What are some common design patterns in Python?

Some common design patterns in Python include Singleton, Factory, Observer, and Decorator patterns. Would you like to know more about any specific one?

Can you explain the Singleton pattern?

Sure! The Singleton pattern ensures that a class has only one instance and provides a global point of access to it. It's useful when exactly one object is needed to coordinate actions across the system.

How do I implement the Factory pattern in Python?

To implement the Factory pattern, you create a factory class that has a method for creating objects. This method can return different types of objects based on input parameters.

What about the Observer pattern?

The Observer pattern allows an object, known as the subject, to maintain a list of dependents, called observers, and notify them of state changes. This is useful for implementing event-driven systems.
