python获取多线程的返回值

import threading

import time


class MyThead(threading.Thread):
    def __init__(self,func,args=()):
        super(MyThead,self).__init__()
        self.func = func
        self.args = args

    def run(self):
        self.result = self.func(*self.args)

    def get_result(self):
        try:
            return self.result
        except:
            raise None

def m(n):
    time.sleep(3)
    return n

li=[]
for i in range(10):
    t = MyThead(m,args=(i,))
    li.append(t)
    t.start()


for i in li:
    i.join()
    print(i.get_result())
