我正在尝试使用nltk.sentiment.vader中的sentimentIntensityAnalyzer（）对推文进行情感分析
sid = SentimentIntensityAnalyzer()
listy = []
for index, row in data.iterrows():
ss = sid.polarity_scores(row["Tweets"])
listy.append(ss)
se = pd.Series(listy)
data['polarity'] = se.values
display(data.head(100))
这是生成的dataFramee：

为了对极性列中的“ neg”，“ pos”，“ neu”和“ compound”实体进行统计分析，我想将数据分为四个不同的列。为此，我使用了：
list_pos= []
list_neg = []
list_comp = []
list_neu = []
for index, row in data.iterrows():
list_pos.append(row['polarity']['pos'])
list_neg.append(row['polarity']['neg'])
list_comp.append(row['polarity']['compound'])
list_neu.append(row['polarity']['neu'])
se_pos = pd.Series(list_pos)
se_neg = pd.Series(list_neg)
se_comp = pd.Series(list_comp)
se_neu = pd.Series(list_neu)
data['positive'] = se_pos.values
data['negative'] = se_neg.values
data['compound'] = se_comp.values
data['neutral'] = se_neu.values
结果dataFrame：
Tweets polarity positive negative compound neutral

是否有更简洁的方法来实现类似的dataFrame？也许使用lambda函数？谢谢您的帮助！
