How can I implement other design patterns in my project?

There are several design patterns you can implement, such as Singleton, Factory, and Observer. Which one are you interested in?

I'm particularly interested in the Factory pattern. Can you explain how it works?

Sure! The Factory pattern allows you to create objects without specifying the exact class of the object that will be created. It uses a factory method to handle the instantiation.

Can you provide a code example of the Factory pattern?

Absolutely! Here's a simple example in Python:

class Dog:
    def speak(self):
        return "Woof!"

class Cat:
    def speak(self):
        return "Meow!"

class AnimalFactory:
    @staticmethod
    def get_animal(animal_type):
        if animal_type == "dog":
            return Dog()
        elif animal_type == "cat":
            return Cat()
        return None

# Usage
animal = AnimalFactory.get_animal("dog")
print(animal.speak())  # Output: Woof!
