Integrating Python with Other Languages¶

Legacy Wiki Page

This page was migrated from the old MoinMoin-based wiki. Information may be outdated or no longer applicable. For current documentation, see python.org.

[Hint: The idea is to create pages for the stuff, not just link it.]

C/C++¶

There a various tools which make it easier to bridge the gap between Python and C/C++:

Pyrex - write your extension module on Python 💡
Cython – Cython – an improved version of Pyrex
CXX - PyCXX - helper lib for writing Python extensions in C++
ctypes is a Python module allowing to create and manipulate C data types in Python. These can then be passed to C-functions loaded from dynamic link libraries.
elmer - compile and run python code from C, as if it was written in C
PicklingTools is a collection of libraries for exchanging Python Dictionaries between C++ and Python.
weave - include C code lines in Python program (deprecated in favor of Cython)
ackward exposes parts of Python’s standard library as idiomatic C++
CFFI - interact with almost any C code from Python, based on C-like declarations that you can often copy-paste from header files or documentation.

0.1. C/C++ Binding Generators¶

Tools to make C/C++ functions/methods accessible from Python by generating binding (Python extension or module) from header files.

boost.python - Expose C++ classes functions and objects to Python, and vice-versa, using just C++ compiler
PyAutoC - Automatically wrap C functions and structs, using just C compiler.
pwig is a SWIG extension for writing new language modules in Python.
PyBindGen Python bindings code generator for pure C or C++ APIs. The generator is written in Python and has low complexity. The generated code is lean, efficient, and highly readable
shiboken - Binding Generator used to create PySide Python bindings for Qt
SIP - similar to SWIG but specialised for Python and C++. Used to create PyQt, the Qt API wrapper library
SWIG - generate extension module from your .h files
pybind11 - Similar to Boost.Python, but with a lean header-only implementation for C++11-capable compilers.
pyclif - Google tool. Similar to SWIG, but user-friendly and targeted only C++11 well-written libs.
cppyy - Fast, automatic, Python-C++ bindings, including run-time template instantiations, cross-inheritance, auto-casting, etc.
Scapix Language Bridge - generates Python (and other languages) bindings directly from C++ headers.
