How can I apply design patterns in my software development?

Design patterns are reusable solutions to common problems in software design. Which specific pattern are you interested in?

I'm curious about the Singleton pattern. How do I implement it?

The Singleton pattern ensures a class has only one instance and provides a global point of access. You can implement it by making the constructor private and providing a static method to get the instance.

Can you give me an example in Python?

Sure! Here's a simple example:

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 other design patterns I should know about?

Some other important design patterns include Factory, Observer, and Strategy patterns. Would you like to explore any of these?
