Enumerate two python lists simultaneously?

Question

How do I enumerate two lists of equal length simultaneously? I am sure there must be a more pythonic way to do the following:

for index, value1 in enumerate(         


        

Answer 1

from itertools import count

for index, value1, value2 in zip(count(), data1, data2):
    print(index, value1, value2)
