Not sure what its asking here.

When I run this code outside of the challenge I get what I believe to be the correct result.

e.g if I had a list of numbers from 1 - 10 and ran it through the odds function It would return the numbers (2, 4, 6, 8, 10) with the Index being odd numbers. (1, 3, 5, 7, 9).

but in the challenge it get "Didn't get the right value for odds".

Any idea what I am doing wrong?

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

def first_and_last_4(items):
    first4 = items[:4]
    last4 = items[-4:]
    both = first4 + last4
    return(both)

def odds(items):
    oddItems = items[1::2]
    return[oddItems]

never mind, I see that I have used [] for return.

Also, "return" is not a function, so you don't need parentheses around the result either:

    return both  # instead of: return(both)
