TwythonStreamer：OR不能用作过滤器

Question

I'm not sure why the following code does not return any result. If I put streamer.statuses.filter(track = 'data') , then it outputs tweets. However, if I use join with OR , it does not work, though I am using 'data' as one of options. Finally, if I use track=keywords , it neither works.

from twython import TwythonStreamer
from collections import Counter

tweets = []

class TweetStreamer(TwythonStreamer):
    def on_success(self, data):
        if 'text' in data:
            tweets.append(data['text'].encode('utf-8'))
            print data['text'].encode('utf-8')
        if len(tweets)>10:
            self.disconnect()

    def on_error(self, status_code, data):
        print status_code
        self.disconnect()

CONSUMER_KEY = "..."
CONSUMER_SECRET = "..."
ACCESS_TOKEN = "..."
ACCESS_TOKEN_SECRET = "..."

streamer = TweetStreamer(CONSUMER_KEY, CONSUMER_SECRET,
                         ACCESS_TOKEN, ACCESS_TOKEN_SECRET)

keywords = ['data','information']
track = " OR ".join(keywords)

streamer.statuses.filter(track = track)

Answer 1

You have to use the Twitter API in a correct way.

From the doc :

• For logical AND separate with space: "data information" == " ".join(['data', 'information'])
• For logical OR separate with comma: "data,information" == ",".join(['data', 'information'])
