Reverse and print even index.

I do not understand why this is not working and there are no ways to diagnose whats going wrong on this challenge, it just says "bummer, try again"

What am I doing wrong???

slices.py 
def first_4(item):
    return item[:4]
def first_and_last_4(item):
    return item[:4] + item[-4:]
def odds(item):
    return item[1::2]
def reverse_evens(item)
    even = item[::2]
    return even[::-1]

You have the answer correct, but you're missing a colon in your last function definition.

def reverse_evens(item):

Also, FYI you can combine those two actions at the end.

item[::2][::-1]
