python 强制关闭线程

        # and you should call it again with exc=NULL to revert the effect"""

        while True:

            print("线程 进行中")


if __name__ == "__main__":
    t = TestThread()
    t.start()  # 开启启动

    time.sleep(2)  # 等待线程进行2秒时间
    stop_thread(t)  # 结束线程 调用函数即可
    print("线程 结束")
