Here is another way to write your function n_wise. [python] from itertools import islice, izip, tee def n_wise(iterable, n): n_iterators = tee(iterable, n) zippables = (islice(it, j, None) for j, it in enumerate(n_iterators)) return izip(*zippables) [/python] The itertools module is one of my favorites. Here is another way to write your function n_wise.

from itertools import islice, izip, tee

def n_wise(iterable, n):
    n_iterators = tee(iterable, n)
    zippables = (islice(it, j, None) for j, it in enumerate(n_iterators))
    return izip(*zippables)
