My last code chalange step doesn't work. Don't know why?

It works in the python chell, but in the code chalange it gives me error massege back.

def first_4(whatever):
    return whatever[:4]

def first_and_last_4(singleitr):
    return (singleitr[:4] + singleitr[-4:])

def odds(nums):
    return nums[1::2]

def reverse_evens(m):
    return m[-1::-2]

Try your function with [1, 2, 3, 4, 5, 6], and you'll see the problem.
