Python. Write a function swap_lists that takes in two lists and swap their elements in place. You can not use another list. You can not return lists. Input lists have the same size.

def swap_lists(alist1, alist2):

"""Swaps content of two lists.

Does not return anything.

>>> list1 = [1, 2]

>>> list2 = [3, 4]

>>> swap_lists(list1, list2)

>>> print(list1)

[3, 4]

>>> print(list2)

[1, 2]

>>> list1 = [4, 2, 6, 8, 90, 45]

>>> list2 = [30, 41, 65, 43, 4, 17]

>>> swap_lists(list1, list2)

>>> print(list1)

[30, 41, 65, 43, 4, 17]

>>> print(list2)

[4, 2, 6, 8, 90, 45]
