Python is an interpreted, object-oriented programming language that runs on several operating systems, including Unix, Windows, OS/2 and Macintosh. The language is relatively easy to learn, and can be used for developing apps, or for more mundane tasks such as system administration, code generation and graphical user interfaces. Python was created by Guido van Rossum, whose favorite comedy group was, you guessed it, Monty Python's Flying Circus. Python is copyrighted, but the source code is freely available and can be commercially re-sold.
