python多线程获取线程函数的返回结果

import threading

    def __init__(self, func, name="", *args, **kwargs):
        threading.Thread.__init__(self)
        self.name = name
        self._target = func

        self._kwargs = kwargs

    def run(self):  # 重写方法
        try:
            if self._target:
                self.result = self._target(*self._args, **self._kwargs)
        finally:
            del self._target, self._args, self._kwargs

    def get_result(self):
        try:
            return self.result  # 先start  再join 才能获取
        except Exception:
            return None
