What are the different types of decorators in Python?

In Python, decorators are functions that modify the behavior of another function. The main types include:

1. Function decorators
2. Class decorators
3. Method decorators
4. Built-in decorators like @staticmethod and @classmethod.

Can you explain function decorators in more detail?

Sure! Function decorators are used to wrap another function, allowing you to add functionality before or after the wrapped function runs. They are defined using the '@decorator_name' syntax above the function definition.

What about class decorators? How do they work?

Class decorators are similar to function decorators but are applied to classes. They can modify or enhance class behavior, such as adding new methods or properties.

Can you give me an example of a custom decorator?

Absolutely! 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

@my_decorator
def say_hello():
    print('Hello!')

say_hello()
