Sådan håndteres MySQL-forbindelse(r) med Python multithreading

Her er et eksempel ved hjælp af multithreading deal mysql i Python, jeg kender ikke din tabel og data, så bare ændring af koden kan hjælpe:

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()
