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.
|
|
|
|
Release Derived Year Owner GPL-
|
|

2.3 2.2.2 2002-2003 PSF yes
|
|
|
|
Footnotes:
|
|
|
|
(1) GPL-compatible doesn't mean that we're distributing Python under
|
|
the GPL. All Python licenses, unlike the GPL, let you distribute
|
|
a modified version without making your changes open source. The
|
|
GPL-compatible licenses make it possible to combine Python with
|
|
other software that is released under the GPL; the others don't.
|
|
|
|
(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
|
|
because its license has a choice of law clause. According to
|
|
CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
|
|
is "not incompatible" with the GPL.
|
|
|
|
Thanks to the many outside volunteers who have worked under Guido's
|
|
direction to make these releases possible.
