How to Swap Two Numbers Without Using a Third Variable in Python
In this tutorial, we will learn how to program "How to Swap Two Numbers Without Using a Third Variable in Python". The objective is to swap two numbers without using a third variable. This tutorial will guide you step by step through methods for swapping two numbers efficiently. By the end of this tutorial, you will have a solid understanding of how to implement this task effectively in Python, helping you strengthen your problem-solving abilities and improve your coding skills.
This topic is straightforward and easy to understand. Simply follow the instructions provided, and you will complete it with ease. The program will guide you step by step through the process of swapping two numbers without using a third variable. So, let’s dive into the coding process!
Getting Started:
First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.
Creating Main Function
This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.- while True:
- print("\n============== Swap Two Numbers Without Using a Third Variable ==============\n")
- a = int(input("Enter value of first variable: "))
- b = int(input("Enter value of second variable: "))
- # Swap without a third variable
- a = a + b
- b = a - b
- a = a - b
- print("After swapping: a is:", a, " b is:", b)
- # Ask user if they want to try again
- opt = input("\nDo you want to try again? (yes/no): ").strip().lower()
- if opt == 'no':
- print("Exiting program...")
- break
- elif opt != 'yes':
- print("Invalid choice. Exiting program...")
- break
This Python program swaps the values of two numbers without using a third variable. It prompts the user to enter two numbers, performs the swap using arithmetic operations (`a = a + b; b = a - b; a = a - b`), and then displays the swapped values. The user can repeat the process or exit the program.
Output:
There you have it we successfully created How to Swap Two Numbers Without Using a Third Variable in Python. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
