#!/usr/bin/env python
# -*- coding:utf-8 -*-
from concurrent.futures import ThreadPoolExecutor
#线程池,导入模块
import time

def task(hostname):
    ‘‘‘
    假设这里是要提交的任务
    :param hostname: 
    :return: 
    ‘‘‘
    time.sleep(2)
    print(hostname)

#创建线程池线程数自定义，要看主机性能，例如创建20个线程
pool = ThreadPoolExecutor(20)

for i in range(1,101):
    #100个任务
    hostname = ‘c{}.com‘.format(i)
    pool.submit(task,hostname
