I have a class which inherits from one in the standard library of Python 2.7.6.
I would like to meet the conditions of the license of that code, which is the PSF LICENSE AGREEMENT FOR PYTHON 2.7.6 which (in part) says
... PSF hereby grants Licensee a ... license to ... use Python 2.7.6 alone or in any derivative version, provided, however, that PSF’s License Agreement and PSF’s notice of copyright, i.e., “Copyright © 2001-2014 Python Software Foundation; All Rights Reserved” are retained in Python 2.7.6 alone or in any derivative version prepared by Licensee
I'm wondering about the meaning of the second
or in that text, which suggests that I do not need to mention that copyright claim anywhere in my own code. It is sufficient not to remove the claim from Python 2.7.6 itself.
So, if I comply with the other clauses (especially clause 3, explaining my changes), then I am fully compliant and have no obligation to distribute any part of Python (in particular the license, or copyright claim) with my own code.
Does that seem a reasonable interpretation?
