Comparing list and returning index

Question

List1 = ['3','1','2']
List2 = ['0','1','0']
List3 = ['string1','string2','string3']

I want to do

 if List1[i] > 3 and List2[i] = 0 # i = iterating through list1/2 at the same time and comparing them
     print(List3[i]) # i = being the index number found when the if statement is met

#expected output = 'string1'

Please clarify what you are trying to accomplish. Your code comments are too ambiguous. — Rory Daulton, Mar 18 '18 at 11:03

I would use python's build in zip function documentation

for item1, item2, item3 in zip(list1, list2, list3):
    if item1 == item2:
        print(item3)

Hope it helps!

Thanks! I was using a method of that already but didn't realise you could use it for 3 items. Thanks for actually responding instead of moaning about formatting and downvoting like what seems prevalent in newbie questions here – user3820095 Mar 18 '18 at 12:59
