  Python 2.7入门指南(官方中文) 文档

Python入门指南Python是一门简单易学且功能强大的编程语言。它拥有高效的高级数据结构,并且能够用简单而又高效的方式进行面向对象编程。Python优雅的语法和动态类型,再结合它的解释性,使其在大多数平台的许多领域成为编写脚本或开发应用程序的理想语言。你可以自由的从Python官方点,,以源代码或二进制形式获取Python解释器及其标准扩展库,并可以自由的分发。此站点同时也提供了大量的第三方Python模块、程序和工具,及其附加文档。http://www.python.org你可以很容易的使用C或C++(其他可以通过C调用的语言)为Python解释器扩展新函数和数据类型。Python还可以被用作定制应用程式的一门扩展语言。本手册非正式的向读者介绍了Python语言及其体系相关的基本知识与概念。在学习实践中结合使用Python解释器是很有帮助的,不过所有的例子都是完整的,所以本手册亦可离线阅读。

  Python编码规范 文档

缺省情况下你的程序需要使用ascii码来写,但如果在其中写中文的话,python解释器一般会报错,但如果加上你所用的文件编码,python就会自动处理不再报错。 windows 下不需要这个路径, 可以直接双击执行, 但是依赖于可执行环境, 有的时候editplus 会将.py文件的默认打开程序由python修改为editplus, 需要自己手动设置回来,或者创建一个桌面快捷方式的时候,在配置文件中指定一下就可以了。

  将你的科学计算从Matlab迁移到Python? 文档

一切的一切起源于我看了一篇英文文章,说使用Python作科学计算有时比Matlab更加高效,还有那无数次见到的牛逼公式: ,看的我心潮澎湃,我就寻思了,反正最近在做的那个算法用Matlab跑实验跑得不是太理想,要不咱也迁移一把,由于今天比较蛋疼,就决定开始尝试了,经过蛋疼的一天,我得出了开头那个结论:如果你有现成的Matlab算法,还是Matlab吧,如果你像我一样蛋疼,那就迁移吧。不相信,那就听我把遇到的一堆乱七八糟的事情娓娓道来吧,其中夹杂着我的一些弱弱的解决方案

Python基础入门 文档

现在网上已经有不少学习python的课程,其中也不乏精品。按理说,不缺少我这个基础类型的课程了。但是,我注意到一个问题,不管是课程还是出版的书,大多数是面向已经有一定编程经验的人写的或者讲的,也就是对这些朋友来讲,python已经不是他们的第一门高级编程语言。据我所知,目前国内很多大学都是将之类的做为学生的第一门语言。然而,在我看来python是非常适合做为学习高级语言编程的第一门语言的。有一本书,名字叫《与孩子一起学编程》这本书的定位是将python定位为学习者学习的第一门高级编程语言。然而由于读者对象是孩子,很多“成年人”不屑一顾,当然,里面的讲法与“实战”有点距离导致以“找工作”、“工作需要”为目标的学习者认为这本书跟自己要学的方向相差甚远。为了弥补那本书的缺憾,我在这里推出面向成年人——大学生、或者其他想学习程序但是没有任何编程基础的朋友——学习第一门编程高级语言的教程。

Fluent Python 英文版 文档

Python s simplicity lets you become productive quickly, but this often means you aren t using everything it has to offer. With this hands-on guide, you ll learn how to write effective, idiomatic Python code by leveraging its best and possibly most neglected features. Author Luciano Ramalho takes you through Python s core language features and libraries, and shows you how to make your code shorter, faster, and more readable at the same time. Many experienced programmers try to bend Python to fit patterns they learned from other languages, and never discover Python features outside of their experience. With this book, those Python programmers will thoroughly learn how to become proficient in Python 3.

Starting Out with Python 文档

In Starting Out with Python , Second Edition Tony Gaddis’ evenly-paced, accessible coverage introduces students to the basics of programming and prepares them to transition into more complicated languages. Python, an easy-to-learn and increasingly popular object-oriented language, allows readers to become comfortable with the fundamentals of programming without the troublesome syntax that can be challenging for novices. With the knowledge acquired using Python, students gain confidence in their skills and learn to recognize the logic behind developing high-quality programs.<br> Starting Out with Python discusses control structures, functions, arrays, and pointers before objects and classes. As with all Gaddis texts, clear and easy-to-read code listings, concise and practical real-world examples, detail-oriented explanations, and an abundance of exercises appear in every chapter. This text is intended for a one-semester introductory programming course for students with limited programming experience.

Python v2.7.5 文档 文档

Numeric handling has been improved in many ways, for both floating-point numbers and for the Decimal class. There are some useful additions to the standard library, such as a greatly enhanced unittest module, the argparse module for parsing command-line options, convenient OrderedDict and Counter classes in the collections module, and many other improvements.<br> Python 2.7 is planned to be the last of the 2.x releases, so we worked on making it a good release for the long term. To help with porting to Python 3, several new features from the Python 3.x series have been included in 2.7.
