not sure what's wrong here.

combo([1, 2, 3], 'abc')

Output:

[(1, 'a'), (2, 'b'), (3, 'c')]

def combo(iter1,iter2): return zip(iter1,iter2)

combo('abc','def') [('a', 'd'), ('b', 'e'), ('c', 'f')]

Looks correct to me

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

def combo(iter1,iter2):
    return zip(iter1,iter2)

A "zip object" is not quite the same thing as a list, but you can convert it into one to get the correct output:

    return list(zip(iter1,iter2))

But the challenge specifically wants you to implement the process yourself so it won't be quite that easy. :smirk:
