That question comes up so often it should probably be a standard library function. Anyway, here is an iterator, if that's what you want: >>> from itertools import islice >>> a = range(12) >>> xs = iter(lambda x=iter(a): list(islice(x,3)), []) >>> print list(xs) [[0, 1, 2], [3, 4, 5], [6, 7, 8], [9, 10, 11]] Of course, as the saying goes, there's more than one way to do it ;-) -- http://mail.python.org/mailman/listinfo/python-list
