What's happening is that typing.NamedTuple ignores non-annotated attributes entirely when computing the names it passes along to namedtuple(), so here "a" is just a class attribute. You're accessing it from there, but the tuple itself is entirely empty. Perhaps it should error out if no names at all are found? ---------- nosy: +Spencer Brown _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45972> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
