Here is a Python program to swap lists for lists

import random

def swap(a, b):
    """
    Swap the values of a and b.

    >>> swap(1, 2)
    >>> swap(1, 2)
    >>> swap(1, 2)
    """
    temp = a
    a = b
    b = temp

# Enter the two lists
a = [1, 2, 3]
b = [4, 5, 6]

# Calling the function
print((swap(a, b)))

#Example Output
# None

#Remember to inspect code for bugs.
