zip doesn't work

why the following doesn't work?

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

zippy.py 
# combo([1, 2, 3], 'abc')
# Output:
# [(1, 'a'), (2, 'b'), (3, 'c')]
# If you use .append(), you'll want to pass it a tuple of new values.
def combo(iter1, iter2):
    return zip(iter1, iter2)

The only thing that you are missing is that you will need to make it into a list. Other than that you are good.

# combo([1, 2, 3], 'abc')
# Output:
# [(1, 'a'), (2, 'b'), (3, 'c')]
# If you use .append(), you'll want to pass it a tuple of new values.

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

Here is another way you could do it. This way doesn't use zip. Instead it just appends to a list.

# combo([1, 2, 3], 'abc')
# Output:
# [(1, 'a'), (2, 'b'), (3, 'c')]
# If you use .append(), you'll want to pass it a tuple of new values.

def combo(iter1, iter2):
    return_list = []
    for item in range(len(iter1)):
        return_list.append((iter1[item], iter2[item]))
    return return_list
