How can I fix my code

Hello. In challenge 4 of 4 I am supposed to return all even items in reverse, however I am stumped. How can I fix my code.

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

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

def reverse_evens(reverse_list):
    return reverse_list[:1:5]

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

Hi Logan,

You can't solve this with a single slice. So you'll need to do it in two steps: first, create a slice that is only evens. Next perform a reverse on it.

You already know how to create a slice of only odds, so you should be able to make a slice of only evens. I think you can figure out to create a slice that is a reverse of another slice, but if you can't, let me know and I'll give you some hints.
