 1 #rustconf speakers! From the warm welcome to #rustconf26 via Bec Rumbul, to Jon Seager's keynote, to some great project updates from #cpython and #rustls, we covered a lot of ground already 🦀 We're headed into a short break now and will be back for breakouts after that! Weds schedule: Virtual info:

CPython internals: @property, @classmethod, @staticmethod. These are decorators built into Python. @property replaces a method with a property object (area = property(area)) #Python #CPython #100DaysOfCode

CPython internals: context managers and the with statement. with calls __enter__ when the block starts and __exit__ when it ends, whether the block finished normally or raised an error. #Python #CPython #100DaysOfCode

Congrats to Pradyun Gedam (@pradyunsg), an engineer w/ our Python Infrastructure team, on being promoted to #CPython core dev! 🎉 He's been active in the #Python 🐍 packaging ecosystem since 2017, and works on pip, @pypi, @ThePyPA, #Sphinx, TOML, and more.

On this week's @StackOverflow #podcast, @benpopper & @KyleMitBTV delve further into the future of #Python 🐍 with #CPython core developer & Python Steering Council member @pyblogsal Listen to part 2 of their conversation:

Write like Python, run like C. That’s the magic of CPython! ✨ #python #cpython

Senior Editor @nkolakowski of @Dicedotcom conducted a Q&A with #Python 🐍 Steering Council member & #CPython core developer @pyblogsal about the future of the #programminglanguage and how our engineers use it here @Bloomberg

CPython internals: writing my own iterator. A for loop calls __iter__ once, then __next__ on every pass, and stops when __next__ raises StopIteration. That’s what GET_ITER and FOR_ITER in dis output were doing. An iterator whose __iter__ returns self is single-use:

list(c) works once, then gives []. A list can be looped repeatedly because its __iter__ returns a fresh iterator each time. #Python #CPython #100DaysOfCode

🐍 Python 3.15.0rc1 is out! Proud to have contributed to CPython with changes included in the 3.15 release. Congratulations to the @ThePSF community! #Python #CPython #OpenSource #Python315
