扩展和嵌入 Python 解释器

本文档描述了如何使用 C 或 C++ 编写模块以使用新模块来扩展 Python 解释器的功能。 这些模块不仅可以定义新的函数,还可以定义新的对象类型及其方法。 该文档还描述了如何将 Python 解释器嵌入到另一个应用程序中,以用作扩展语言。 最后,它展示了如何编译和链接扩展模块,以便它们可以动态地(在运行时)加载到解释器中,如果底层操作系统支持此特性的话。

This document assumes basic knowledge about Python. For an informal introduction to the language, see Python 教程. Python 语言参考 gives a more formal definition of the language. Python 标准库 documents the existing object types, functions and modules (both built-in and written in Python) that give the language its wide application range.

For a detailed description of the whole Python/C API, see the separate Python/C API 参考手册.

Embedding the CPython runtime in a larger application

Sometimes, rather than creating an extension that runs inside the Python interpreter as the main application, it is desirable to instead embed the CPython runtime inside a larger application. This section covers some of the details involved in doing that successfully.
