Python 2.7.8 学习笔记（001）python manuals/the python tutorial

Posted 2020-06-17

从今天开始学python， python有点意思，第一感觉界面和matlab有点像。

手头没有什么资料，就从安装好了的一个python 2.7.8，里面有个英文版的manual，那就只好从这里开始吧，为什么不是中文版的呢？？那就边看边翻译吧。

python漫游指南：python是一种简单易学功能强大的编程语言。它有高效的数据结构和简单但有效的面向对象编程方法。python优雅的语法和动态拼写以及解释特性，使得它在许多平台上成为一种理想的脚本语言和快速程序开发工具。

python的解释器和扩展标准库包括源码和二进制形式，可以从主要平台——python的网站http://www.python.org上下载，也可以自由传播。同样，网站也含有许多第三方python模块、程序、工具和文档。

python的解释器可以很容易地用C/C++来扩展新函数和数据类型。python也适合作为一种定制化程序的扩展语言。

本tutorial向读者非正式地介绍基本概念，python特性。。。

算了，从网上找到别人翻译的了，我还是把注意力放在python本身的学习上吧。
