=======================
Python was created in the early 1990s by Guido van Rossum at Stichting
Mathematisch Centrum (CWI, see https://www.cwi.nl/) in the Netherlands as a
Mathematisch Centrum (CWI, see https://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 https://www.cnri.reston.va.us/) in Reston,
Research Initiatives (CNRI, see https://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
https://www.zope.org/). In 2001, the Python Software Foundation (PSF, see
team moved to Digital Creations, which became
Zope Corporation. In 2001, the Python Software Foundation (PSF, see

(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.
