Python program to swap two variables -By using XOR method

Python / Operators in Python

161

We can also use the bitwise XOR method for swapping two variables. The XOR of two variables, P and Q, will return the number which has all the bits as 1 whenever the bits of the P and Q variables differ.

Such as XOR of 4 (in binary 0100) and 6 (in binary 0110) is 1010.

XOR of 2 (in binary 0010) and 8 (in binary 1000) is 1010.

Program:

P = int( input("Please enter value for P: "))  
Q = int( input("Please enter value for Q: "))  
   
# To Swap the values of two variables using XOR  
P = P ^ Q  
Q = P ^ Q  
P = P ^ Q  
   
print ("The Value of P after swapping: ", P)  
print ("The Value of Q after swapping: ", Q)  

Output:

Please enter value for P:  12
Please enter value for Q:  10
The Value of P after swapping: 10
The Value of Q after swapping: 12
