Somehow I made that work at the first attempt without checking anything before. Still can't believe it.
To be fair: I forgot typecasting once in the 19 lines before that.
Has anyone suggestions for improvement?

linking a gist or uploading a bigger picture would be an improvement.

I can't see that LONG python, but if it's your first attempt and it's working, then it's great. Good luck for your future.

If I uploaded more code, people would probably suggest even different approaches instead of implementations only. That is explicitly not what I am allowed nor want to have here.
It would be nice if someone told me how to shorten the lines though.
I know you can hardly read that due to the image compression.

put semicolon for each code block?

heilige scheisse. Diese if anweisung.

egal, schön mal wieder von dir zu hören.
