Looks great but one quibble -- the "dark mode" simply flips the black and white of normal webpage and code blocks ... which is 50-50

can we use a different shade of grey for code blocks in dark mode?

Right, I agree with this. Reducing some contrast by using shades of grey will look more pleasant. I'll get this adjusted, thanks for the tip!

Thank you for this. Even as a senior Python developer I didn't know many of these.

Glad you found it informative.

I've found senior developers to have polarized opinions about the usefulness of the collection, so always good to see a review in favorable direction :)

> in favorable direction

Speaking of directions, how about the bidirectional use of `yield` and `yield from` ?

# Sending data to a generator (coroutine) using yield from - Part 1

This is beautiful! I've been known to hate on stuff like that walrus operator being added, but this I love. So clean, simple and powerful. Thanks for sharing.

I also learned a bunch of weird things about python from this, like the really gritty details of assignments and such. It's surprisingly messy once you leave the beaten good path.

I also learned that there is python code which causes a rather violent "Don't you ever get that near a code base I maintain"-reaction, which I much rather associated with perl.

Edge cases can keep me awake at night. Reminding oneself that there are no simple things in this enterprise of ours is a good reminder.
