zip() function

Why the platform don´t let me use zip() function?. I copied and paste the code in sublime text and get the right answer

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(a, b):
    return zip(a, b)

Hi there. The challenge asks you to return a list. All you have to do is wrap your zip(a, b) in list() and your code should pass the challenge:

def combo(a, b):
    return list(zip(a, b))

Thanks, Haider
