What are decorators in classes and how do they work?

Decorators in classes are special functions that modify or enhance the behavior of class methods or properties. They are often used for logging, access control, or modifying input/output.

Can you give me an example of a decorator in a class?

Sure! Here's a simple example:

def my_decorator(func):
    def wrapper(*args, **kwargs):
        print('Before calling the function')
        result = func(*args, **kwargs)
        print('After calling the function')
        return result
    return wrapper

class MyClass:
    @my_decorator
    def my_method(self):
        print('Inside the method')

obj = MyClass()
obj.my_method()

What happens when I call my_method in this example?

When you call my_method, the output will be:

Before calling the function
Inside the method
After calling the function
``` This shows how the decorator wraps the method call.

Are there any built-in decorators in Python?

Yes, Python has several built-in decorators like @staticmethod, @classmethod, and @property that provide specific functionalities.
