i have had problem to deploy my python app

[Luis Guillermo Barrios P]

      this is my code:

 import pymysql

       

        self.host = settings.DATABASES['default']['HOST']

        self.user = settings.DATABASES['default']['USER']

        self.password = settings.DATABASES['default']['PASSWORD']

        self.database = settings.DATABASES['default']['NAME']

        try:

            miConexion = pymysql.connect(host=self.host, user=self.user,  password=self.password, db=self.database)

            

        except (pymysql.err.OperationalError, pymysql.err.InternalError) as e:

            print("Ocurrió un error al conectar: ", e)

        self.cur = miConexion.cursor()

    def query(self,sql):

        self.cur.execute( sql )

        results = self.cur.fetchall()

        return results

    def update(self,sql):

        self.cur.execute( sql )

and this is the error:
