  • revisiting our swap function
       - could we write a function that swaps two lists? (Hint: think about assigning to a slice)
          def list_swap(a, b):
             temp = a[:]
             a[:] = b[:]
             b[:] = temp[:]

       - could we ever write a function that swapped two ints (or floats, or strings)?

          def swap_int(num1, num2):

          - no.
