Combo

Hi.

Can anyone tell me please why this won't pass? The error message just says to try again.

Cheers

Sean

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(iterable_1, iterable_2):
    tup_list = list(zip(iterable_1, iterable_2))

Close, but you didn't return anything!

Try returning tup_list like this:

def combo(iterable_1, iterable_2):
    tup_list = list(zip(iterable_1, iterable_2))
    return tup_list

Also, you can just return the value of tup_list directly.

def combo(iterable_1, iterable_2):
    return list(zip(iterable_1, iterable_2))

Good luck! ~alex

Hi Alex.

I admit I forgot to return tup_list. Your first solution paid off.

Thanks again.

Sean :-)
