python获取子线程结果

from threading import Thread


class MyThread(Thread):
    def __init__(self, func, args=()):
        Thread.__init__(self)
        self.func = func
        self.args = args
        self.result = self.func(self.args)
    
    # 获取子线程结果
    def result(self):
        # 必须阻塞子线程才能获取到结果
        Thread.join(self)
        try:
            return self.result
        except Exception as e:
            print('获取子线程结果失败: %s' % e)
            return None


def test(arg):
    return arg


if __name__ == '__main__':
    # 开启子线程
    thread = MyThread(test, ('param',))
    thread.setDaemon(True)
    thread.start()
    # 获取返回结果
    result = MyThread.result(thread)
    print(result)
    input(111)
