Need help with combo!

Can someone please tell me why this isn't working? thank you!!

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

def combo(iterable1,iterable2):
    list_of_tuples=[]
    for item in iterable1:
        for item1 in iterable2:
            tuple1=item,item1
            list_of_tuples.append(tuple1)
    return list_of_tuples

First off, you should only need one for loop to iterate over both iterables.

for item in iterable1:
    # do something with iterable1 and iterable2

This will work because both iterables are the same length, so the loop will run as many times as there are items in either iterable.

When looping over the two iterables, you need a way to keep track of what index you're at on each loop. One solution would be to set up a counter variable before the loop. Then you can use that variable as the index number for iterable1 and iterable2, incrementing the counter by one at the end of each time through the loop.

Let me know if you need further clarification!
