When should I use metaclasses in Python?

When should I use metaclasses in Python?

Metaclasses are a deep Python feature that allow you to customize class creation. You might use them when you need to enforce certain patterns or behaviors in your classes.

Can you give me an example of a situation where metaclasses are useful?

Sure! If you want to automatically register all subclasses of a base class, you can use a metaclass to do that during class creation.

Are there any downsides to using metaclasses?

Yes, metaclasses can make your code more complex and harder to understand. They should be used sparingly and only when necessary.

How do metaclasses differ from regular classes?

Metaclasses define the behavior of classes themselves, while regular classes define the behavior of instances. Essentially, a metaclass is a class of a class.
