★ 只需编程基础 ★ 从零开始自制编程语言 ★ 支持面向对象、异常处理等高级机制 本书手把手地教读者用C语言制作两种编程语言：crowbar与Diksam。crowbar是运行分析树的无类型语言，Diksam是运行字节码的静态类型语言。这两种语言都具备四则运算、变量、条件分支、循环、函数定义、垃圾回收等功能，最终版则可以支持面向对象、异常处理等高级机制。所有源代码都提供下载，读者可以一边对照书中的说明一边调试源代码。这个过程对理解程序的运行机制十分有帮助。 本书适合有一定基础的程序员和编程语言爱好者阅读。

Python是当今世界流行的编程语言之一。本书共15章，通过一些短小精悍的交互式Python脚本帮助学生进行练习，并在这个过程中掌握诸如数据结构、排序和搜索算法、面向对象编程、数据库访问、图形用户界面等基本概念以及良好的程序设计风格。本书既是一本注重科学的计算机科学专业教材，也是一本目标明确的Python参考书。 本书语言风格言简意赅，图表丰富，简单实用，是一本优秀的Python入门级读物，适合Python初学者使用。

The purpose of this book is to help you understand how to program shared-memory parallel machines without risking your sanity.1 By describing the algorithms and designs that have worked well in the past, we hope to help you avoid at least some of the pitfalls that have beset parallel projects. But you should think of this book as a foundation on which to build, rather than as a completed cathedral. Your mission, if you choose to accept, is to help make further progress in the exciting field of parallel programming, progress that should in time render this book obsolete. Parallel programming is not as hard as it is reputed, and it is hoped that this book makes it even easier for you.
