I’m not sure I understand how the `border` variable works.
Sets in Python are really cool when you can master them, but I do sometimes wonder if they are too clever, or just not evangelized enough.

so this:
border = north | south | west | east
border = north.union(south, west, east)
border = set()
for border_set in [north, south, west, east]:
for state in border_set:
border.add(state)
to do it with lists you would need to make sure there was no doubles yourself. plus you wouldn't get the set operations later on, and would need similar loops to check things.
border = []
for state in north + south + west + east:
if state not in border:
border.append(state)
edits throughout as I thought of other things.
I usually avoid using bitwise operators because they get confusing, and the kind of stuff my team does rarely needs them. In this case I would have used union.
edit: here are some of the docs
Bitwise operators: https://wiki.python.org/moin/BitwiseOperators
and how they work with sets: https://docs.python.org/3.10/tutorial/datastructures.html#se...
Plus the set docs have the methods with their corresponding operator: https://docs.python.org/3.10/library/stdtypes.html#set
I can see how it would be nice and concise, but I think the methods are easier to understand.
So python is implementing an existing paradigm, not trying to be clever inventing something new. I'm happy with that
