In this tutorial, we will learn how to program "How to Find the Product of Two Numbers Using Recursion in Python". The objective is to compute the product of two numbers using a recursive approach. This tutorial will guide you step by step through the process of multiplying two numbers with recursion. 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 skills and improve your coding abilities.

This topic is straightforward and easy to understand. Simply follow the instructions provided, and you’ll complete it with ease. The program will guide you step by step through the process of finding the product of two numbers using recursion. 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.

def product(a, b):
    # Ensure 'a' is the larger number for efficiency
    if a < b:
        return product(b, a)
    elif b != 0:
        return a + product(a, b - 1)
    else:
        return 0
 
while True:
    print("\n============== Find the Product of Two Numbers Using Recursion ==============\n")
    
    a = int(input("Enter first number: "))
    b = int(input("Enter second number: "))
    
    print("Product is:", product(a, 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 calculates the **product of two numbers using recursion** instead of the multiplication operator. It repeatedly adds one number (`a`) to itself based on the value of the other number (`b`). To optimize performance, the function ensures that the smaller number is used for recursion. The program keeps prompting the user to enter two numbers, displays their product, and allows the user to continue or exit the program.

Output:

There you have it we successfully created How to Find the Product of Two Numbers Using Recursion 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!
