Python: Linting

[theCapypara]

Currently Python code is not checked against any linting rules. We should check the merged demos and determine some linter configurations that we think would make sense to enforce.

As a linter we should probably use ruff, in that case we may also evaluate if it makes sense to replace black with it.

I'm for ruff. In my experience, it's very strict by default, but can be customized pretty easily using config files.
