6.使用隐藏属性_stop() 为了杀死线程,我们使用了隐藏函数_stop(),该函数没有文档说明,但可能会在下一版本的python中消失。 # Python program killing# a thread using ._stop()# functionimporttimeimportthreadingclassMyThread(threading.Thread):# Thread class with a _stop() method.# The thread itself ha...
threading.Thread.__init__(self) self.stop = False defrun(self): whilenotself.stop: somefunction() 这种方式相比第一种而言,又有一点不足:kill生效的时限,最大等于somefunction执行一遍所花的时间。 而第一种方式,在下一句python语句执行时就会生效。
