内容简介

　　《Python3面向对象编程（第2版 影印版 英文版）》讲解了类、数据封装、继承、多态、抽象和异常，着重强调了在一款设计良好的软件开发过程中使用每个原则的时机。除了学习如何利用高层次的设计模式来创建可维护的应用程序，你还可以了解到字符串和文件处理的复杂性以及Python区分二进制数据和文本数据的方法。另外，单元测试的乐趣以及并发编程的难题也是少不了的。
　　书中更新了大量的内容，以反映出近来核心Python库的变化，这些新的特性在《Python3面向对象编程（第2版 影印版 英文版）》备受赞誉的第1版面世时还无法使用。除此之外，全书的结构也进行了重新调整和组织，提升了知识量，增强了阅读体验。
　　目标读者如果你是初次接触面向对象编程技术，或是只具备基本的Python技能，希望能够深入学习如何正确地使用Python面向对象编程技术来设计软件，那么《Python3面向对象编程（第2版 影印版 英文版）》就是为你准备的。
　　你将从《Python3面向对象编程（第2版 影印版 英文版）》中学到什么通过创建类和定义方法来实现Python对象。
　　将相关的对象划分成不同的类，通过类接口来描述这些对象的属性和行为。
　　使用继承来扩展类的功能。
　　明白什么时候使用面向对象特性，什么时候不使用（后者更重要）。
　　了解什么是设计模式，为什么在Python中有这些不同的设计模式。
　　揭示单元测试的简洁性及其在Python中的重要性。
　　理解Python3中常见的并发编程技术和陷阱。
　　探究用于开发大规模并发网络系统的新模块Async10。
