"Swap Two Numbers Using Temp Variable in Python"
Title: Python Program to Swap Two Numbers Using Temp Variable | 1st PUC Computer Science

Description:

In this video, we will learn how to swap two numbers in Python using a temporary variable. Swapping is a basic concept in programming that involves exchanging the values of two variables.

In this program:

We'll take two numbers as input from the user.
We'll use a temporary variable to store one of the numbers.
We'll then swap the values of the two numbers using the temporary variable.
Finally, we'll print the swapped values to verify the result.
Key Concepts Covered:
Input and Output in Python
Using a temporary variable for swapping
Simple variable assignment in Python

Program to swap two numbers using a temporary variable

Input two numbers
num1 = float(input("Enter the first number: "))
num2 = float(input("Enter the second number: "))

Display the original values
print("\nBefore swapping:")
print("First number:", num1)
print("Second number:", num2)

Swap the values using a temporary variable
temp = num1
num1 = num2
num2 = temp

Display the swapped values
print("\nAfter swapping:")
print("First number:", num1)
print("Second number:", num2)

output

Enter the first number: 10
Enter the second number: 20

Before swapping:
First number: 10.0
Second number: 20.0

After swapping:
First number: 20.0
Second number: 10.0


Why Learn This?
Swapping values is a common operation in many algorithms. Understanding how to do it efficiently using a temporary variable will help you solve more complex problems in Python.
