Steven D'Aprano <steve+pyt...@pearwood.info> added the comment:
The ``is`` operator returns False because the two objects are different objects. Methods are descriptors, and whenever you access an instance method, you get a brand-new method object. This is described in the documentation for descriptors: https://docs.python.org/3/howto/descriptor.html#functions-and-methods The last two tests in your example both call id(a.a), which returns the same ID number for precisely the same reason as we explained in your previous bug report #36156. Since the two "a.a" method objects don't exist at the same time, the interpreter is permitted to re-use the same ID number for them. P.S. remember in the previous bug report you raised, I asked you to use less awkward and confusing names? "a.a" is a terrible name, even for a simple example like this. It makes it hard to talk about what is going on when "a" is an instance and also a method. ---------- nosy: +steven.daprano resolution: -> not a bug stage: -> resolved status: open -> closed _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36163> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
