trouble with returning slices here

the question was like: OK, this second one should be pretty similar to the first. Make a new function named first_and_last_4. It'll accept a single iterable but, this time, it'll return the first four and last four items as a single value.

slices.py 
def first_4(iterable):
    return iterable[:4]
def first_and_last_4(iterable):
    return iterable[:4 -4:]

You'll need to use concatenation instead. 

return iterable[:4] + iterable[-4:]
