Trying "reverse_evens" in workspaces returns correct results, but here I can't pass the quiz.

Code:

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

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

def first_and_last_4(thing):
    return thing[:4] + thing[len(thing)-4:]

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

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

Hi Kourosh,

You have the right idea but you have the slices in the wrong order.

You have to get the even indexes first and then reverse that slice.
