python 使用线程池来同时执行多个函数

from concurrent.futures import ThreadPoolExecutor, as_completed

def handle(self, start, end):
    tasks = {
        TypeId.campaign.value: (self.get_campaign_report, (start, end), {})  # 添加空的关键字参数字典
    }
    results = []
    with ThreadPoolExecutor(max_workers=5) as executor:
        # 提交所有任务到线程池
        futures = []
        for task, args, kwargs in tasks.values():  # 现在解包三元组
            future = executor.submit(task, *args, **kwargs)
            futures.append(future)

        # 处理完成的任务（带异常处理）
        for future in as_completed(futures):
            try:
                result = future.result()
                results.append(result)
                print(f"任务成功完成，结果: {result}")  # 添加调试输出
            except Exception as e:
                print(f"任务执行出错: {e}")  # 捕获并打印异常
                results.append({})  # 或者添加错误信息到结果
    return dict(zip(tasks.keys(), results))
