Python is an open source, scientific programming language offering all of the features of bigger, better known languages. Python has found uses everywhere from NASA, Industrial Lights and Magic, YouTube and countless others. Like other open source projects, it is well maintained and overseen by a leadership organization Python.org. Best of all, it is freely downloaded from a number of sources including Python.org and Enthought.com. If you do desktop scientific and engineering computing, this is well worth your time. In addition to the core language, many libraries are also available for every application from graphics to signal processing. This is truly a comprehensive scripting language.
