New submission from Craig Coleman <craig.s.r.cole...@gmail.com>:
In a test, dataclasses generate an __eq__ function appears to be wrong. @dataclass class C: pass class K: pass a = C() b = C() c = K() d = K() (a is b) # False (a == b) # True # Incorrect, Why? (c is d) # False (c == d) # False # Correct Using @dataclass(eq = False) for annotation of C would make (a == b) == False which I think is correct behaviour. ---------- components: Library (Lib) messages: 413188 nosy: ccoleman priority: normal severity: normal status: open title: dataclasses __eq__ isn't logical type: behavior versions: Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46739> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
