Python makes an excellent glue language to connect software components. The CPython interpreter can easily be extended to provide new ways to manipulate and combine your programs and libraries. The core of the talk will be on how to develop extension modules for CPython using its C API. The presentation will also give insights how to write Python code which makes efficient use of the CPython interpreter. Please note that the audience will be expected to have a basic understanding of the C language. However, people who do not know C will probably still enjoy the commentaries about the design of the CPython interpreter and the overview of the alternative techniques available for extending it. Alexandre Vassalotti is a contributing Python core developer and a computer science student at McGill University. He was a successful participant of Google Summer of Code 2007, for which he worked on the different aspects of Python 3.0. Less
