What is decorator chaining in Python?

Can you explain what decorator chaining is in Python?

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

How do I implement decorator chaining in my code?

You can stack decorators by placing them one above the other, like this:

@decorator_one
@decorator_two
def my_function():
    pass

What are some practical use cases for decorator chaining?

Common use cases include logging, access control, and modifying function inputs or outputs.

Can you give me an example of chaining decorators?

Sure! Here's a simple example:

def uppercase_decorator(func):
    def wrapper(*args, **kwargs):
        return func(*args, **kwargs).upper()
    return wrapper

@uppercase_decorator
def greet(name):
    return f'Hello, {name}!'

print(greet('Alice'))  # Output: HELLO, ALICE!
