When should I use singletons in my code?

Singletons are useful when you need to ensure a class has only one instance and provide a global point of access.

Can you give me an example of a situation where a singleton is beneficial?

Sure! A common use case is for managing database connections, where you want to limit the number of connections.

Are there any downsides to using singletons?

Yes, they can introduce global state into your application, making it harder to test and maintain.

How can I implement a singleton in Python?

You can use a class with a private constructor and a class method to control the instance creation.
