Solve the following python programming problem given the following code:
def test_raises_expected_exception(self, sleep_mock) : 
    retry = retrying.Retry (max_attempts = 10, expected_exceptions = [KeyError]) 
    @ retry 
    def func() : 
        raise KeyError () 
self.assertRaises (KeyError, retry) 
    self.assertEqual (retry.attempt, 1) 
    self.assertFalse (sleep_mock.called)
