Как заставить python3 выполнить содержимое sql файла?

import os
from mysql.connector import connect, Error

MYSQL_PASSWORD = os.environ.get("MYSQL_ROOT_PASSWORD")

try:
    cnx = connect(user="root", password=MYSQL_PASSWORD, host="mysql")
    with open('bootstrap.sql', 'r') as sql:
        with cnx.cursor() as cursor:
            cursor.execute(sql.read(), multi=True)
        cnx.commit()
except Error as err:
    print("Error: " + err)
    exit(1)
