Twitter流错误

Question

我正试图通过twitter API从twitter上收集推文。我在twitterStream语句中收到错误，如下所示：我如何解决它。

from tweepy.streaming import StreamListener
from tweepy import OAuthHandler
from tweepy import Stream
import time

ckey = 'serhsrtjhath'
csecret = 'sdfhszdjsrztj'

atoken = 'aerhyaetjsjk'
asecret = 'srtjsrkisk'

class StdOutListener(StreamListener):
def on_data(self, data):
        try:        
        #print data
        saveFile = open('tweetdb.csv', 'a')
        saveFile.write(data)
        saveFile.write('\n')
        saveFile.close()
        return True
        except BaseException, e:
        print 'failed ondata,',str(e)
        time.sleep(5)

    def on_error(self, status):
        print status
l = StdOutListener()
auth = OAuthHandler(ckey, csecret)
auth.set_access_token(atoken, asecret)

twitterStream = Stream(auth, l)
twitterStream.filter(track=["Paris"])

错误：

Traceback (most recent call last):
  File "scrape_data.py", line 34, in <module>
    twitterStream = Stream(auth, l)
TypeError: __init__() takes at least 4 arguments (3 given)

注意：我使用Python 2.7。
