Solve the following python programming problem given the following code:
@ async_test 
def testUpdate(self) : 
    def _VerifyUpdate(updates, get_attrs, new_attrs, rv, rvs) : 
        update_res = self._client.UpdateItem (table = 'LocalTest2', key = DBKey (hash_key = 1, range_key = None), callback = None, attributes = updates, return_values = rv) 
        for (k, v) in rvs.items () : 
            self.assertEqual (update_res.return_values [k], v) 
get_res = self._client.GetItem (table = 'LocalTest2', key = DBKey (hash_key = 1, range_key = None), callback = None, attributes = get_attrs) 
        if get_res.attributes : 
            self.assertEqual (len (get_res.attributes), len (new_attrs)) 
            for (k, v) in new_attrs.items () : 
                self.assertEqual (get_res.attributes [k], v) 
else : 
            self.assertEqual (get_res.attributes, { 
                
}) 
attrs = { 
        'num' : 1, 
        'str' : 'test', 
        'num_set' : list ([1, 2, 3]), 
        'str_set' : list (['a', 'b', 'c']), 
} 
    self._client.PutItem (table = 'LocalTest2', key = DBKey (hash_key = 1, range_key = None), attributes = self, callback = None) 
    _VerifyUpdate ({ 
        'num' : UpdateAttr (value = 2, action = 'PUT'), 
}, ['num'], { 
        'num' : 2, 
}, 'NONE', { 
        
}) 
    _VerifyUpdate ({ 
        'num' : UpdateAttr (value = 2, action = 'ADD'), 
}, ['num'], { 
        'num' : 4, 
}, 'UPDATED_NEW', { 
        'num' : 4,

    _VerifyUpdate ({

        'num' : UpdateAttr (value = (- 1), action = 'ADD'), 
        'num_set' : UpdateAttr (value = list ([4, 5, 6]), action = 'PUT'),

        'num' : (- 1), 
        'num_set' : list ([4, 5, 6]), 
}, 'ALL_OLD', { 
        'str' : 'test', 
        'num_set' : list ([1, 2, 3]), 
        'str_set' : list (['a', 'b', 'c']), 
}) 
    _VerifyUpdate ({ 
        'str' : UpdateAttr (value = 'new_test', action = 'PUT'), 
        'num_set' : UpdateAttr (value =...

    
    

    Fix the buggy line: self._client.PutItem (table = 'LocalTest2', key = DBKey (hash_key = 1, range_key = None), attributes = self, callback = None)

#Here is Python code to fix the buggy line: self.
