Thanks. In that case I was modifying items and needed them to be updated
during the loop. I kept the solution as is and my tests pass in 2 and 3.
I will consider using six. Currently all my modules begin with:
from __future__ import division
try:
from itertools import izip as zip
except ImportError:
pass
Which might even become longer if I find other bugs ;-)
