Thanks for the bug report, Landon! I think I can reproduce this with a slightly shorter code snippet, but I don't think this is a bug: ``` >>> from dataclasses import dataclass, field >>> @dataclass ... class Character: ... sort_index: int = field(init=False, repr=False) ... intelligence: int ... def __post_init__(self): ... self.sortindex = self.intelligence ... >>> c = Character(intelligence=50) >>> c Character(intelligence=50) >>> c.sortindex 50 >>> c.sort_index AttributeError: 'Character' object has no attribute 'sort_index'. Did you mean: 'sortindex'? ``` This seems like the correct error message to me. The issue is that your "Character" class has a field named "sort_index", but that field is never assigned to. Instead, you assign an attribute named "sortindex" in your __post_init__ method. So the error message is correct: an instance of your Character class has no attribute "sort_index" (it only has a field named "sort_index"), but it *does* have an attribute "sortindex". ---------- nosy: +AlexWaygood, eric.smith status: open -> pending title: Dataclass Suggestion reversed: sortindex / sort_index -> Confusing error message for AttributeError with dataclasses _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46134> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
