Act I: The Hook

Imagine a single piece of code that controls everything in your application: user authentication, database connections, email notifications, and even the UI logic. It seems convenient at first, but soon it becomes a massive, unmaintainable beast. This is known as "The God Object".

Act II: Mental Model

To understand how to dismantle the God Object, we must introduce the SOLID principles, specifically the Single Responsibility Principle (SRP). Think of your application as a restaurant. If the chef is also taking orders, serving food, and handling payments, chaos ensues. Instead, responsibilities must be divided among specialized roles.

Act III: The Rabbit Hole

Now, look at the code snippet provided below. It represents a God Object in a hypothetical e-commerce system. Your task is to identify its multiple responsibilities and apply the SOLID principles to break it down.

class ECommerceSystem:
    def process_order(self, order):
        # process payment
        # update inventory
        # send confirmation email
        pass
