What are some examples of function decorators in Python?

Can you explain what function decorators are in Python?

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

Can you give me some examples of how to use decorators?

Absolutely! A common example is the @staticmethod decorator, which allows a method to be called on a class without an instance.

What about a custom decorator? How would I create one?

You can create a custom decorator by defining a function that takes another function as an argument and returns a new function that adds some functionality.

Can you show me a simple custom decorator example?

Certainly! Here's a simple 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!')

say_hello()
