@Marvin what's the best practice of decorating class methods?

Decorating class methods in Python can add functionality to methods in a clean and readable way. Here are some best practices when using decorators for class methods: ### 1. Use

classmethod

and

staticmethod

Appropriately -

classmethod

: Use when a method needs to access or modify the class state. The first parameter must be

cls

. -

staticmethod

: Use when a method does not need access to the instance or class. No

self

or

cls

parameter is required. ### 2. Creating Your Own Decorators - Ensure your decorator accepts

self

or

cls

where appropriate. - Use

functools.wraps

to maintain the original method's metadata. ### 3. Chaining Decorators - Decorate the methods from the innermost to the outermost if you use multiple decorators. ### 4. Storing Decorators as Methods - If the decorator behavior belongs to the class logic, consider storing the decorator itself as a method of the class. ### Example

python
import functools

class Myclass:
    
    @classmethod
    def my_class_method(cls):
        print(f"This is a class method. cls: {cls}")
    
    @staticmethod
    def my_static_method():
        print("This is a static method.")
        
    def my_instance_method(self):
        print(f"This is an instance method. self: {self}")
    
    def method_decorator(decorator_param):
        def decorator(func):
            @functools.wraps(func)
            def wrapper(self, *args, **kwargs):
                print(f"Decorator param: {decorator_param}")
                return func(self, *args, **kwargs)
            return wrapper
        return decorator
    
    @method_decorator(decorator_param="example")
    def my_decorated_method(self):
        print(f"Decorated method called. self: {self}")

# Example Usage
obj = Myclass()
obj.my_class_method()
obj.my_static_method()
obj.my_instance_method()
obj.my_decorated_method()

### Best Practices Summary 1. Use appropriate method types (

staticmethod

,

classmethod

). 2. Maintain method signatures using

functools.wraps

in custom decorators. 3. Use decorators in a readable order when stacking multiple decorators. 4. Encapsulate decorator logic within the class if tightly coupled with class functionalities. Remember, readability and clarity are key, so always document and explain your decorators to keep your codebase maintainable. If you need further details, consult the Python Decorators documentation or relevant PEPs.
