You would think so, but Python has a built-in exception to signal that an iterator has nothing else to yield: https://docs.python.org/3/library/exceptions.html#StopIte...
Seems to me that the fact that an iterator has been fully drained is not exactly an unexpected event. That's bound to happen at some point. And yet, exception. (Because sure, how else are you going to signal this?) Using exceptions for multi-level loop exit seems rather similar to this use case.
