从评论列中提取句子并将其添加到新列中，为每个新句子重复其他行

Question

我有 3 列。评论、日期和评论评级。我想将评论拆分成句子并在新列下添加句子，但其他行应根据句子数量重复。

例如

Date          Review_Rating           Review                      Sentence
12-02-2021        5          ram is good. ram is intelligent       ram is good.
12-02-2021        5          ram is good. ram is intelligent       ram is intelligent

Answer 1

IIUC，可以使用assign和explode:

>>> df

         Date  Review_Rating                           Review
0  12-02-2021              5  ram is good. ram is intelligent


>>> df.assign(Sentence=df['Review'].str.split(r'\.\s*')).explode('Sentence')

         Date  Review_Rating                           Review            Sentence
0  12-02-2021              5  ram is good. ram is intelligent         ram is good
0  12-02-2021              5  ram is good. ram is intelligent  ram is intelligent
