For Win XP SP3 I do next in py30.b1:

a=[9,8,1,2]
it=iter(a)
it.next()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'list_iterator' object has no attribute 'next'

but doing:
it.__next__()
9
it.__next__()
8

it is ok.

However, manual of Py3.0 indicates iter.next() as valid.

Python 25 does not accept "it.__next__()" but "it.next()"
Regards.

Where in the 3.0 docs do you see it.next() used? It should be changed.

Please, go to python 3.0 -> python manuals and search with word: iter
then select first line of found titles, i.e. Functional Programming
HOWTO. Into this title you will find some samples.
