Not sure how to get last 4 items

I know the function isn't complete. I don't know how to get the last 4 items.

slices.py 
def first_4(arg):
    return arg[0:4]

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

def first_and_last_4(ite):
    return ite[0:4]

Hi Kenneth!

Use a plus sign, so for example if I used arg for my argument inside the func., I can say:

return arg[:4] + arg[-4:]

Remember, when we use a negative, it counts backwards from that number; so this will give us the sum of the two.
