Why isn't this code working: combo.py

I can't quite figure out why this code won't work. When having numbers as arguments the code works completely fine, but when having strings as arguments it causes an error. Why?

def combo(string1, string2):
    list3 = [string2]
    list1 = list(enumerate(list3, string1))
    return(list1)

Thanks

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

def combo(string1, string2):
    list3 = [string2]
    list1 = list(enumerate(list3, string1))
    return(list1)

The instructions tell you the function takes ordered iterables as arguments, such as tuples, lists, or strings. It should not operate on numbers, as they are not iterables.

Here's a few hints:

  • you might need a loop
  • you won't need "enumerate"
  • you're not allowed to use "zip"
