Nested list looping and wanting to make each loop have index 0 and 1

List

list_a = [[1, 2],[3, 4], [5, 6]]

for index, item in enumerate(list_a):
# do something

Description of task required

My question is, how would I write this loop if I wanted to retrieve each seperate list within list_a as index 0 and 1. At the moment [1, 2] is index 0, [3, 4] is index 1 etc. But what I am chasing is the following:

[1, 2] would have 1 as index 0 and 2 as index 1, then I would perform some task and then move onto the following where [3, 4] would have 3 as index 0 and 4 as index 1 and perform the same task as before. Any help would be awesome! :)

Solution 
  • for small_list in list_a:
    for index, item in enumerate(small_list):
        print index, item
