A. HISTORY OF THE SOFTWARE

==========================

 

Python was created in the early 1990s by Guido van Rossum at Stichting

Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands

as a successor of a language called ABC.  Guido remains Python's

principal author, although it includes many contributions from others.

 

In 1995, Guido continued his work on Python at the Corporation for

National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)

in Reston, Virginia where he released several versions of the

software.

 

In May 2000, Guido and the Python core development team moved to

BeOpen.com to form the BeOpen PythonLabs team.  In October of the same

year, the PythonLabs team moved to Digital Creations (now Zope

Corporation, see http://www.zope.com).  In 2001, the Python Software

Foundation (PSF, see http://www.python.org/psf/) was formed, a

non-profit organization created specifically to own Python-related

Intellectual Property.  Zope Corporation is a sponsoring member of

the PSF.

 

All Python releases are Open Source (see http://www.opensource.org for

the Open Source Definition).  Historically, most, but not all, Python

releases have also been GPL-compatible; the table below summarizes

the various releases.
