does python have a swap funciton code example

Example 1: swapping variables in python

a = 1
b = 2

a, b = b, a
# a = 2 , b = 1

Example 2: python swap function

def swap0(s1, s2):
    assert type(s1) == list and type(s2) == list
    tmp = s1[:]
    s1[:] = s2
    s2[:] = tmp
    
# However, the easier and better way to do a swap in Python is simply:
s1, s2 = s2, s1
