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 :ref:`tutorial-index`. :ref:`reference-index`
|
|
gives a more formal definition of the language. :ref:`library-index` 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
|
|
:ref:`c-api-index`.

Recommended third party tools
|
|
=============================
|
|
|
|
This guide only covers the basic tools for creating extensions provided
|
|
as part of this version of CPython. Third party tools like Cython,
|
|
``cffi``, SWIG and Numba offer both simpler and more sophisticated
|
|
approaches to creating C and C++ extensions for Python.

`Python Packaging User Guide: Binary Extensions <https://packaging.python.org/en/latest/extensions.html>`_
|
|
The Python Packaging User Guide not only covers several available
|
|
tools that simplify the creation of binary extensions, but also
|
|
discusses the various reasons why creating an extension module may be
|
|
desirable in the first place.
|
|
|
|
|
|
Creating extensions without third party tools
|
|
=============================================
|
|
|
|
This section of the guide covers creating C and C++ extensions without
|
|
assistance from third party tools. It is intended primarily for creators
|
|
of those tools, rather than being a recommended way to create your own
|
|
C extensions.

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.
