what am i doing wrong? the program runs in the workspace but it won´t run in the challenge. "couldn´t find combo"

the program runs in the workspace but it won´t run in the challenge. bummer: Couldn´t find 'combo'

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

def combo (first, second):

    i=0
    for x in first:        
        a= x, second[i]
        i=i+1
        lists.append(a)

    return lists

Odd that you didn't get an error in the workspace. I would have expected it to complain that "lists" wasn't defined before calling "append" on it. But if you initialize "lists", it should pass the challenge.

If not, check for possible mixing tabs and spaces in the indentation. That wouldn't show up here, but could also cause an issue.
