I wouldn't dispute that. I have no experience with Jython/IronPython to confirm what they do. Also, this ordering for None is unmentioned in PEP 207: http://www.python.org/dev/peps/pep-0207 Nor is it tested in test_richcmp.py. That said, in CPython the ordering hasn't changed since rich comparisons were added in 2.1a (circa 2001): http://hg.python.org/cpython/file/b60831eeab5a/Objects/object.c#l514 Without this exception, comparing to None would use the type name (currently "NoneType", but "None" in v2.1), which I realize is also unspecified in the docs. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
