HTML IDs removed in various versions of CPython docs.

3.10 is skipped; couldn't get it to build quickly. These are not YAML; extensions are just to get syntax highlighting on GitHub.

A printer-friendly style for the PyCon US 24 schedule pages, taken from Hugo's blog post.

Paste the following into the browser console. (You might get a warning about not pasting code you don't understand -- it's there for the same reasons why I don't like installing browser extensions that someone recommends to me.)

The style will only change when you print (or do a print preview).

var sheet = document.createElement("style");
sheet.innerHTML = `

A function may be shadowed by a static inline function or macro with the same behavior. Typically, this allows better performance for C/C++.

Shadowing example

To provide a static inline equivalent to an exported function, write something like:

import unicodedata

def get_components(char):
    name = unicodedata.name(char).removeprefix('BOX DRAWINGS ')
    result = []
    for part in name.split(' AND '):
        part = part.replace(' DASH', '-DASH')
        directions = []
        for word in part.split():
            match word:

Python Vendor Configuration

Currently, several Python distributors modify the Python install layout. Making such modifications requires them to patch multiple standard library modules. The install layout is currently not meant to be a configurable option in a Python installation, but Python developers, distro packagers and module authors all have conflicting certain assumptions in this area. This has presented itself as problematic because Python distributors, understandably, fail to correctly modify all places required to satisfy all these assumptions, resulting in incoherent or straight-out broken Python distributions
