python定時檢查某個進程是否已經關閉的方法

 　　本文實例講述了python定時檢查某個進程是否已經關閉的方法。分享給大家供大家參考。具體如下：

　　?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 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:shuajibinmain.exe']) timer_start() if __name__ == "__main__": timer_start() while True: time.sleep(1)

　　希望本文所述對大家的Python程序設計有所幫助。
