本文实例讲述了python定时检查某个进程是否已经关闭的方法。分享给大家供大家参考。具体如下：
import threading
import time
import os
import subprocess
def get_process_count(imagename):
p = os.popen(‘tasklist /fi “imagename eq %s”‘ % imagename)
return p.read().count(imagename)
def timer_start():
t = threading.timer(120,watch_func,(“is running…”))
t.start()
def watch_func(msg):
print “i’m watch_func,”,msg
if get_process_count(‘main.exe’) == 0 :
print subprocess.popen([r’d:\shuaji\bin\main.exe’])
timer_start()
if __name__ == “__main__”:
timer_start()
while true:
time.sleep(1)
希望本文所述对大家的python程序设计有所帮助。
