Question

我正在制作一个程序，它从服务器上擦除总线信息，并通过Facebook Messenger发送给用户。它工作正常，但我正在尝试添加功能，将很长的时间表分成单独的消息。要做到这一点，我必须制作一个if语句来检测真正的长时间表，拆分它们并从我的主文件中调用send_message函数，app.py

以下是app中函数的一部分，其中包含我需要提取的变量：

for messaging_event in entry["messaging"]:

                if messaging_event.get("message"):  # someone sent us a message

                    sender_id = messaging_event["sender"]["id"]        # the facebook ID of the person sending you the message
                    recipient_id = messaging_event["recipient"]["id"]  # the recipient's ID, which should be your page's facebook ID
                    message_text = messaging_event["message"]["text"]  # the message's text
                    tobesent = messaging_event["message"]["text"]

                    send_message(sender_id, fetch.fetchtime(tobesent))

这里是fetch中的if语句，它检测长消息，拆分它们并从另一个文件send_message调用app.py函数：

if len(info["results"]) > 5:
            for i, chunk in enumerate(chunks(info, 5), 1):
                app.send_message((USER ID SHOULD BE HERE, 'Listing part: {}\n \n{}'.format(i, chunk)))

我正在尝试从send_message调用app.py函数，但它需要两个参数sender_id和消息文本。如何从此函数中获取sender_id变量并在fetch中使用它？我已经尝试返回它并调用该函数，但它对我不起作用。

编辑：错误

Traceback (most recent call last):
  File "bus.py", line 7, in <module>
    print fetch.fetchtime(stopnum)

    send_message((webhook(),'Listing part: {}\n \n{}'.format(i, chunk)))

This typically means that you attempted to use functionality that needed
an active HTTP request.  Consult the documentation on testing for
information about how to avoid this problem.

如何从Python中的函数中提取变量？
