Question

我正试图在数据框中为单个列循环10K行，试图对Twitter数据进行情绪分析：

twitter_data = pd.DataFrame(pd.read_csv("/Users/Stu/Jupyter/Sentiment Score Test 4.csv", encoding = "latin-1"))

screenName = twitter_data.screenName
tweet = twitter_data.text
favorites = twitter_data.favoriteCount
retweets = twitter_data.favoriteCount

tweet.head()

0    Finally finished the first season of Mr. Robot...
1              @DavidVonderhaar thoughts on Mr. Robot?
2    I liked a @YouTube video from @seasonedreviews...
3    Am I sane enough not to tweet about Mr Robot f...
4    the guy from queer as folk is in mr robot omg ...
Name: text, dtype: object

然后我会从我创建的模块（通过tutes的帮助）中使用我的情感函数打印出我想要的值：

print(tweet[0])
sentiment_value, confidence = s.sentiment(tweet[0])
print(sentiment_value)
print(confidence)

Mr. Robot had a perfect season on Rotten Tomatoesâ¦ http://t.co/CPsZUid5knââ¦â¦â¦â¦ http://t.co/AVGzjA7KGKââ¦â¦â¦â¦â¦â¦â¦ http://t.co/2iB0vX0mva

1.0

但是，当我尝试通过for循环推送此数据以通过执行以下操作打印出情绪值时：

for t in tweet:
    sentiment_value, confidence(s.sentiment(tweet[t]))
    print(sentiment_value)

我被抛出以下错误：

During handling of the above exception, another exception occurred:

KeyError: 'Finally finished the first season of Mr. Robot.Pure, fucked up genius, love everything about this twisted show.'

如何解决此错误？

Answer 1

我认为

sentiment_value, confidence(s.sentiment(tweet[t]))

实际应该是

sentiment_value, confidence = s.sentiment(t)

请记住，循环正在为你做索引。
