Thanks a lot for the effort! I think these are some good cleanups 👍 In some cases I personally wouldn't write it the same way, but in most of them I agree 😄 I mean at this point it's mostly personal preference how to write it and how explicit you want to make it. I think most of the code was written as explicit as possible so that everyone can understand it, especially beginners. But if it's still readable and not too complex I'm also rather a fan of writing code as lean as possible 🙂

I think we loose some explicity - and I got some personal discomfort with the walrus operator - but overall I think this improves both code quality and pythonicness. Thank for your contribution!
