Advanced Python Decorators: Power Up Your Code.

Understanding Python Decorators

Decorators are a powerful feature in Python that allow you to modify the behavior of functions or classes.

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!")

Practical Use Cases

Decorators are commonly used for logging, timing, authentication, and more.
