子进程Popen卡住了

Question

def hello(): while True: print 'subprocess = ' + str(os.getpid()) time.sleep(1) def killPid(pid): print 'kill ' + str(pid) os.system("taskkill" + ' /T /F /pid '+ str(pid)) p = subprocess.Popen(hello()) # p = subprocess.Popen("ping 10.193.101.34", shell=True) print 'after subprocess' t = threading.Timer(3.0, killPid, args=(p.pid,)) t.start() # after 3 seconds, "hello, world" will be printed

Answer 1

它表明您希望将函数hello（）作为一个进程来执行。要做到这一点，你可以试着打电话给波本类似的东西

["python","-m",__file__,"-c","hello()"] 

运行执行hello函数的python解释器的新实例
