1 de abr. de 2014 · In some cases, elif is required for correct semantics. This is the case when the conditions are not mutually exclusive: if x == 0: result = 0 elif y == 0: result = None else: result = x / y. In some cases it is efficient because the interpreter doesn't need to check all conditions, which is the case in your example.
