How can I chain decorators in Python?

Chaining decorators in Python allows you to apply multiple decorators to a single function. You can stack them by placing one decorator above the other.

Can you show me an example of chaining decorators?

Sure! Here's a simple example:

def decorator_one(func):
    def wrapper(*args, **kwargs):
        print('Decorator One')
        return func(*args, **kwargs)
    return wrapper


def decorator_two(func):
    def wrapper(*args, **kwargs):
        print('Decorator Two')
        return func(*args, **kwargs)
    return wrapper

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

my_function()

When you call my_function(), it will print:

Decorator One
Decorator Two
Hello, World!

What happens if I change the order of the decorators?

If you change the order of the decorators, the output will change accordingly. The decorator closest to the function will be applied first. For example, if you switch the order, @decorator_two will execute before @decorator_one.

Are there any limitations to chaining decorators?

Yes, there can be limitations, such as increased complexity and potential for confusion in debugging. It's important to ensure that the decorators are compatible and that they don't interfere with each other's functionality.
