python多线程，获取多线程的返回值

# coding=utf-8

import threading
from time import ctime, sleep

# 多线程如何返回值
class MyThread(threading.Thread):

    def __init__(self,func,args=()):
        super(MyThread,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  # 如果子线程不使用join方法，此处可能会报没有self.result的错误
        except Exception:
            return None
