Swap Two Numbers Without Using a Third Variable

❮ Previous Next ❯

A Python program to swap two numbers without using a third variable.

Here’s a explanation of the code in points:

Function Definition:
- swap_number(num1, num2) swaps two numbers by returning them as a tuple (num2, num1).
User Input:
- The program takes two numbers from the user using input() and converts them to integers using int().
Swapping:
- The swap_number() function is called, returning the swapped values.
- The returned tuple (num2, num1) is unpacked and assigned to num1 and num2.
Output:
- The program prints the swapped values using print().

Example:

Input: num1 = 5, num2 = 10
Output: First number = 10, Second number = 5

Program:

def swap_number(num1,num2):
    return num2, num1
num1=int(input("Enter a number First:"))
num2=int(input("Enter a number Second:"))
num1,num2=swap_number(num1,num2)
print(f"After swapping: First number = {num1}, Second number = {num2}")
