\section{History of the software}
|
|
|
|
Python was created in the early 1990s by Guido van Rossum at Stichting
|
|
Mathematisch Centrum (CWI, see \url{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 \url{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 \url{http://www.zope.com/}). In 2001, the Python
|
|
Software Foundation (PSF, see \url{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
|
|
\url{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.
|
|
|
|
\begin{tablev}{c|c|c|c|c}{textrm}{Release}{Derived from}{Year}{Owner}{GPL compatible?}
|
|
\linev{0.9.0 thru 1.2}{n/a}{1991-1995}{CWI}{yes}
|
|
\linev{1.3 thru 1.5.2}{1.2}{1995-1999}{CNRI}{yes}
|
|
\linev{1.6}{1.5.2}{2000}{CNRI}{no}
|
|
\linev{2.0}{1.6}{2000}{BeOpen.com}{no}
|
|
\linev{1.6.1}{1.6}{2001}{CNRI}{no}
|
|
\linev{2.1}{2.0+1.6.1}{2001}{PSF}{no}
|
|
\linev{2.0.1}{2.0+1.6.1}{2001}{PSF}{yes}
|
|
\linev{2.1.1}{2.1+2.0.1}{2001}{PSF}{yes}
|
|
\linev{2.2}{2.1.1}{2001}{PSF}{yes}
|
|
\linev{2.1.2}{2.1.1}{2002}{PSF}{yes}
|
|
\linev{2.1.3}{2.1.2}{2002}{PSF}{yes}
|
|
\linev{2.2.1}{2.2}{2002}{PSF}{yes}
|
|
\end{tablev}
|
|
|
|
\note{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.}
|
|
|
|
Thanks to the many outside volunteers who have worked under Guido's
|
|
direction to make these releases possible.
