The Python Tutorial
######################
:Release: |version|
:Date: |today|
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.
Python 是一门简单易学的强大编程语言。它有高效的高级数据结构和简单有效的
面向对象编程方式。Python 的优雅语法和动态类型，以及它解释语言的特质，
使其在很多平台上都成为理想的脚本和快速应用开发语言。
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,
http://www.python.org/, 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.
Python 解释器及其扩展标准库的源码和编译版本可以从 Python 的 Web 站点
http://www.python.org/ 免费获得，并且可以自由分发。该站点还提供了很多
免费的第三方 Python 模块、程序和工具，及其附加文档。
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.
Python 解释器可以很容易的通过 C 或者 C++ （或其它可以通过 C 调用的语
言）扩展新的函数和数据类型。Python 也可以作为定制应用的扩展语言。
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.
本手册向读者介绍 Python 语言及其系统的基本知识与概念。配合 Python 解释
器学习会很有帮助，不过所有的例子都已经包括在文中，所以这本手册也可以离
线阅读。
For a description of standard objects and modules, see :ref:`library-index`.
:ref:`reference-index` gives a more formal definition of the language. To write
extensions in C or C++, read :ref:`extending-index` and
:ref:`c-api-index`. There are also several books covering Python in depth.
标准对象和模块的詳細介绍请参见 :ref:`library-index` 。
:ref:`reference-index` 提供了更多语言方面的说明。如编写 C 或 C++ 的
扩展，请阅读 :ref:`extending-index` 和 :ref:`c-api-index` 。这些文档深
入介绍了相关的 Python 知识。
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 :ref:`library-index`.
本手册不会涵盖 Python 的所有功能，也不会解释所用到的所有相关知识。相
反，它介绍了许多 Python 中最引人注目的功能，这会对读者掌握这门语言的风
格大有帮助。读过它后，你应该可以阅读和编写 Python 模块和程序，接下来可
以从 :ref:`library-index` 中进一步学习Python复杂多变的库和模块。
The :ref:`glossary` is also worth going through.
:ref:`glossary` 也值得一读。
