First 4 and last 4 values of an iterable, what output am I looking for?

I may be missing what output the question is looking for. I also tried ' '.join(a) to put first 4 and last four as one value. Thanks!

slices.py 
def first_4(item):
    item_list = list(item)
    copy_item_list = item_list[:]

    return copy_item_list[:4]

def first_and_last_4(item):
    item_list = list(item)
    copy_item_list = item_list[:]

    first_4 = copy_item_list[:4]
    last_4 = copy_item_lsit[-4:]

    a = first_4.extend(last_4)

    return a

I got first_and_last_4 to pass by returning a list made of the first 4 and last 4.

Did not use join to return them as a string.

Okay cool that is the way I'm doing it above. Do you see anything in my code I'm missing?

Thank you... always the little things. I also discovered in going through the forums that I was over complicating this. Thanks for the help!

One thing that has helped with code challenges is to try to make test to run with my code. Sometimes it'd take some time to figure out what they're testing for but I think in the end it's worth it.

You have a typo in spelling list here

last_4 = copy_item_lsit[-4:]
