What are the best practices for defining class methods in Python?

When defining class methods in Python, consider the following best practices: use clear naming conventions, keep methods focused on a single task, and utilize decorators like @classmethod and @staticmethod appropriately.

Can you explain the difference between @classmethod and @staticmethod?

Sure! A @classmethod receives the class as the first argument, allowing it to access class variables. A @staticmethod, on the other hand, does not take any special first argument and behaves like a regular function that belongs to the class's namespace.

When should I use class methods instead of instance methods?

Use class methods when you need to access or modify class state, or when you want to create factory methods that return an instance of the class. Instance methods are better for operations that pertain to individual object instances.

Are there any performance considerations I should keep in mind?

Yes, class methods can be slightly slower than instance methods due to the additional overhead of passing the class as the first argument. However, the difference is usually negligible unless you're calling them in a performance-critical loop.
