| According to the c code in Include/descrobject.h #define PyDescr_IsData(d) (Py_TYPE(d)->tp_descr_set != NULL) and according to the "data model" chapter, a data descriptor is an object who has __set__ and /or __delete__. the "inspect.isdatadescriptor" checks for existence of __get__ and __set__ which IMHO is wrong. an object with __set__/__delete__ only will return falsely False (should be True). This is related to @Serhiy Storchaka comment in issue 26103 opened by @Aaron Hall. | ||
