Why does code not work in challenge?

My code works in workspaces, but does not pass the challenge criteria for some reason, even though I get the exact output the challenge is looking for.

combo.py 
# combo([1, 2, 3], 'abc')
# Output:
# [(1, 'a'), (2, 'b'), (3, 'c')]

def combo(iterable1,iterable2):
    my_list = []
    index = 0
    for iterable in iterable1:
        new_list = [iterable1[index],iterable2[index]]
        my_list.append(new_list)
        index += 1
    return my_list

Maybe you're not getting the exact output the challenge asked for. The instructions say "Your function should return a list of tuples." And that's underlined in the challenge like that (but I would have added it otherwise).

Anyway, you're creating little lists instead of tuples and adding them to the big list. Lists are identified by brackets "[]" and tuples by parentheses "()". Optionally, you could rename "new_list" to "new_tuple" but it will work just as well with any name as long as it contains a tuple.
