python-3.x - 如何只获得正分？

Question

我是情绪分析的新手。我只想得到积极的分数，而不是像复合，否定，pos，中性。谁能帮我实现这个目标？

sid = SentimentIntensityAnalyzer()
ss = sid.polarity_scores(sentence) 

提前致谢。

Answer 1

Based on the source code, the method returns a dictionary with shape:

{"neg" : ..., "neu" : ..., "pos" : ..., "compound" : ...}

So you can simply use:

sid = SentimentIntensityAnalyzer()
ss = sid.polarity_scores(sentence)['pos'] # the positive score

Here ['pos'] fetches the value that is associated with the 'pos' key.
