How do I implement the Mediator Pattern in my code?

The Mediator Pattern is a behavioral design pattern that allows objects to communicate with each other without knowing about each other's internal states. Would you like a code example?

Yes, please provide a code example in Python.

Sure! Here's a simple example:

class Mediator:
    def notify(self, sender, event):
        pass

class ConcreteMediator(Mediator):
    def __init__(self, colleague1, colleague2):
        self.colleague1 = colleague1
        self.colleague2 = colleague2

    def notify(self, sender, event):
        if sender == self.colleague1:
            print("Colleague1 says: ", event)
            self.colleague2.receive(event)

class Colleague:
    def __init__(self, mediator):
        self.mediator = mediator

    def send(self, event):
        self.mediator.notify(self, event)

    def receive(self, event):
        print("Received event: ", event)

# Usage
colleague1 = Colleague(None)
colleague2 = Colleague(None)
mediator = ConcreteMediator(colleague1, colleague2)
colleague1.mediator = mediator
colleague2.mediator = mediator

colleague1.send("Hello from Colleague1!")

What are the benefits of using the Mediator Pattern?

The Mediator Pattern promotes loose coupling by keeping objects from referring to each other explicitly. It centralizes communication, making it easier to manage and modify interactions.
