如果收到消息，您如何回复发件人？ （在if语句中）

Question

我对Python很新，我正在写一个脚本，当有人向你发送消息时发送Skype消息（并且它根据进程是否存在而改变消息。）我正在努力让python识别收到的消息。我已经看到了另一篇文章，但我很难将其纳入if语句。 如果需要，代码包含在下面。

import Skype4Py
import sys
import os
while 0 == 0: #infinite loop
    if """user sends message to me""":
        if #process is open (Still haven't figured this out, either!)
            print("Process Found")
            client = Skype4Py.Skype()
            client.Attach()
            user = ChatMessage.Sender #may need changing
            message = 'SERVER ONLINE'
            client.SendMessage(user, message)
            print("Message sent to", ChatMessage.Sender)
        else:
            print("Process Non-Existant")
            client = Skype4Py.Skype()
            client.Attach()
            user = ChatMessage.Sender #same as above
            message = 'SERVER OFFLINE'
            client.SendMessage(user, message)
            print("Message sent to", ChatMessage.Sender)
    else:
        print("Awaiting Message")
else:
    print("Physics is broken.")

这是我有多远。 谢谢 - James Whybrow
