Python program to swap two variables

Python Code:

# Read inputs from the user

x = input('Enter value of x: ')

y = input('Enter value of y: ')

print('Value of x before swapping: ', x)

print('Value of y before swapping: ', y)

# using temporary variable to swap values

temp = x

x = y

y = temp

print('Value of x after swapping: ', x)

print('Value of y after swapping: ', y)

Output of program:

Enter value of x: 10 Enter value of y: 20 Value of x before swapping: 10 Value of y before swapping: 20 Value of x after swapping: 20 Value of y after swapping: 10
