Python库参考手册中文版

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 inaccessible 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.

(which may or may not be available, depending on whether the underlying platform supports them and on the

configuration choices made at compile time). It also documents the standard types of the language and its built-in

functions and exceptions, many of which are not or incompletely documented in the Reference Manual.

本参考手册罗列并说明了Python 标准库的各种功能, 以及许多非核心的模组(按不同的操作系统和编译时

的设置而定, 不是每台机上的Python 都能用这些模组.) 本手册同时记载了Python 语言所有的标准数据类

型, 内建函数, 异常类, 这些在参考手册中被忽略了或只是扼要的提过一下.

This manual assumes basic knowledge about the Python language. For an informal introduction to Python, see the

Python Tutorial; the Python Reference Manual remains the highest authority on syntactic and semantic questions.

Finally, the manual entitled Extending and Embedding the Python Interpreter describes how to add new extensions

to Python and how to embed it in other applications.
