python定时检查某个进程是否已经关闭的方法
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：
importthreading
importtime
importos
importsubprocess
defget_process_count(imagename):
p=os.popen('tasklist/FI"IMAGENAMEeq%s"'%imagename)
returnp.read().count(imagename)
deftimer_start():
t=threading.Timer(120,watch_func,("isrunning..."))
t.start()
defwatch_func(msg):
print"I'mwatch_func,",msg
ifget_process_count('main.exe')==0:
printsubprocess.Popen([r'D:\shuaji\bin\main.exe'])
timer_start()
if__name__=="__main__":
timer_start()
whileTrue:
time.sleep(1)
希望本文所述对大家的Python程序设计有所帮助。
