I'm trying to fix@unittest.expectedFailuretest_inplace_on_self in filetest_set.py.
def test_inplace_on_self(self): t = self.s.copy() t |= t self.assertEqual(t, self.s) t &= t self.assertEqual(t, self.s). -> FAIL t -= t self.assertEqual(t, self.thetype()). -> FAIL t = self.s.copy() t ^= t self.assertEqual(t, self.thetype())I found the two operator fail.&= and-= is not work correctly.
[&= ]
