no zip function??

my code totally works in the compiler, and i dont want to rewrite it all ugly when that lovely zip function is just sitting there. I mean i will, but I figured I'd write this question, just cause my solution does produce the desired result.

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(one, two):
  return zip(one,two)

You are very close. The zip function returns a zip object. To evaluate this object, wrap it in list():

>>> one = [1, 2, 3]
>>> two = 'abc'
>>> zip(one, two)
<zip object at 0x7f277bbb8288>
>>> list(zip(one, two))
[(1, 'a'), (2, 'b'), (3, 'c')]

def combo(one, two):
    return list(zip(one,two))

Thanks! they seem to print exactly the same in the compiler, that really threw me off!
