Fix Python – Loop through list with both content and index [duplicate]

by

Question

Asked By – Oriol Nieto

It is very common for me to loop through a python list to get both the contents and their indexes. What I usually do is the following:

S = [1,30,20,30,2] # My list
for s, i in zip(S, range(len(S))):
    # Do stuff with the content s and the index i

I find this syntax a bit ugly, especially the part inside the zip function. Are there any more elegant/Pythonic ways of doing this?

Now we will see solution for issue: Loop through list with both content and index [duplicate]

Answer

Use the enumerate built-in function: http://docs.python.org/library/functions.html#enumerate
