Thanks for your contribution.

I fixed your type hints:

• any is not a type, but a python built-in function you need to use typing.Any-
• your fetch_json might return a list (collections) or a dict (municipalities)

The easiest way to fix this would be to just use Any (or no type hints) there, but I like that my IDE knows what could be in the dict and does some sanity checks for me, so I added these TypedDicts. (maybe run mypy next time to check your types or make sure your IDE does these checks)

and I did some reformatting (black, isort)

You can run all these checks using pre-commit

Thanks @5ila5 for your fixes, appreciated. I work in cybersecurity and am far from an experienced developer :-)
I am always open to learn something new. Also thanks for the merge.
