7,548 PointsCould someone advise if it is possible to slice around items in a list? I'm having trouble wrapping my head this concept
I have exhausted my brain of ways to try this. I'm not looking for answers to this Challenge, just some support in understanding the slice concept a little better. I've tried to extend additional variables, and while it would produce the correct answer as far as the numbers are concerned it would only work for the specific instance I created, not for any iterable provided as an argument.
def first_4 (first_list = list(range(10))):
return first_list[:4]
def first_and_last_4(first_list = list(range(10))):
return first_4([4:])

For task 2, if you want to call your task 1 function you'll need to pass along the argument to it. You won't need a slice for the first part because the other function does that for you. But you will need to combine that with a separate slice to add on the "last 4" part.
