Can someone please help me understand what is wrong with my code

Hi,

I have tried to answer the following question

*Create a function named combo that takes two ordered iterables. These could be tuples, lists, strings, whatever. Your function should return a list of tuples. Each tuple should hold the first item in each iterable, then the second set, then the third, and so on. Assume the iterables will be the same length. *

with this code,

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

def combo(first, second):
    dict = {}
    for i, value in enumerate(first):
        dict[value] = second[i]
    return dict.items()

and it doesn't pass. Can anyone please help me to fix it?

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

def combo(first, second):
    dict = {}
    for i, value in enumerate(first):
        dict[value] = second[i]
    return dict.items()

Your approach is close to correct! The method items() returns a iterator not a list. To get the desired list, wrap your returned object with the list() function.

Post back if you need more help. Good luck!!!
