It looks like the error is in inspect.formatannotation(). For instances of type, that function incorrectly returns only annotation.__qualname__. Instead, it should return repr(annotation) which would include the args. ================================================================= def formatannotation(annotation, base_module=None): if getattr(annotation, '__module__', None) == 'typing': return repr(annotation).replace('typing.', '') if isinstance(annotation, type): # <== Erroneous case if annotation.__module__ in ('builtins', base_module): return annotation.__qualname__ return annotation.__module__+'.'+annotation.__qualname__ return repr(annotation) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45438> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
