There are four parts to this task:

  • define function named first_and_last_4 that accepts an iterable
  • get first 4 item (a slice would work nicely)
  • get last 4 items (again a slice)
  • return both slices
def first_and_last_4(iter1):
    first4 = ???
    last4 = ???
    return first4 + last4

Can you define the two needed slices?
