python decorator for class method

Decorators are a powerful feature in Python that allow you to modify or extend the behavior of functions or methods. In this tutorial, we'll explore how to use decorators specifically for class methods. Class method decorators can be handy for tasks such as logging, access control, and performance monitoring.
In Python, a class method is a method that is bound to the class and not the instance of the class. You can define a class method using the @classmethod decorator. Here's a simple example:
In this example, print_class_variable is a class method because it is decorated with @classmethod. Now, let's explore how we can use decorators to enhance the functionality of class methods.
In this example, class_method_decorator is a decorator function that takes a method as an argument and returns a new method (wrapper) that adds some functionality before and after the original method is called.
Now, let's use our decorator to enhance the functionality of a class method:
Here, we use the @class_method_decorator decorator to modify the behavior of the print_class_variable method.
When you run this code, you should see the following output:
This demonstrates that the decorator successfully added functionality before and after the original class method was executed.
Decorators provide a flexible and reusable way to enhance the behavior of class methods in Python. By understanding how decorators work and creating custom decorators, you can efficiently manage cross-cutting concerns in your code. Experiment with different use cases and explore more advanced decorator patterns to further extend the capabilities of your Python classes.
