卢茨（Lutz，M），作为Python培训界的领军人物，Mark Lutz是有关Python方面的最早和最畅销书籍的作者，并且从1992年起就是Python社区的先驱之一。同时他还是O'Reilly的《Programming Python》和《Python Pocket Reference》两本书的作者。Mark从1997年开始教授Python课程，截至2007年已经指导了超过200次培训。此外Mark拥有计算机科学学士和硕士学位，以及25年的软件开发经验。
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。
