Bummer! Didn't get the right values from `reverse_evens`.

I tried different version also but its still not working for me maybe my code is not correct but in my local machine its printing exactly same as it is asking in question but don't know why is it still keep saying Bummer! Didn't get the right values from reverse_evens.

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

def first_and_last_4(y):
    return first_4(y) + y[-4:]

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

def reverse_evens(z):
    a = z[::-1]
    return a[::2]

num = list(range(1,6))

I'm not exactly sure why, but you need to have the variable a = z[::2] and then return it in reverse like return a[::-1]

both work the same in the shell, but the challenge requires it the way I have described.

Thanks it works :)
