Too Long; Didn't Read

The Singleton Design Pattern is a way of making sure that a class only has one instance and can be accessed globally. In Python, you can do this by making a class with a private constructor and a static method that returns the instance. This is great for things like database connections or settings where you only need one instance. When it comes to testing, singletons are a big no-no. They create a tight coupling between classes.
