python - Tweepy not working -

so trying run tweepy script collect tweets. i've setup database i'm running error.

starting... started user: user1 exception in thread thread-1: traceback (most recent call last): file     "/library/frameworks/python.framework/versions/2.7/lib/python2.7/threading.py",       line 810, in __bootstrap_inner self.run() file "/library/frameworks/python.framework/versions/2.7/lib/python2.7/threading.py", line 763, in run self.__target(*self.__args, **self.__kwargs) file "build/bdist.macosx-10.6-intel/egg/tweepy/streaming.py", line 414, in filter self.body['follow'] = u','.join(follow).encode(encoding) typeerror: sequence item 0: expected string or unicode, int found 

edit: script using: urllib import urlencode_noplus _noplus not in urllib why deleted code. although suspect causing error..
