Dave Malcolm <dmalc...@redhat.com> added the comment: >From IRC discussion, how about something like:
The current implementation consolidates integers in the range -5 to 256 (inclusive) into singleton PyIntObject instances, whereas other integer values have unique PyIntObject instances created for them. This means that on CPython:: >>> -5 is -5 True but:: >>> -6 is not -6 False This behavior is an implementation detail of CPython, and is not required by other implementations of Python. In particular: - do not manipulate the internal value of a PyIntObject after creation - do not use "is" for comparing integer values, use "==" instead. ---------- nosy: +dmalcolm _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11846> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
