(e.g., Adapter, Bridge, Composite, Decorator, Facade)

Creational patterns abstract the instantiation process. They help make a system independent of how its objects are created, composed, and represented.

Every time you add a new payment method (like Apple Pay or Crypto), you have to modify the Checkout class. This violates the Open/Closed Principle (code should be open for extension, but closed for modification). The Solution: The Strategy Pattern

That's why we're excited to dive into design patterns, exploring the most popular and useful patterns, and providing you with PDF and GitHub resources to help you learn and implement them in your own projects. Each chapter follows a structured approach: Every time

By using the , we isolate the payment algorithms into separate classes that share a common interface.

The book covers the three main categories of design patterns defined by the "Gang of Four" (GoF): By using the , we isolate the payment

Originating from the "Gang of Four" (GoF) book in 1994, these patterns are generally divided into three distinct categories:

Explaining concepts like the Strategy pattern through simple, daily scenarios. Clear diagrams: Visualizing class interactions.

class CreditCardPayment: def pay(self, amount): return f"Paid $amount using Credit Card." class PayPalPayment: def pay(self, amount): return f"Paid $amount using PayPal." class ShoppingCart: def __init__(self, payment_strategy): self.payment_strategy = payment_strategy def checkout(self, amount): print(self.payment_strategy.pay(amount)) # Usage cart_one = ShoppingCart(CreditCardPayment()) cart_one.checkout(150) cart_two = ShoppingCart(PayPalPayment()) cart_two.checkout(45) Use code with caution.
