What are the differences between decorators and regular functions in Python 3.10?

In Python 3.10, decorators are special functions that modify the behavior of other functions. Unlike regular functions, decorators are applied using the '@' symbol and can take arguments.

Can you give me an example of a decorator?

Sure! 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()

How do decorators improve code readability?

Decorators can enhance readability by abstracting repetitive code patterns, allowing you to apply the same functionality across multiple functions without cluttering the core logic.

Are there any built-in decorators in Python?

Yes, Python has several built-in decorators like @staticmethod, @classmethod, and @property, which help in defining methods with specific behaviors.
