The Power of Python Decorators(Python Core in Action 16)
Master Python decorators to simplify authentication, logging, input validation, and caching. Boost code efficiency and readability with these essential techniques.
Welcome to the "Python Core in Action" Series
Decorators have always been a useful and classic feature in Python, widely used in engineering tasks like logging, caching, and more.
However, I've noticed that many people, especially beginners, are often intimidated by decorators because they seem complex, thinking they are "too fancy to learn." But in reality, they aren't as difficult as they seem.
In today's lesson, I'll introduce decorators by first revisiting functions and closures. Then, I'll explain the concept, syntax, and basic usage of decorators. Finally, we'll reinforce your understanding with real-world examples from engineering.
Let's dive in!
