Question

I want to be able to interate both list1 = list('asdf') and list2 = list('qwer') at the same time. What is the best approach?

for i, p in list1, list2:
    print(i,p)

Where i would be increment list1 and p would be increment list2.

Answer 1

Use zip (or itertools.izip if the two lists are large):

for i, p in zip(list1, list2):
    print(i, p)

Alternately, if list1 might not be the same length as list2 use izip_longest from itertools
