The Python License is a deprecated permissive computer software license created by the Corporation for National Research Initiatives (CNRI).
It was used for versions 1.6 and 2.0 of the Python programming language, both released in the year 2000.
[3] Python was created by Guido van Rossum and the initial copyright was held by his employer, the Centrum Wiskunde & Informatica (CWI).
During this time Python was distributed under a GPL-compatible variant of the Historical Permission Notice and Disclaimer license.
[4] CNRI obtained ownership of Python when Van Rossum became employed there, and after some years they drafted a new license for the language.
