Python 3 : find item in list and answer based on that

Question

我正在尝试制作一个 python 脚本，使用 fbchat 监听 Facebook 聊天并搜索单词 'cf'。如果在聊天中检测到该单词，我想发送一条预定义消息 Answer1。请参阅下面的代码和我得到的错误:

from fbchat import log, Client
from fbchat.models import *

wordImLookingFor = ['cf']

Answer1 =['Hello! how can i help you']

# Subclass fbchat.Client and override required methods
class EchoBot(Client):
    def onMessage(self, author_id, message_object, thread_id, thread_type, **kwargs):
        self.markAsDelivered(thread_id, message_object.uid)
        self.markAsRead(thread_id)

        log.info("{} from {} in {}".format(message_object, thread_id, thread_type.name))

        # If you're not the author, echo
        if author_id != self.uid:
            if word in message_object:
                print("The word is in the list!")
                self.send(Message(text=answer1), thread_id=thread_id, thread_type=ThreadType.USER)


             else:
                print("The word is not in the list!")



client = EchoBot('user', 'pass')


client.listen()

Exception in parsing ... Traceback (most recent call last): ... File "C:/Users/John/Downloads/fbd2.py", line 22, in onMessage if word in message_object: TypeError: argument of type 'Message' is not iterable

Answer 1

这是 fbchat.models.Message 的 API

我相信您正在寻找文本字段

if word in message_object.text:
    print("The word is in the list!")

简单的解决方案

对于您的下一个错误，in 关键字需要单个字符串，而不是字符串列表。由于您要在消息中查找多个关键字，因此请对列表中的每个单词执行该 case 语句。

if author_id != self.uid:
    for word in wordImLookingFor:
        if word in message_object.text:
            print("The word is in the list!")
            self.send(Message(text=answer1), thread_id=thread_id, thread_type=ThreadType.USER)
        else:
            print("The word is not in the list!")

规模化解决方案

由于您最终将搜索一组多个关键字，并且可能每个关键字都应得出不同的答案，因此您可以通过创建关键字:答案字典来节省一些复杂性。

keywords = {'cf': 'Hello! how can i help you', 'key2': 'Answer2'}

class EchoBot(Client):
    def onMessage(self, author_id, message_object, thread_id, thread_type, **kwargs):
        self.markAsDelivered(thread_id, message_object.uid)
        self.markAsRead(thread_id)

        log.info("{} from {} in {}".format(message_object, thread_id, thread_type.name))

        if author_id != self.uid:
            for word in message_object.text.split():
                try:
                    self.send(Message(text=keywords[word]), thread_id=thread_id, thread_type=ThreadType.USER)
                    print(word + "is in the list!")
                except KeyError:
                    print(word + "is not in the list!")
