内容简介

别浪费时间让Python去适应你在其他语言中学到的模式。尽管Python的简单性可迅速提高你的工作效率，但这往往意味着你并未运用该语言所提供的所有特性。通过这本实践指南的更新版，你将学会如何利用很好理念来编写有效的现代Python 3代码。发现并应用超出你过往经验之外的Python 3惯用特性。作者Luciano Ramalho将带你了解Python的核心语言特性和库，并教你如何使代码更短、更快、更具可读性。新版进行了重大的更新，共包含五部分，每部分都相当于一本迷你书：数据结构：序列、字典、集合、Unicode和数据类。作为对象的函数：头等函数、相关设计模式和函数声明中的类型提示。面向对象的惯用法：组合、继承、mixin、接口、运算符重载、协议和更多静态类型。控制流：上下文管理器、生成器、协程、async／await和线程／进程池。元编程：属性、特性描述符、类装饰器以及替代或简化元类的新类元编程钩子。
