Thanks! You could even now remove the from typing import List, Tuple, Set, Dict stuff, because from Python 3.9 onwards, it understands the standard list, tuple, set, dict in that context. But the typing import will still work, so it's also fine to do that later 🙂

Let's do that later then. I just did an rg -. "[^0-9]3\.8[^0-9]" and cleaned up the places where you left comments.
