i dont understand the part return as a single value

i thought this should work but it kept saying the first task is not working now with my code

slices.py 
def first_4(iterable):
    first = []
    last = []
    reverse = []
    reverse = iterable[::-1]
    first = iterable[:4]
    last = reverse[:4]
    return "".join(first) + "".join(last)

It's not clear which task you are working on. The "first_4" function should simply return the first 4 items, but the code here is doing much more than that. If you've already passed that task, that function should be left as-is while you work on a different one.

And for the function that returns the first and last 4, the "last 4" part should not be reversed.

Also, you should not assume the iterable will be a list (by using "join"). It could just be a string.
