In this blog post,we are going to learn how to swap two variables by using a temporary variable and
swap two variables without using any temporary variable.
Python Program to Swap Two Variables Using temporary variable:-
# Python program to swap two variables Using temporary #variable or Third variable # If you want to take input from the user then # var1 = input('Enter value of x: ') # var2 = input('Enter value of y: ') var1 = 20 var2 = 40 # create a temporary variable and swap the values var_temp = var1 var1 = var2 var2 = var_temp print('The value of var1 after swapping: {}'.format(var1)) print('The value of var2 after swapping: {}'.format(var2))
Output:-
The value of x after swapping: 40 The value of y after swapping: 20
Python Program to Swap Two Variables without Using temporary or third variable:-
# Python program to swap two variables without Using #temporary or Third variable # If you want to take input from the user then # var1 = input('Enter value of x: ') # var2 = input('Enter value of y: ') var1 = 20 var2 = 40 # create a temporary variable and swap the values var1=var1+var2 var2 = var1-var2 var1 = var1-var2 print('The value of var1 after swapping: {}'.format(var1)) print('The value of var2 after swapping: {}'.format(var2))
output:-
The value of var1 after swapping: 40 The value of var2 after swapping: 20
