Comment gérer les connexions MySQL avec le multithreading Python

Voici un exemple utilisant le multithreading deal mysql en Python, je ne connais pas votre table et vos données, donc, juste changer le code peut aider :

import threading
import time
import MySQLdb

Num_Of_threads = 5

class myThread(threading.Thread):

    def __init__(self, conn, cur, data_to_deal):
        threading.Thread.__init__(self)
        self.threadID = threadID
        self.conn = conn
        self.cur = cur
        self.data_to_deal

    def run(self):

        # add your sql 
        sql = 'insert into table id values ({0});'
        for i in self.data_to_deal:
            self.cur.execute(sql.format(i))
            self.conn.commit()

threads = []
data_list = [1,2,3,4,5]

for i in range(Num_Of_threads):
    conn = MySQLdb.connect(host='localhost',user='root',passwd='',db='')
    cur = conn.cursor()
    new_thread = myThread(conn, cur, data_list[i])

for th in threads:
    th.start()

for t in threads:
    t.join()
