python - 在带有“说”这个词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，我正在尝试在包含“他说”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，我可以非常接近，但并不完全正确：

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

结果是：

>>> 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加上了报价，但在第二个实例中放置得太早了。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，因为它看到了结尾的句点one should not.。您真正想要的是仅引用上一时期。因此，请确保在匹配的括号中不包含句点，如下所示：

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

对于句子中带有句点的事物，这将失败，"Dr. Seuss likes to eat, she said"但这是另一个问题。
