What are decorators in Python OOP?

What are decorators in Python OOP?

Decorators in Python are functions that modify the behavior of another function or method. In OOP, they can be used to enhance class methods.

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

Sure! Here's a simple example:

def my_decorator(func):
    def wrapper():
        print("Something is happening before the function is called.")
        func()
        print("Something is happening after the function is called.")
    return wrapper

class MyClass:
    @my_decorator
    def my_method(self):
        print("The method is called.")

In this example, my_decorator modifies my_method.

What happens if I don't use the decorator?

If you don't use the decorator, the method will execute normally without any modifications. The additional behavior defined in the decorator won't be applied.

Are there built-in decorators in Python?

Yes, Python has several built-in decorators like @staticmethod, @classmethod, and @property that are commonly used in OOP.
