The Python Tutorial
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 是易学的、拥有高效的高层次数据结构的、面向对象的、动态类型的、解释性的编程语言。
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, https://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.
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 的解释器易于扩展，并且其数据类型用 C/Cpp 实现。Python 也适合作为其它客制化应用的扩展语言。
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.
这篇教程给予读者以 Python 语言及其生态的基础语法和特点，并且所有的用例都是离线可用的，只要手头有一个 Python 解释器。
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.

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.
这篇教程不是让读者深入理解 Python，也没有覆盖每一个特点，而是介绍 Python 最值得注意的特点。读者读完之后，应当能够编写简单的 Python 程序和模块，也能深入理解 Python 标准库。
The Glossary is also worth going through.
