Python提取包含单词的句子

问题描述

In [3]: re.findall(r"([^.]*?apple[^.]*\.)",txt)                                                                                                                             
Out[4]: ['I like to eat apple.', " Let's go buy some apples."]

解决方法

我正在尝试从文本中提取所有包含指定单词的句子。

txt="I like to eat apple. Me too. Let's go buy some apples."
txt = "." + txt
re.findall(r"\."+".+"+"apple"+".+"+"\.",txt)

但它正在回报我：

[".I like to eat apple. Me too. Let's go buy some apples."]

代替 ：

[".I like to eat apple.,"Let's go buy some apples."]

有什么帮助吗？
