having trouble with zippy task.

can you please help me with this code, i feel im close, but missing something

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(count, second_t):
    for index, letter in enumerate(second_t):
        print ('{}, {}'.format(index, letter))
    return second_t

The challenge didn't ask for printing out anything, the challenge is expecting you to return a list.

Also, the first element in the first element of the whole list isn't supposed ot be the index.

You are supposed to use the zip() function, not the enumerate() function.

# 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):
    combo_list = []
    for item1, item2 in zip(iter1, iter2):
        # Over here I'm adding a tuple to the list.
        combo_list.append((iter1, iter2))
    return combo_list

Good luck! ~Alex

I wouldn't say that you're supposed to use the zip function here. That's more of a shortcut that does all the work for you.

You're not fully utilizing what the zip function does.

If you're going to use the zip function then you only need to convert the result to a list.

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

I think the intent of the challenge though was to implement your own zip function.
