i don´t get it my challenge is not passing, i don´t know what i´m doing wrong any tips?

may be i don´t understand the challenge.

def first_4 (whatever):
    return whatever[:4]
def first_and_last_4 (whatever):

    a = whatever[:4]
    b = whatever[-4:]

    return a+b
def odds (whatever):

    x = list(whatever)

    return x[0::2]

1 Answer

The challenge is asking for every item with an odd index in a provided iterable. Currently your odd function returns a list starting at [0::2] and steps two numbers which would be 0,2,4,6 etc.

Just need to change the start of the slice.
