python定时循环执行函数，定时循环执行脚本

先上代码：

import urllib.request
import time
def cycle():
    urllist = [
        '111809145',
        '111811190',

    count = 0
    baseUrl = 'https://blog.csdn.net/qq_31754591/article/details/'
    for url in urllist:
        req = urllib.request.Request(baseUrl + url)
        resp = urllib.request.urlopen(req)
        # data读取页面吧
        data = resp.read().decode('utf-8')
        count = count+1
        print("次数：", count)
def sleeptime(hour, min, sec):
    return hour * 3600 + min * 60 + sec
second = sleeptime(0, 0, 180)
while 1 == 1:
    time.sleep(second)
    cycle()
# 这是隔180秒执行一次
