One of the features of Python that makes it so powerful is the ability to take existing libraries, written in C or C++, and make them available as Python extension modules. Such extension modules are often called bindings for the library. SIP is a tool that makes it very easy to create Python bindings for C and C++libraries. It was originally developed to create PyQt, the Python bindings for the Qt toolkit, but can be used to create bindings for any C or C++library. SIP comprises a code generator and a Python module. The code generator processes a set of specification files and generates C or C++code which is then compiled to create the bindings extension module. The Python module provides support functions to the automatically generated code. Normally a package containing SIP generated bindings includes a private copy of the Python module. The specification files contain a description of the interface of the C or C++library, i.e. the classes, methods, functions and variables. The format of a specification file is almost identical to a C or C++header file, so much so that the easiest way of creating a specification file is to edit the corresponding header file. SIP makes it easy to exploit existing C or C++libraries in a productive interpretive programming environment. SIP also makes it easy to take a Python application (maybe a prototype) and selectively implement parts of the application (maybe for performance reasons) in C or C++.
