Python Python Collections (2016, retired 2019) Slices Slice Functions

problem with the even function

i tried to check if the length of the list is even , and if so then print it reversed with the slice but it didnt worked

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


def first_and_last_4(letter):
    adds = letter[:4]
    allt = adds + letter[-4:]

    return allt

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

def reverse_evens(lala):
    if len(lala) % 2 == 0:
        return lala[::-2]
    else:
        print("no")

Hey Daniel,

I'm not sure about adding the if else to check beforehand, but this code passes the final challenge

def reverse_evens(lala):
    lala_rev = lala[::2]
    return lala_rev[::-1]

Hope that helps, but keep messing around with it!
