使用python提取句子 [英] extract a sentence using python

问题描述

如果某个句子中存在某个特定单词，我想提取出确切的句子.谁能让我知道如何使用python做到这一点.我使用了concordance()，但是它只打印单词匹配的行.

I would like to extract the exact sentence if a particular word is present in that sentence. Could anyone let me know how to do it with python. I used concordance() but it only prints lines where the word matches.

推荐答案

快速提醒一下:断句实际上是一件非常复杂的事情，句号规则也有例外，例如先生".或博士"还有各种各样的句子结尾标点符号.但是例外也有例外(例如，如果下一个单词用大写字母表示，并且不是专有名词，那么Dr.可以结束一个句子.)

Just a quick reminder: Sentence breaking is actually a pretty complex thing, there's exceptions to the period rule, such as "Mr." or "Dr." There's also a variety of sentence ending punctuation marks. But there's also exceptions to the exception (if the next word is Capitalized and is not a proper noun, then Dr. can end a sentence, for example).
