This is not a bug. The "is" operator works as expected. A method descriptor returns a new wrapper object on each access. CPython uses free lists to "recycle" memory locations to increase performance. id(Class.method.__get__(None, Class)) == id(Class.method) is true because the return value of "Class.method.__get__(None, Class)" is garbage collected and the memory address is reused. See: >>> class Class: ... def method(self): ... ... >>> instance = Class() >>> m1 = Class.method.__get__(instance, Class) >>> m2 = instance.method >>> id(m1) == id(m2) False ---------- nosy: +christian.heimes resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39997> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
