The Python Language Home Page is hosted by the Corporation for National Research Initiatives (CNRI), Reston, VA. Python is an "interpreted, interactive, object-oriented, extensible programming language." It is both clear and versatile, freely available, and it runs on Unix, PC, and many other systems. Python was developed in the early 1990s at CWI in Amsterdam (the Netherlands); it has seen continuing development and widespread use since then. The site contains the official Python source code distribution, binaries, documentation, and conference proceedings. It also hosts a collection of contributed code and contains links to organizations and mailing lists that provide technical support for Python users. There are links to various projects that are using Python as well as to a number of special interest group (SIG) mailing lists. The SIGs are working to extend and enhance Python.
