python - 在带有单词 "said"的句子周围添加引号

Question

好的正则表达式大师，我有一个很长的文本，我试图在包含单词“he said”和类似变体的句子中添加引号。

例如:

s = 'This should have no quotes. This one should he said. But this one should not. Neither should this. But this one should she said.'

应该导致:

This should have no quotes. "This one should," he said. But this one should not. Neither should this. "But this one should," she said.

到目前为止，我可以很接近，但不太正确:

>>> import re
>>> m = re.sub(r'\.\W(.*?) (he|she|it) said.', r'. "\1," \2 said.', s)

结果:

>>> print m
This should have no quotes. "This one should," he said. But this one should not. "Neither should this. But this one should," she said.

如您所见，它在第一个实例周围正确地放置了引号，但对第二个实例放置得太早了。任何帮助表示赞赏!

评论中指出了一些不同的有效情况，但为了解决您面临的问题:

它引用了整个句子，因为它看到 one should not. 末尾的句点.您真正想要的是只引用最后 时期。因此，在匹配的括号中确保不要包含句点，如下所示:

m = re.sub(r'\.\W([^\.]*?) (he|she|it) said.', r'. "\1," \2 said.', s)

对于像 "Dr. Seuss likes to eat, she said" 这样的句子中带有句点的东西，这将失败但这是另一个问题。
