内容简介
  Python是一种理想的独立程序和脚本程序语言,具有可移植、强大和易用的特点。无论您是初学程序设计还是初学Python,都能通过本书快速而高效地掌握Python核心语言的基础。通读本书,您可以获得足够多的知识,能够学习将Python用于您所选择的任何应用领域。《学习Python(第三版)》基于作者Mark Lutz在过去10年间讲授培训课程所使用的资料。除了大量的注解插图和每章总结外,作者还为每章加入了独特的一节,通过实际练习和复习提问的方式,让您在学习过程中练习新的技能,测验对概念的理解程度。本书内容包括:类型和运算——深入Python内置对象类型:数值、列表、字典及其他。语句和语法——用来创建和处理对象的Python代码以及Python通用语法模型。函数——Python的基本结构化和代码重用工具。模块——将语句、函数和其他工具组织为更大的组件。类和面向对象编程——可选的Python面向对象程序设计工具,用于定制和重用结构化代码。异常和工具——处理语句和模块异常,并介绍编写较大型程序所使用的开发工具。有关即将发布的Python 3.0的一些讨论。《学习Python 第三版》为您理解Python语言提供了完整而又深入的介绍,帮助您领会在以后的工作中会遇到的应用级Python实例。如果您准备好探索Google和YouTube究竟从Python中发现了什么,那么本书就是一个最好的开始。
