returning a list of tuples, while holding the first item

I don't know what is wrong with my code

combo.py 
# combo([1, 2, 3], 'abc')
# Output:
# [(1, 'a'), (2, 'b'), (3, 'c')]
def combo(a,b):
    output = []
    for i in range(len(a)):
        tup = (a[i],b[i])
        output.append(tup)
    return output

Your code looks good to me. :+1:

So I tested it by pasting it directly into the challenge, and it passed!

Try restarting your browser and see if that fixes it.
