Python program to swap two variables
224
In this tutorial, we will learn how to swap two variables in a Python program. Suppose we have two variables, P and Q; We have to write a Python program for swapping their values. We will also discuss the different methods in Python for doing this task.
Program:
P = int( input("Please enter value for P: ")) Q = int( input("Please enter value for Q: ")) # To swap the value of two variables # we will user third variable which is a temporary variable temp_1 = P P = Q Q = temp_1 print ("The Value of P after swapping: ", P) print ("The Value of Q after swapping: ", Q)
Output:
Please enter value for P: 13 Please enter value for Q: 43 The Value of P after swapping: 43 The Value of Q after swapping: 13
Explanation:
In this method, the naïve approach will store the value of the P variable in a temporary variable, and then it will assign the variable P with the value of the Q variable. Then, it will assign the value of the temporary variable to the Q variable, which will result in swapping the values of both the variable.
