Python is typically used for non-graphic applications. It doesn't have a native graphics library, but graphics applications may be created by using graphics toolkits, some of which are cross-platform. Python is the product of a community effort, rather than a corporate project. Python was originated by the benevolent dictator Guido van Rossum. The language is characterized by a small syntax and huge variety of modules which extend the possibilities of the language. More information is available at http://www.python.org
