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.
