What is decorator chaining in Python?

Decorator chaining in Python allows you to apply multiple decorators to a single function, enhancing its behavior.

Can you give me an example of how to chain decorators?

Sure! Here's a simple example:

def decorator_one(func):
    def wrapper():
        print('Decorator One')
        func()
    return wrapper


def decorator_two(func):
    def wrapper():
        print('Decorator Two')
        func()
    return wrapper

@decorator_one
@decorator_two
def my_function():
    print('Hello, World!')

my_function()

This will print:

Decorator One
Decorator Two
Hello, World!

What happens if I change the order of the decorators?

Changing the order of decorators affects the execution sequence. The decorator closest to the function is applied first.

Can I chain decorators with parameters?

Yes, you can chain decorators with parameters by defining them as functions that return decorators.
