1. Scenario

An online shopping platform needs a system to process orders. When a customer places an order, the system should:

• Store the customer's name (string).

• Store the number of items ordered (int).

• Store the total price, including tax (float).

• Check if the customer is eligible for free shipping (boolean).

The system should calculate the final amount after applying tax and determine if free shipping is applicable for orders above ₹1000.

2. Problem Statement

Develop a Python program that takes a customer's name, the number of items purchased, and the total amount before tax. The program should:

1. Calculate the total cost after adding GST (18%).

2. Check if the order qualifies for free shipping (orders above ₹1000).

3. Display the order summary with all details.

3. Why We Need This Use Case

In modern e-commerce platforms, order processing is a critical component. Whether you're running a small online store or a large retail business, being able to calculate costs, apply taxes, and determine shipping eligibility in real-time is essential.
This use case showcases how basic Python data types (int, float, str, bool) are applied in a real-world business scenario to:

• Collect and validate customer input

• Perform tax calculations

• Determine shipping eligibility

• Display a clean, user-friendly order summary

It also introduces beginner programmers to structured, modular, and functional thinking using Python.

4. When We Need This Use Case

This use case is useful when:

• You're building a simple checkout/order processing module for an e-commerce application.

• You want to teach or learn how Python handles user input and performs calculations.

• You need to create testable scripts for business simulations or educational tools.

• You’re developing a system that needs to log customer details and transaction summaries.
