for-loop - tweepy 中的循环错误

Question

我最近一直在玩 tweepy，我试图拉动给定用户的关注者和关注者。

 followingids = []
 followids = []
 userid = "Someone"#sets target

 for page in tweepy.Cursor(api.followers_ids, screen_name=userid).pages():#gets the followers for userID
     followingids.extend(page)
     time.sleep(60)#keeps us cool with twitter


  for page in tweepy.Cursor(api.friends_ids, screen_name=userid).pages():#gets the followers for userID
     followids.extend(page)
     time.sleep(60)#keeps us cool with twitter

 #where weirdness starts 
 print len(followingids), "followers have been gathered from", userid 
 print len(followids), " users are followed by ", userid

 followingusers = api.lookup_users(user_ids=followingids)#ieterates through the list of users and prints them
 followedusers = api.lookup_users(user_ids=followids) #<does not work but above does 


 print "users of following", userid 
 for u in followingusers:
     print u.screen_name


 print "users followed by", userid
 for s in followedusers:
     print s.screen_name

第二个 print for 循环给出了这个错误:

 Traceback (most recent call last):
   File "twitterBot.py", line 30, in <module>
     followedusers = api.lookup_users(user_ids=followids) #<does not work but above does 
   File "/usr/local/lib/python2.7/dist-packages/tweepy/api.py", line 160, in lookup_users
     return self._lookup_users(list_to_csv(user_ids), list_to_csv(screen_names))
   File "/usr/local/lib/python2.7/dist-packages/tweepy/binder.py", line 230, in _call
     return method.execute()
   File "/usr/local/lib/python2.7/dist-packages/tweepy/binder.py", line 203, in execute
     raise TweepError(error_msg, resp)
 tweepy.error.TweepError: [{u'message': u'Too many terms specified in query.', u'code': 18}]

followedusers 和 followingusers 都有 twitter id 号码，我直接剪切并粘贴了用于打印的代码，那么为什么第一个有效而第二个无效？

Answer 1

您的代码未损坏，不一定。推特limits you to returning 100 users使用 GET 用户查找(这是 api.lookup_users 所做的)。请求超过 100 将导致 Tweepy 错误代码 18，您仅针对 followed users 查询获得该错误代码，这看起来像您查询的用户 followed more than 100 users 但 followed by less than 100.

一个简单的解决方案是迭代搜索关注者/关注用户的列表(如果您希望代码更健壮，这两者都是安全的)。每 100 个用户标识进行一次迭代，并使用 api.lookup_users 一次最多查找 100 个。
