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?

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 does the Factory pattern work?

The Factory pattern defines an interface for creating an object but allows subclasses to alter the type of objects that will be created. It promotes loose coupling in your code.

What about the Observer pattern?

The Observer pattern is a behavioral design pattern where an object, called the subject, maintains a list of its dependents, called observers, and notifies them of state changes, usually by calling one of their methods.
