function returns the right value but I get a bummer message.

My code return [5,3,1] like it should but still the assignment says: bummer didnt get the right value from reverse_evens.

slices.py 
def first_4(list):

    return list[:4]


def first_and_last_4(list):

    new_list = list[:4] + list[-4:]

    return new_list


def odds(list):

    return list[1::2]


def reverse_evens(list):

    reversed_list = list[::-1]
    new = reversed_list[::2]

    return new

Hi Marco, you've almost got it except you have it in the wrong order, the challenge requires that you get the even values first and then reverse it, like so:

def reverse_evens(list):

    reversed_list = list[::2]
    new = reversed_list[::-1]

    return new

Hope that helps!!
