详解Python3定时器任务代码
作者:撒欢
这篇文章主要介绍了Python3定时器任务代码,本文通过实例代码给大家介绍的非常详细,具有一定的参考借鉴价值,需要的朋友可以参考下
使用threading写的一个定时器任务demo:
import time import sys import signal import datetime import threading #定时器 def schedule_update(): t = threading.Timer(0, event_func) t.setDaemon(True) t.start() #执行函数 def event_func(): now_time = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S') print(now_time) exec_update() #update_openvas_dbs_from_cache() interval_time = delay_time() t = threading.Timer(interval_time, event_func) t.setDaemon(True) t.start() #取时间点 def delay_time(): # now time now_time = datetime.datetime.now() # tomorrow time next_time = now_time + datetime.timedelta(days=+1) next_year = next_time.date().year next_month = next_time.date().month next_day = next_time.date().day # get tomorrow 00:00 next_time = datetime.datetime.strptime(str(next_year)+"-"+str(next_month)+"-"+str(next_day)+" 00:00:00", "%Y-%m-%d %H:%M:%S") # get secondes delay_time = (next_time - now_time).total_seconds() return delay_time def quit_sys(signum, frame): sys.exit() #接收C if __name__ == "__main__": try: signal.signal(signal.SIGINT, quit_sys) signal.signal(signal.SIGTERM, quit_sys) schedule_update() print("schedule_update server starting up...\nHit Ctrl-C to quit.\n") while 1: time.sleep(1) except Exception as e: print(e)
