Extending Python Without Python’s C API
You can code Python extensions in other classic compiled languages besides C. For Fortran, the choice is between Paul Dubois’s Pyfort (available at http://pyfortran.sf.net) and Pearu Peterson’s F2PY (available at http://cens.ioc.ee/projects/f2py2e/). Both packages support and require the Numeric package covered in The Numeric Package, since numeric processing is Fortran’s typical application area.
For C++, you have many choices. SCXX (available at http://davidf.sjsoft.com/mirrors/mcmillan-inc/scxx.html) is a simple, lightweight package that uses no templates and is thus suitable for older C++ compilers. PyCXX (available at http://cxx.sf.net) uses a modest amount of templates, essentially ones from the C++ standard library. SIP (available at http://www.riverbankcomputing.co.uk/sip/index.php) also supports the C++ extensions needed to use the powerful Qt cross-platform libraries, but, while it fully supports Qt, it does not require it. The Boost Python Library (available at http://www.boost.org/libs/python/doc) is part of Boost, a vast treasury of powerful, template-rich C++ libraries, of uniformly high quality, that need and support modern C++ compilers that support templates very well.
Of course, you may also choose to use Python’s C API from your C++ code, using C++ in this respect as if it were C, and foregoing the extra convenience that C++ affords. However, if you’re already using C++ rather than C anyway, then using SCXX, PyCXX, SIP, or ...
