How do I implement design patterns in my project?

To implement design patterns, first identify the problem you're facing, then choose a suitable pattern like Singleton or Observer.

Can you give me an example of the Singleton pattern?

Sure! The Singleton pattern ensures a class has only one instance and provides a global point of access to it. 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 common design patterns I should know?

Some common design patterns include:

1. Singleton
2. Factory
3. Observer
4. Strategy
5. Decorator Each serves different purposes in software design.

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

Consider the specific problem you're trying to solve, the context of your application, and the trade-offs of each pattern. It's often helpful to review the intent and structure of each pattern.
