Example 1:- In this example, we will swap the values of two variables with each other. We will use a third variable to temporarily store the value.

 

 

Enter any number: 10
Enter any other number: 20
before swapping the values are…..
a= 10
b= 20
after the swapping values are….
a= 20
b= 10

 

Example 2:- Without using the third variable.

Python program to swap two variables without using a third variable.

a=int(input(‘Enter any number: ‘))
b=int(input(‘Enter any other number: ‘))
print(‘before swapping the values are…..’)
print(‘a=’,a)
print(‘b=’,b)
a=a+b
b=a-b
a=a-b
print(‘after the swapping values are….’)
print(‘a=’,a)
print(‘b=’,b)

 

Enter any number: 5
Enter any other number: 9
before swapping the values are…..
a= 5
b= 9
after the swapping values are….
a= 9
b= 5
