Problem Statement
• In today's digital age, businesses are increasingly turning to e-commerce as a means of
reaching a wider customer base and offering convenient shopping experiences.
• Small to medium-sized businesses, particularly those in retail, are keen to establish an
online presence to remain competitive and cater to changing consumer preferences.
• The need arises for a robust e-commerce shopping cart system that can seamlessly
integrate with existing websites or standalone platforms, allowing businesses to showcase
and sell their products online.
• An E-commerce shopping cart is a software that lets customers select, store, and manage
items before buying them.
• It allows users to add, remove, and manage items for purchase, calculates total costs,
handles discounts or promotional offers, and provides a seamless checkout experience.

Code - Create the Product Class
class Product:
def __init__(self, id, name, price, description=''):
self.id = id
self.name = name
self.price = price
self.description = description
def __str__(self):
return f"{self.name} - ${self.price}"

Code - Create the Cartless Class
class CartItem:
def __init__(self, product, quantity):
self.product = product
self.quantity = quantity
def increase_quantity(self, amount=1):
self.quantity += amount
def decrease_quantity(self, amount=1):
self.quantity -= amount
if self.quantity < 0:
self.quantity = 0
def get_total_price(self):
return self.product.price * self.quantity
def __str__(self):
return f"{self.product.name} x {self.quantity} = ${self.get_total_price()}"

Code - Create the Shopping Cart Class
class ShoppingCart:
def __init__(self):
self.items = {}
def add_product(self, product, quantity=1):
if product.id in self.items:
self.items[product.id].increase_quantity(quantity)
else:
self.items[product.id] = CartItem(product, quantity)
def remove_product(self, product_id, quantity=1):
if product_id in self.items:
self.items[product_id].decrease_quantity(quantity)
if self.items[product_id].quantity == 0:
del self.items[product_id]
def get_total(self):
return sum(item.get_total_price() for item in self.items.values())
def __str__(self):
cart_contents = 'n'.join(str(item) for item in self.items.values())
return f"Shopping Cart:n{cart_contents}nTotal: ${self.get_total()}"

Code – Example Usage
# Create some products
apple = Product(id=1, name="Apple", price=0.50, description="Red Apple")
bread = Product(id=2, name="Bread", price=1.50, description="Whole
wheat")
# Create a shopping cart
cart = ShoppingCart()
# Add products to the cart
cart.add_product(apple, 3)
cart.add_product(bread, 1)
print(cart)
# Remove a product
cart.remove_product(1, 1)
print(cart)
