3.when i change

    def read(self,key) -> dict:
        for key, value in self.__dict.iteritems():
            print(key, value)        
        with self.__lock:
            try:
                val = self.__dict[key]
                print(222,val)
            except:

            # if key not in self.__dict:
                print(111,self.__dict)

                raise KeyError("error: given key does not exist in database. Please enter a valid key") #raising a key error
            else:
                mydict = json.loads(self.__dict[key])

                return mydict

output
