What are Python function decorators?

Can you explain what Python function decorators are?

Sure! Function decorators in Python are a way to modify or enhance functions or methods without changing their code.

How do you create a simple decorator?

To create a simple decorator, define a function that takes another function as an argument and returns a new function.

Can you give me an example of a decorator?

Absolutely! Here's a basic 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!')

What happens if I use multiple decorators?

When you use multiple decorators, they are applied from the innermost to the outermost, allowing for complex behavior.
