If you want the indexes also, you can do this:

for i, x in enumerate(steve):
    print(i, x)

If you really want just the indexes and not the values, then you can do this:

for i in range(len(steve)):
    print(i)

Most of the time though you will not need the indexes, and it will be
simpler just to work with the values by looping directly over the
list.
