I want to call out two huge problems with Python. I'm not the first to point these out, but they've been bothering me for a while.
I've provided them here to save folks from repeating these. They're now officially "known" and there's no point in repeating …

And https://pypi.org/project/py-web-lp/

more ...The question was "Favorite Design Patterns."
This is tricky because -- well -- so many patterns appear and re-appear in software. Picking a few from the vast world of patterns is fraught with difficulties.
Here are some thoughts:
Few things are as distracting as those god-awful side quests.
In this case, I had to search out all of the examples in my new book drafts.
Once upon a time, it was a manual check of code in the book to be sure it made sense.
Ugh. Not …
Reaching back to 2008. Yes. Decade(s) ago. Python 2.5.

This came up on Twitter and Fosstodon.
See https://fosstodon.org/@vpavlyshyn/109908255464181943 and https://fosstodon.org/@slott56/109908527412493172.
