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。
