That's why we have itertools.islice().

I always forget itertools. Perhaps I should engrave it on my monitor as a reminder.

With iterators being such a fundamental part of Python these days, perhaps one day we'll see the functions in the itertools module become iterator methods, as happened with strings. But that's a discussion for another day.
