Python Python Collections (2016, retired 2019) Tuples Combo

create a function called combo that takes two iterables as arguments and returns a list of tuples

Alright, this one can be tricky but I'm sure you can do it. 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. Check the code below for an example.

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

def combo(iterable_a, iterable_b):
    iterable_a = list(iterable_a)
    iterable_b = list(iterable_b)
    tuple_list = []
    a_tuple = ()
    for value_a in iterable_a:
        for value_b in iterable_b:
            tuple_list.append(a_tuple)
    return tuple_list

your tuple is empty. you create your tuple but after you create it, you are never adding anything in it.
