Python 装饰器：深入理解功能增强
Let’s go beyond the basics to understand decorators in depth. Decorators are not just about "extra layers" but offer a sophisticated way to add functionality to functions dynamically, making them...
装饰器是高阶函数，用于动态添加功能而不修改原函数。常用语法为@符号，适用于访问控制、缓存、重试机制和输入验证。装饰器可带参数、支持堆叠，并可用于类方法。使用functools.wraps可保留原函数的元数据，使代码更灵活、模块化和优雅。
