Python runs the method of the specified function every N seconds

This example shows how python runs a specified function every N seconds. Share with you for your reference. The details are as follows:

This is a timer like effect, every specified number of seconds to run the specified function, thread implementation, simple code.

import os

import time

def print_ts(message):

    print "[%s] %s"%(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime()), message)

def run(interval, command):

    print_ts("-"*100)

    print_ts("Command %s"%command)

    print_ts("Starting every %s seconds."%interval)

    print_ts("-"*100)

    while True:

        try:

            # sleep for the remaining seconds of interval

            time_remaining = interval-time.time()%interval

            print_ts("Sleeping until %s (%s seconds)..."%((time.ctime(time.time()+time_remaining)), time_remaining))

            time.sleep(time_remaining)

            print_ts("Starting command.")

            # execute the command

            status = os.system(command)

            print_ts("-"*100)

            print_ts("Command status = %s."%status)

        except Exception, e:

            print e

if __name__=="__main__":

    interval = 5

    command = r"ipconfig"

    run(interval, command)
