Iterating a sequence two items at a time

Hi!
I have a list [1,2,3,4,5,6] which I'd like to iterate as (1,2), (3,4),
(5,6). I can of course roll my own, but I was wondering if there was
already some existing library function that already does this.
def as_pairs(seq):
i = iter(seq)
yield (i.next(), i.next())
Question to this code: Is the order of the "i.next()" calls guaranteed to be
from left to right? Or could I end up with pairs being switched?
Thanks!
Uli
