The second argument to assertRaises must be a function that assertRaises will call. assertRaises can't catch the error above because it is raised when the argument is evaluated, before assertRaises has even been called. This would work: self.assertRaises(TypeError, lambda: self.testListNone[:1]) Cheers, Ian
