你先建立一个Queue,把Queue当参数给亏薯姿你的myThread,手扰然后myThread不要返回值,而是put在Queue里面。在for i in threads里用Queue.get取销绝出来。Queue是thread safe的,可以放心用。

定义一个全局变量存放每个线程的返回值。

class myThread(threading.Thread):
def __init__(self):
self.ret = None
def start(self):
pass
def run(self):
self.ret = ...
def __init__(self):
self.ret = None
def start(self):
pass
def run(self):
self.ret = ...
