What are some best practices for using design patterns in Python?

When using design patterns in Python, it's important to keep your code simple and readable. Favor composition over inheritance, and ensure that your patterns are appropriate for the problem at hand.

Can you give me an example of a design pattern in Python?

Sure! The Singleton pattern ensures a class has only one instance and provides a global point of access to it. Here's a simple implementation:

class Singleton:
    _instance = None

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

What are the advantages of using design patterns?

Design patterns provide proven solutions to common problems, improve code readability, and facilitate communication among developers by providing a shared vocabulary.

How do I choose the right design pattern for my project?

Consider the specific problem you're trying to solve, the complexity of your application, and the patterns that best fit your needs. It's also helpful to review existing codebases for inspiration.
