Question

请帮助，我对此非常陌生，需要为西南航空收集推文。我做错了什么？什么＆amp;如果我想要一个特定的公司名称，我该在哪里写？谢谢。

 line 32, in get_all_tweets
    oldest = alltweets[-1].id - 1
    IndexError: list index out of range

    auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
    auth.set_access_token(access_key, access_secret)
    api = tweepy.API(auth)
    alltweets = []  
    new_tweets = api.user_timeline(screen_name = screen_name,count=200)

    alltweets.extend(new_tweets)

    oldest = alltweets[-1].id - 1

    while len(new_tweets) > 0:
        print "getting tweets before %s" % (oldest)

        new_tweets = api.user_timeline(screen_name = screen_name,count=200,max_id=oldest)

        alltweets.extend(new_tweets)

        oldest = alltweets[-1].id - 1

    with open('%s_tweets.csv' % screen_name, 'wb') as f:
        writer = csv.writer(f)
        writer.writerow(["id","created_at","text"])
        writer.writerows(outtweets)

Answer 1

此错误清楚地表明您的列表alltweets为空。这意味着api.user_timeline(screen_name = screen_name,count=200)的返回值为[]。

可能是因为一些不同的问题。其中一个可能是您使用的screen_name有拼写错误。

Answer 2

打印new_tweets并查看您获得的内容。您的错误很可能是由于没有找到new_tweets，您实际上是在下载数据吗？否则，您将尝试获取空列表的最后一个元素，并获得该错误。

alltweets = []
alltweets.extend([]) # if new_tweets is empty will cause alltweets to remain empty
oldest = alltweets[-1].id - 1 # can't get the last element of an empty list.

哦，我正在谈论while循环之前的那一行。

Python shell给出了错误IndexError：list index超出范围
