Hi @maaijke,

A relatively unimportant issue, but just food for thought. Since this codebase has been around for a while (i.e. during the Python 2->3 era) and has had many contributors over the years, there are a mix of codestyles in place.

IMO, this has hurt some of the code readability and consistency. I'd like to recommend the implementation of a standard formatter / style. My recommendation would be enforcing a tool like ruff. On top of that, a pre-commit hook + CI could be added to enforce / fix codestyle for developers/contributers.

Let me know what you think, and I'm happy to help get these sorts of things implemented.
