如上代碼，線程池提交任務(wù)，默認(rèn)讀到的line為空時(shí)退出while循環(huán)，此時(shí)主線程終止，程序退出，調(diào)用shutDown（）方法等待線程池中的任務(wù)執(zhí)行完再退出程序，shutDown源碼如下，默認(rèn)等待，可以設(shè)置為不等待
def shutdown(self, wait=True):
with self._shutdown_lock:
self._shutdown = True
self._work_queue.put(None)
if wait:
for t in self._threads:
t.join(sys.maxint)
