🚀 Day 33 of #100DaysOfCode in Python: Delving into Decorators and Metaclasses

Welcome to Day 33! Today, we’re exploring two of Python’s more advanced features: decorators and metaclasses. These powerful concepts offer ways to modify and extend your code’s behavior, often leading to more efficient, elegant, and sophisticated programming patterns.

1. Understanding Decorators

Decorators in Python are a unique and powerful feature that allows for the modification or enhancement of functions and methods. They provide a clear and concise way to alter or extend the behavior of functions without changing their code.

• Function Decorators: These are applied to functions to modify their behavior. A common example is the @staticmethod or @classmethod decorators in class definitions.

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()

• Class Decorators: Applied to classes, they can modify or enhance class behavior.
