I'm not much of a python pro, but it appears the correct
way to iterate is next(i) instead of i.next(). i.next() has
been renamed to i.__next__() on python3, but next(i) works on both.
Pasted below is the following test script ran through python
2.6, 2.7, and 3.3:
i = iter("1,2".split(","))
next(i)
i.next()
i.__next__()
next(i)

>>> i = iter("1,2".split(","))
>>> next(i)
'1'
>>> i.next()
'2'
>>> i.__next__()
