Python多线程(生成动态参数)

Python多线程方法如下：

import threading
import datetime
import pymssql
import time
from faker import Faker


def insert_db():
    for i in range(100):
        for j in range(100):
            print(j)
            time1 = datetime.datetime.now()
            fake = Faker(locale='zh_CN')
            name = fake.name()
            ssn = fake.ssn()
            card_number = fake.credit_card_number()
            phone_number = fake.phone_number()
            print(datetime.datetime.now() - time1)
            print(name, ssn, card_number, phone_number)
            conn = pymssql.connect(host='ip', user='sa', password='password', database='db',
                                   charset='UTF-8')
            cur = conn.cursor()
            sql = 'This is the sql'
            print(sql)

            cur.execute(sql)
            conn.commit()


        cur.close()
        conn.close()


exitFlag = 0


class myThread(threading.Thread):
    def __init__(self, threadID, name, counter):
        threading.Thread.__init__(self)
        self.threadID = threadID
        self.name = name
        self.counter = counter

    def run(self):
        print("开始线程：" + self.name)
        print_time(self.name, self.counter, 5)
        insert_db()
        print("退出线程：" + self.name)


def print_time(threadName, delay, counter):
    while counter:
        if exitFlag:
            threadName.exit()
        time.sleep(delay)
        print("%s: %s" % (threadName, time.ctime(time.time())))
        counter -= 1


for i in range(50):
    # 创建新线程
    locals()['thread' + str(i)] = myThread(i, "Thread-%s" % i, i)

for i in range(50):
    # 开启新线程
    locals()['thread' + str(i)].start()

for i in range(50):
    locals()['thread' + str(i)].join()

print("退出主线程")

locals()['thread' + str(i)] 这个方法可以生成thread1，thread2，thread3...这些参数

Faker 是python造数常用的一个库
