1. A simple, high-level interpreted language invented by Guido van Rossum in 1991. Python combines ideas from ABC, C, Modula-3 and Icon. It bridges the gap between C and shell programming, making it suitable for rapid prototyping or as an extension language for C applications. It is object-oriented and supports packages, modules, classes, user-defined exceptions, a good C interface, dynamic loading of C modules and has no arbitrary restrictions. Python is available for many platforms, including Unix, Windows, DOS, OS/2, Macintosh and Amoeba. Latest version: 2.5, as of 2007-02-21. (http://python.org/). Usenet newsgroup: news:comp.lang.python.
