Can you give an example of a design pattern?

Can you give me an example of a design pattern?

Sure! One common design pattern is the Singleton pattern. It ensures a class has only one instance and provides a global point of access to it.

How does the Singleton pattern work?

The Singleton pattern restricts instantiation of a class to one object. It typically involves a private constructor and a static method to get the instance.

Can you provide a code example?

Certainly! Here's a simple example in Python:

class Singleton:
    _instance = None

    def __new__(cls):
        if cls._instance is None:
            cls._instance = super(Singleton, cls).__new__(cls)
        return cls._instance

What are some use cases for the Singleton pattern?

It's often used for logging, configuration settings, and managing shared resources like database connections.
