Python is an extensible, interpreted, object-oriented programming language. It supports a wide range of applica-
tions, from simple text processing scripts to interactive Web browsers.
Python 是一种可扩展的, 即译式, 面向对象规格的编程语言. 它能应用在极广泛的地方, 从简单的文字处理
工作到交互式的网页浏览器.
While the Python Reference Manual describes the exact syntax and semantics of the language, it does not describe
the standard library that is distributed with the language, and which greatly enhances its immediate usability.
This library contains built-in modules (written in C) that provide access to system functionality such as file I/O
that would otherwise be essible to Python programmers, as well as modules written in Python that provide
standardized solutions for many problems that occur in everyday programming. Some of these modules are
explicitly designed to encourage and enhance the portability of Python programs.
Python 语言参考手册中精确地描述了Python 语言的句法及语义. 然而语言参考手册中没有提到Python 所
附带功能强大的标准库. 这个函式库大大地增强了Python 的实用性. 其中包括C 写的内建模组, 提供介面
让程式进行操作系统层次的工作, 例如档案的输出输入; 同时也有以Python 语言本身编写的模组, 为实际
编程时常遇的问题提供标准解决方案. 这类模组有的经过特别设计以便Python 程式在跨平台的情况下运
行无误.
This library reference manual documents Python’s standard library, as well as many optional library modules
(which may or may not be available, depending on whether the underlying platform supports them and on the
configuration choices made pile time). It also documents the standard types of the language
