Design an ECommerce Order System with Cart Items and Payments

You will design a small e-commerce order system that uses composition to combine Product, CartItem, Cart, Order, and PaymentProcessor classes. The system must: - Represent items with a Product and quantity using CartItem. - Aggregate CartItems in a Cart and compute subtotal, apply discounts, and tax to produce a final amount in cents. - Apply a 10% discount on the subtotal when subtotal exceeds 10000 cents ($100). - Apply tax at 8% to the discounted subtotal. - Use a PaymentProcessor to simulate payments. Supported payment methods are 'card' and 'paypal'. Payment succeeds only when the final amount is greater than zero and the method is supported. - Expose a function process_order(items, payment_method) where items is a list of tuples (name, price_cents, quantity). The function builds the objects using composition and returns a tuple (paid: bool, total_cents: int). Implement missing parts in the starter code to make process_order behave as described. Handle edge cases reasonably: negative quantities should be treated as zero, empty carts result in no payment (paid=False, total=0).

Implement a composed system to calculate order totals (with discounts and tax) and simulate payment processing using multiple collaborating classes.

- Prices and quantities are integers (cents for price). Negative quantities should be treated as zero. - Discount threshold: 10000 cents. Discount rate: 10%. - Tax rate: 8%. - Supported payment methods: 'card', 'paypal'. - Use composition (Cart composed of CartItem objects that reference Product objects).
