Python核心编程(第2版)

欢迎走进Python核心编程我们很高兴能帮你尽快并尽可能深入地学习Python。掌握语法是本书的一个目标,不管怎样,我们都坚信,哪怕是一个初学者,只要他能掌握Python的运作机理,他就不再仅仅是用Python“编写”,而是能开发出更高效的Python应用程序。但是你知道,并不是掌握了一门语言的语法就能让你立刻登堂入室。在本书中,你能发现许多可以立即上手的例子。为了巩固基础,你还会在每章的末尾找到有趣又富有挑战性的习题。这些初级和中级水平的习题可以检验你的学习效果,并且提升你的Python技巧。确实没有什么能代替经验,我们只是想尽量用最短的时间让你不止初涉Python,而且能学会驾驭它。关于本书本书之所以比其他Python书籍畅销,是因为它拥有广泛的选题、丰富的例子和必要的深入解析。本书不需要你拥有C语言或者面向对象程序设计之类的背景。本书同样也不是一本让你很难入门的个案解析。最后,本书也绝非一本纯粹的参考书或者快速入门指南。你手中的这本书包括了针对这门语言特性的包罗万象的介绍(第一部分中),通过其下各章你可以洞悉Python编程的每个细节。本书40%是介绍,40%是晋级,余下的20%则是参考。我们将目标锁定于那些已经熟悉某种其他高级语言的人士和大、中学生。因为Python可以应用于Zope、Plone、MailMan和Django等大型的解决方案,所以本书可能被主要用于与这些系统有关的开发、管理、维护和整合工作。

Praise for Core Python Programming

"The long-awaited second edition of Wesley Chun's Core Python Programming proves to be well worth the wait–its deep and broad coverage and useful exercises will help readers learn and practice good Python."

–Alex Martelli, author of Python in a Nutshell and editor of Python Cookbook

"There has been lot of good buzz around Wesley Chun's Core Python Programming. It turns out that all the buzz is well earned. I think this is the best book currently available for learning Python. I would recommend Chun's book over Learning Python (O'Reilly), Programming Python (O'Reilly), or The Quick Python Book (Manning)."

–David Mertz, Ph.D., IBM DeveloperWorks®

"I have been doing a lot of research [on] Python for the past year and have seen a number of positive reviews of your book. The sentiment expressed confirms the opinion that Core Python Programming is now considered the standard introductory text."

–Richard Ozaki, Lockheed Martin

"Finally, a book good enough to be both a textbook and a reference on the Python language now exists."

–Michael Baxter, Linux Journal

"Very well written. It is the clearest, friendliest book I have come across yet for explaining Python, and putting it in a wider context. It does not presume a large amount of other experience. It does go into some important Python topics carefully and in depth. Unlike too many beginner books, it never condescends or tortures the reader with childish hide-and-seek prose games. [It] sticks to gaining a solid grasp of Python syntax and structure."

–http://python.org bookstore Web site

"[If ] I could only own one Python book, it would be Core Python Programming by Wesley Chun. This book manages to cover more topics in more depth than Learning Python but includes it all in one book that also more than adequately covers the core language. [If] you are in the market for just one book about Python, I recommend this book. You will enjoy reading it, including its wry programmer's wit. More importantly, you will learn Python. Even more importantly, you will find it invaluable in helping you in your day-to-day Python programming life. Well done, Mr. Chun!"

–Ron Stephens, Python Learning Foundation

"I think the best language for beginners is Python, without a doubt. My favorite book is Core Python Programming."

–s003apr, MP3Car.com Forums

"Personally, I really like Python. It's simple to learn, completely intuitive, amazingly flexible, and pretty darned fast. Python has only just started to claim mindshare in the Windows world, but look for it to start gaining lots of support as people discover it. To learn Python, I'd start with Core Python Programming by Wesley Chun."

–Bill Boswell, MCSE, Microsoft Certified Professional Magazine Online

"If you learn well from books, I suggest Core Python Programming. It is by far the best I've found. I'm a Python newbie as well and in three months time I've been able to implement Python in projects at work (automating MSOffice, SQL DB stuff, etc.)."

–ptonman, Dev Shed Forums

"Python is simply a beautiful language. It's easy to learn, it's cross-platform, and it works. It has achieved many of the technical goals that Java strives for. A one-sentence description of Python would be: 'All other languages appear to have evolved over time--but Python was designed.' And it was designed well. Unfortunately, there aren't a large number of books for Python. The best one I've run across so far is Core Python Programming."

–Chris Timmons, C. R. Timmons Consulting

"If you like the Prentice Hall Core series, another good full-blown treatment to consider would be Core Python Programming. It addresses in elaborate concrete detail many practical topics that get little, if any, coverage in other books."

–Mitchell L Model, MLM Consulting

"Core Python Programming is an amazingly easy read! The liberal use of examples helps clarify some of the more subtle points of the language. And the comparisons to languages with which I'm already familiar (C/C++/Java) get you programming in record speed."

–Michael Santos, Ph.D., Green Hills Software

"Python is an Internet and systems programming language that is soaring in popularity in today's fast-paced software development environment, and no wonder: it's simple (yet robust), object-oriented (yet can be used as a procedural language), extensible, scalable and features an easy to learn syntax that is clear and concise. Python combines the power of a compiled object language like Java and C++ with the ease of use and rapid development time of a scripting language. In fact, it's syntax is so easy to understand that you are more likely to pick it up faster than any of the other popular scripting languages in use today! In Core Python Programming, Internet software engineer and technical trainer Wesley Chun provides intermediate and experienced developers all they need to know to learn Python-fast. Like all Core Series books, Core Python Programming delivers hundreds of industrial-strength code snippets and examples, all targeted at professional developers who want to leverage their existing skills! In particular, Core Python Programming presents numerous interactive examples that can be entered into the Python interpreter right in front of you! Finally, we present a chapter that shows you step-by-step how to extend Python using C or C++."--Back cover [soweinc].5 .Python2()([]Chun,W.J.)Core PYTHON Programming: :::1:16:2008-07-01::654:::|
