How to do it...

The itertools module is a treasure of valuable functions when working with iterables, and with minor effort it's possible to get the nth item of any iterable:

import itertools

def iter_nth(iterable, nth):
    return next(itertools.islice(iterable, nth, nth+1))

Given a random iterable, we can use it to grab the element we want:

>>> values = (x for x in range(10))
>>> iter_nth(values, 4)
4
