Python program for swapping the value of two integers

Learn how to swap the value of two integers using third variable using Python program. By Anuj Singh Last updated : January 04, 2024

Problem statement

Given two numbers, write a Python program to swap them.

Algorithm to swap two numbers

Storing the value of one variable (x) in a different variable (namely temporary - temp).
Then changing the value of x by copying the value of y.
Then changing the value of y by copying the value of temp.

Three simple steps, three simple variables and its all done.

Python program for swapping the value of two integers

# Code toto to swap two numbers

# Input the numbers
x = int(input("ENTER THE VALUE OF X: "))
y = int(input("ENTER THE VALUE OF Y: "))

# Printing numbers before swapping
print("Before swapping:")
print("X :", x, " Y :", y)

# Swapping the numbers
temp = x
x = y
y = temp

# Printing numbers after swapping
print("After swapping:")
print("X :", x, " Y :", y)

Output

The output of the above example is:

RUN 1:
ENTER THE VALUE OF X: 100
ENTER THE VALUE OF Y: 200
Before swapping:
X : 100  Y : 200
After swapping:
X : 200  Y : 100

RUN 2:
ENTER THE VALUE OF X: 108
ENTER THE VALUE OF Y: 1008
Before swapping:
X : 108  Y : 1008
After swapping:
X : 1008  Y : 108

To understand the above program, you should have the basic knowledge of the following Python topics:
