What is decorator chaining in Python 3.10?

Can you explain what decorator chaining is in Python 3.10?

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

How do I implement decorator chaining in my code?

You can stack decorators above a function definition. For example:

@decorator_one
@decorator_two
def my_function():
    pass

Are there any limitations or best practices for using decorator chaining?

Yes, be cautious of the order of decorators, as it affects the final behavior. Always test to ensure the desired outcome.

Can you give me a practical example of using decorator chaining?

Sure! Here's a simple example:

def uppercase_decorator(func):
    def wrapper():
        return func().upper()
    return wrapper

@uppercase_decorator
def greet():
    return 'hello'

print(greet())  # Outputs: HELLO
