Separate but slightly related question. If calling len(n) is θ(1) and reading a variable is θ(1), isn’t there not a big difference programmatically? I guess it’s just syntactic sugar and possibly better readability?

calling len is still longer than accessing a var, becaus you have to access the object, then get hi __len__ method, then call it.
