Tweepy：在Stream Listener中调用api.update_status

Question

我有一个Tweepy侦听器，以流式传输包含特定用户的推文（例如，我想检测提及）。我的问题是在update_status类内部时如何在api中调用TwitterListener方法？如何将它（api实例）作为变量传递？

class TwitterAuthenticator():
    def authenticate_twitter_app(self):
        auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
        auth.set_access_token(access_token, access_token_secret)
        return auth


class TwitterListener(StreamListener):
    """
    This a basic listener class that just prints received tweets
    """
    def __init__(self,hash_list):

    def on_data(self,data):
        try:
            #parse data 

            if condition: 
                #this is where the PROBLEM is located          
                api.update_status(status='some text')

        except BaseException as e:
            print("Error on_data: %s" % str(e))
        return True
    def on_error(self,status):
        if status == 420:
            # Returning False on_data method in case rate limit
            return False

class TwitterStreamer():
    """
    Class for streamming and processing line tweets.
    """
    def __init__(self):
        self.twitter_authenticator = TwitterAuthenticator()
        pass
    def stream_tweets(self,hash_list):
        # This handels Twitter authentication and the connection to the Twitter Streaming API
        listener = TwitterListener(hash_list)
        auth = self.twitter_authenticator.authenticate_twitter_app()
        api = tweepy.API(auth,wait_on_rate_limit=True, wait_on_rate_limit_notify=True, compression=True)
        stream = Stream(auth,listener)
        stream.filter(track=hash_list)

hash_list = ['user_screen_name']

twiiter_streamer = TwitterStreamer()
twiiter_streamer.stream_tweets(hash_list)
