默认的thread.join()方法只是等待线程函数结束，没有返回值，我们可以在此处返回函数的运行结果，代码如下：from threading import Thread def foo(arg):return arg class ThreadWithReturnValue(Thread):def run(self):if self._target is not None:self._return = self._target(*self._args,**self._kwargs)de...

threading模块中加入守护线程概念,如果被指明为守护线程后主线程退出后不会等待守护线程执行完毕才吐出。整个Python 程序(可以解读为:主线程)将在所有非守护线程退出之后才退出,换句话说,就是没有剩下存活的非守护线程时。 主线程和子线程分别是什么?举例?
