New submission from Mark Dickinson <dicki...@gmail.com>: Currently in py3k, order comparisons for complex numbers raise a TypeError. This was necessary in Python 2.x in order to make a complex <-> complex comparison raise an exception. In 3.x, it's no longer necessary, since if both sides of a comparison return NotImplemented the result of the comparison is a TypeError (in 2.x the result is a value based on comparing the ids).
In py3k, complex.__lt__ could be changed to always return NotImplemented. This would allow a custom class to implement its own comparisons with complex, and would remove an unnecessary special case. ---------- assignee: mark.dickinson components: Interpreter Core messages: 98783 nosy: mark.dickinson priority: normal severity: normal status: open title: complex.__lt__ should return NotImplemented instead of raising TypeError type: behavior versions: Python 3.2 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7845> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
