What are the differences between decorators and functions in Python?

In Python, a function is a block of reusable code that performs a specific task. A decorator, on the other hand, is a function that modifies or enhances another function's behavior without changing its code.

Can you give me an example of a decorator?

Sure! Here's a simple example of a decorator that prints 'Hello' before calling the decorated function:

def my_decorator(func):
    def wrapper():
        print('Hello')
        func()
    return wrapper

@my_decorator
def say_name():
    print('My name is John')

say_name()  # This will print 'Hello' followed by 'My name is John'

How do decorators affect function arguments?

Decorators can be designed to accept arguments, allowing them to modify the behavior of the decorated function based on those arguments. You can achieve this by adding another layer of function definitions.

Are there built-in decorators in Python?

Yes, Python has several built-in decorators, such as @staticmethod, @classmethod, and @property, which are used to define methods in classes.
