what am I doing wrong? python reverse evens
It's probably something simple but I'm stumped
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): if len(item) % 2 == 0: return item[:-1:-2] if len(item) % 2 == 1: return item[:-2:-2]

You're close, but instead of the stop and step (arguments 2 and 3) of the slice, you need to specify the start and step (arguments 1 and 3).
You may also need to exchange the offsets for each case.
