Python decorators in classes

Python decorators are a powerful and flexible feature that allows you to modify the behavior of functions or methods without changing their source code. They can be used in classes to enhance or modify the behavior of methods, and they offer a clean and modular way to add functionality to your code.
In this tutorial, we will explore Python decorators in the context of classes, providing you with a clear understanding of how to use them and why they are valuable. We will also include code examples to illustrate various use cases.
In Python, a decorator is a function that wraps another function or method, modifying its behavior. Decorators are commonly used for tasks such as logging, authentication, access control, and more. They provide a way to separate concerns and keep code modular and clean.
Decorators are often applied using the @decorator_name syntax, just above the function or method definition. When the decorated function or method is called, it is executed with the additional behavior provided by the decorator.
Decorators can also be used to modify the behavior of methods within a class. To create a decorator for a class method, you need to define the decorator function and apply it to the method you want to enhance.
Here's a step-by-step guide with code examples:
Let's start by creating a simple decorator that logs the method name before and after it is called.
Now, we'll create a class with a method and apply our decorator to it.
