# Extending and Embedding the Python Interpreter

This document describes how to write modules in C or C++ to extend the Python interpreter with new modules. Those modules can not only define new functions but also new object types and their methods. The document also describes how to embed the Python interpreter in another application, for use as an extension language. Finally, it shows how to compile and link extension modules so that they can be loaded dynamically (at run time) into the interpreter, if the underlying operating system supports this feature.

This document assumes basic knowledge about Python. For an informal introduction to the language, see Python 教學. The Python Language Reference gives a more formal definition of the language. Python 標準函式庫 (Standard Library) 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 參考手冊.

備註

This guide only covers the basic tools for creating extensions provided as part of this version of CPython. Third party tools may offer simpler alternatives. Refer to the binary extensions section in the Python Packaging User Guide for more information.
