HN discussionPre-python 3.2, the format used for representing `str` objects in memory depended on if you used a "narrow" (UTF-16) or "wide" (UTF-32) build of Python. Fortunately, wide and narrow builds were abandonned in Python 3.2, with a new way of representing strings : current Python will use ASCII if there's no non-ASCII char, UCS-2 –UTF-16 without surrogate pairs — if there is no codepoint higher than U+FFFF, and UTF-32 el…

HN discussion> In 3.1 it was the default encoding of string (the type str I guess). No, what was used was what sys.getdefaultencoding(), which was already UTF-8 in 3.1 (I checked the source code). At that time, the format used for representing `str` objects in memory depended on if you used a "narrow" (UTF-16) or "wide" (UTF-32) build of Python. Fortunately, wide and narrow builds were abandonned in Python 3.2, with a new way of…

HN discussionHi! I'm the author of this article. Thanks for posting it. The GIL is an old topic, but I was surprised to learn recently that it's much more nuanced than I thought. So, here is my little research. This article is a part of my series that dives deep into various aspects of the Python language and the CPython interpreter. The topics include: the VM; the compiler; the implementation of built-in types; the import syste…

HN discussionPython, for example, has arbitrary precision integers. That means that it is theoretically possible to represent any whole number in Python, at least assuming your computer has enough memory to support it. Under the hood, the `int` object can have several different implementations depending on how large the number is. So small numbers will be represented one way, and larger numbers might be implemented as 64-bit int…

HN discussionI highly recommend Victor Skvortsov's exhaustive, 12-part series, "Python Behind the Scenes," a deep dive into the implementation details of just about every Python language feature one could possibly take for granted. There isn't a single one I haven't learned something from, but some of my personal favorites include: * Part 2, How the CPython compiler works: https://tenthousandmeters.com/blog/python-behind-the-sce…

HN discussionHi! I'm the author of this post. I've been writing asynchronous Python code with async/await for quite a while but didn't have a perfect understanding of how it actually works: what await does; what an event loop really is and how it runs coroutines; what coroutines are; why Python has native coroutines as well as generator-based coroutines; how asyncio works; and so forth... In this post I've tried to answer all th…

HN discussionEffective Python by Brett Slatkin is very good, still going through the Second Edition, but I like the practical side of this book. If you want to go really deeper like the inner working of CPython I'd recommend Anthony Shaw's CPython internals.
