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)
Output
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.
