I've discovered something slightly misleading in the docs for PyObject_IsInstance:
When testing if B is a subclass of A, if A is B, PyObject_IsSubclass returns true. If A and B are different objects, B‘s __bases__ attribute is searched... This suggests that issubclass(A, A) will always be true, regardless of what attributes A has. However, this turns out not to be so -- A must also have a __bases__ attribute, otherwise it's rejected as not being sufficiently class-like. -- Greg _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
