495 PointsWHY IS THIS WRONG?
I dont know what to put in the second slice
def first_4(list1):
return list1[:4]
first_4([2, 7, 9, 4, 6])
def first_and_last_4(list2)
return my_list[1:5]
return my_list[:5]
first_and_last4([3, 7, 9, 5, 4, 9, 1, 6, 6, 4, 0])

First and foremost, you cannot return twice from a function. As soon as python runs return it stops executing the function. Nothing else will be run. So you'll need to combine the slices first, and then return them.
Second - don't forget the colon after the first line of your function!
Last you need to figure out how to get the last four items of the iterable. Right now your two return statements return the second through fifth, and then the first through fifth. Neither of those are right. You know how to get the first four (you did it in part 1), now you need to get the last four. You might need to watch the video again to remind yourself how to get items from the end of an iterable.
Good luck, and let us know how it goes!
Cheers
