style: Prepare introduction of ruff and ruff format

[echoix]

I'm preparing the repo to use ruff and ruff format, like the main repo.

Most of the changes here are to apply non-conflicting changes, in other words, ruff format changes that are not reverted by the current black style. It will make reviewing the next PRs easier.

Cool! Didn't realized we switched from Black.

I checked just couple files at random while scrolling through it, but it looks good.

There were all correct, except 2 or 3 places. 1 had a implicit string concatenation merged together and it had an extra space between sentences that I removed, and 1 or 2 had a comma after the print, making a tuple, similar to what we fixed in the main repo yesterday/today.

It was discussed since a month, but it was implemented this weekend and merged this afternoon. So you're not late on the news haha
