define Package/python/Default/description
 Python is a dynamic object-oriented programming language that can be used
 for many kinds of software development. It offers strong support for
 integration with other languages and tools, comes with extensive standard
 libraries, and can be learned in a few days. Many Python programmers
 report substantial productivity gains and feel the language encourages
 the development of higher quality, more maintainable code.
