swap a string in python

  s1 = "Hello"
  s2 = "World"

s1, s2 = s2, s1
print(s1)
print(s2)

This code swaps the strings stored in the variables s1 and s2. It starts off by defining the strings "Hello" and "World" and storing them in the variables s1 and s2, respectively.

Next, on line 3, it uses a multiple assignment to set the variables s1 and s2 to their current swapped values, that is s2 and s1. Then, it prints out the contents of these two variables in order to verify that the strings have indeed been swapped.
