old_keys = [str(key1), str(key2),str(key3)] new_keys = [str(db.Key(i)) for i in old_keys] new_keys would be new_keys = [db.Key(i) for i in old_keys] assuming new_keys has been declared as db.ListProperty(db.Key) Rgds Tim -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
