I'm new to Python. I think I'd have done it in a similar way (in any
language). Your use of openers/closers looks nice though. In the
initialization of openers, I guess you implicitly create a kind of
hash, right? Then the 'in' operator checks for the keys. That is elegant
because you have the openers and closers right next to each other, not
in separate lists.

But why do you enumerate with start=1? Shouldn't you start with index 0?
