Python で MySQL ストアド プロシージャから結果を取得する方法

CREATE PROCEDURE `mytestdb`.`getperson` (IN personid INT)
BEGIN
   select person.person_id,
          person.person_fname,
          person.person_mi,
          person.person_lname,
          person.persongender_id,
          person.personjob_id
     from person
    where person.person_id = personid;
END

import mysql.connector

cnx = mysql.connector.connect(user='root', host='127.0.0.1', database='mytestdb')
cnx._open_connection()
cursor = cnx.cursor()

cursor.callproc("getperson", [1])
people = cursor.fetchall()

for person in people:
    print(person)

cnx.close()

for result in cursor.stored_results():
    people = result.fetchall()
