Abstract Python is an easy to learn, powerful programming language. It has ef?cient 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 是一种容易学习的强大语言。它包括了高效的高级数据结构，提供了一个简单但很有效的方式进行面向对 象编程。Python 优雅的语法，动态类型，以及它天然的解释能力，使其成为了大多数平台上应用于各领域 理想的脚本语言以及开发环境。 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 can be freely distributed. The same site also contains distributions of and pointers to many free third party Python modules, programs and tools, and additional documenta- tion. 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, /, 及其所有 镜像站上免费获得，并且可以自由发布。该站点上也提供了Python 的一些第三方模块，程序，工具，以及 附加的文档。 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 的解释器很容易通过C 或C++ （或者其它可以由C来调用的语言）来扩展新的函数和数据结构。因 此Python 也很适于作为定制应用的一种扩展语言。 This tutorial introduces the reader informally to the basic concepts and features of the Python
