学习编程语言，很多弯路可走，有一条路可能不是捷径但一定不是弯路，那就是官方文档的阅读与消化！
Python is an easy to learn, powerful programming language. It has efficient high-level data structures and a simple but effective approach to object-oriented programming. Python’s elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.
自译：Python是一门功能强大并且易于学习的程序语言。它拥有高效率的数据结构，是一门简单但高效的面向对象程序语言，Python优雅简洁的语法和动态的特性，结合它的易读性，使它成为了在大多数平台上诸多领域的脚本编写和快速程序开发的理想编程语言。
The Python interpreter and the extensive standard library are freely available in source or binary form for all major platforms from the Python Web site, /, and may be freely distributed. The same site also contains distributions of and pointers to many free third party Python modules, programs and tools, and additional documentation.
自译：Python的解释器和扩展丰富的标准库可以以源代码或二进制格式的从Python网站免费获得，站点上也包含了很多免费的第三方Python模块，程序、工具以及其他文档。
The Python interpreter is easily extended with new functions and data types implemented in C or C++ (or other languages callable from C). Python is also suitable as an extension language for customizable applications.
自译：Python 的解释器是非常容易用C或C++辩称语言(或者其他调用C语言的编程语言)扩展出新的功能或数据类型的。Python也非常适合作为定制程序的扩展语言。
This tutorial introduces the reader informally to the basic concepts and features of the Python language and system. It helps to have a Python interpreter handy for hands-on experience, but all examples are self-contained, so the tutorial can be read off-line as well.
自译：本教程会为读者以非正式的方式介绍基础的概念、python语言和系统的特征。自带了Python解释器以亲手操作，但所有的例子都是自己包含的，所以本教程也可以离线使用。
For a description of standard objects and modules, see The Python Standard Library. The Python Language Reference gives a more formal definition of the language. To write extensions in C or C++, read Extending and Embedding the Python Interpreter and Python/C API Reference Manual. There are also several books covering Python in depth.
自译：对于标准对象和模块的描述，请参见Python标准库。Python语言指引给了很多编程语言官方的定义。如果为了使用C或C++进行扩展应用的构建，请阅读Python解释器和Python/C的API的扩展和嵌入的参考手册。有很多深入讲解Python的书籍。
This tutorial does not attempt to be comprehensive and cover every single feature, or even every commonly used feature. Instead, it introduces many of Python’s most noteworthy features, and will give you a good idea of the language’s flavor and style. After reading it, you will be able to read and write Python modules and programs, and you will be ready to learn more about the various Python library modules described in The Python Standard Library.
自译：本教程并未试图讲解多么复杂、涵盖每一个偏的功能或者包含每一个常用的功能，相反的是教程介绍了很多Python值得注意的功能，并且会帮助你更好了解Python编程语言的模块和程序，如果想学习更多python的库模块，请去Python标准库进行了解和学习。
