The examples in this article describe the implementation method of periodic execution of Python functions. Share it with everyone for your reference, the details are as follows:

You need to use python’s sched module:

#coding=utf-8
import time,sched,os
#初始化sched模块的scheduler类
#第一个参数是一个可以返回时间戳的函数,第二个参数可以在定时未到达之前阻塞。
s = sched.scheduler(time.time,time.sleep)
#被周期性调度触发的函数
def event_func():
  print "Current Time:",time.time()
#enter四个参数分别为:间隔事件、优先级(用于同时间到达的两个事件同时执行时定序)、被调用触发的函数,给他的参数(注意:一定要以tuple给如,如果只有一个参数就(xx,))
def perform(inc):
  s.enter(inc,0,perform,(inc,))
  event_func()
def mymain(inc=60):
  s.enter(0,0,perform,(inc,))
  s.run()
# if __name__ == "__main__":
  # mymain()
