I think that this question doesn't accept my answer, which gives the right output?

def reverse_evens(something4): return something4[-1::-2]

It turns a iterable like [1,2,3,4,5] into [5,3,1], which is what the question is asking, right?

slices.py 
def first_4(something): 
    return something[0:4]

def first_and_last_4(something2): 
    to_return = first_4(something2)
    to_return += something2[-4:]
    return to_return

def odds(something3):
    return something3[1::2]

def reverse_evens(something4): 
    return something4[-1::-2]
