sip -- SIP - Python/C++ Bindings Generator
http://www.riverbankcomputing.co.uk/
SIP is a tool for generating bindings for C++ classes so that they can be accessed as normal Python classes. SIP takes many of its ideas from SWIG but, because it is specifically designed for C++ and Python, is able to generate tighter bindings. SIP is so called because it is a small SWIG. SIP was originally designed to generate Python bindings for KDE and so has explicit support for the signal slot mechanism used by the Qt/KDE class libraries. However, SIP can be used to generate Python bindings for any C++ class library.
