History

Python was created in late 1989 by Guido van Rossum at the National Research Institute for Mathematics and Computer Science in the Netherlands (CWI, see www.cwi.nl) as a successor of a language called ABC. The first version was released in February 1991. Guido remains Python's principal author, although it includes many contributions from others.

In 2001, the Python Software Foundation (PSF, see www.python.org/psf/) was formed, a non-profit organization created specifically to own Python-related Intellectual Property.
