Swapping of Two Numbers in Python Using Temp Variable

In this blog, we will be explaining how to write swapping of two numbers in python using the temp variable.

What is Swapping?

Swapping means taking the value from variable a to variable b and vice versa. In other words, ” swapping means replacing values of a variable with other variables. “

For a moment, forget about programming. Just assume we have two containers, A and B. And now we need to take the content of container A into container b and vice versa.

Program to Swap Two Numbers in Python using temp variable

Let’s write a program that Swaps Two Numbers.

Source Code with Explanation

x = int(input("Enter the Value of x:"))
y = int(input("Enter the Value of y:"))

temp = x
x = y
y = temp

print("Values after swapping x=",x,"y=",y)
Enter the Value of x: 10
Enter the Value of y: 20
Values after swapping x= 20 y= 10

To write a swapping program in python, a temporary variable is used as the temporary storage. 

  • The first content of the variable “x” goes into a temp variable
  • Then the content of variable “y” in a variable
  • Then the content of the temp variable goes to y.
  • If you print the result, the value is swapped.
