Python 试图用正则表达式拆分句子

到目前为止，我发现这个正则表达式在我参与的几乎所有竞赛中都很有效

(?<!\w\.\w.)(?<![A-Z][a-z]\.)(?<=[.?])\s

进入：

不幸的是，它不包括一个案例。 例如，如果我有这样一句话：

C. Daniel, who love cakes, is taking a trip to Nevada. Not gonna lie, i would go as well.

该正则表达式将其拆分为三个子句：

C.
Daniel, who love cakes, is taking a trip to Nevada.
Not gonna lie, i would go as well.

而不是：

C. Daniel, who love cakes, is taking a trip to Nevada.
Not gonna lie, i would go as well.

我们缺少的是这种特殊情况，即当我们找到一个匹配时，它有一个大写字母表，后跟一个点（.），我们不必拆分

我仍然不知道如何正确使用正则表达式，因此如果你能告诉我为什么你的答案会有效，我将非常感谢你可以扩展这个模式，添加一个负lookbehind

（？声明不是大写字符，后面紧跟着一个
）

我想你也可以省略
\w.
后面的点，因为点匹配除换行符以外的任何字符

(?<!\b[A-Z]\.)(?<!\w\.\w)(?<![A-Z][a-z]\.)(?<=[.?])\s

如果您想要基于非正则表达式的解决方案，可以在此处使用nltk

import nltk

txt_1 = "C. Daniel, who love cakes, is taking a trip to Nevada. Not gonna lie, i would go as well."

nltk.sent_tokenize(txt_1)

['C. Daniel, who love cakes, is taking a trip to Nevada.',
 'Not gonna lie, i would go as well.']

txt_2 = "Mr. Daniel, who love cakes, is taking a trip to Nevada. Not gonna lie, i would go as well."
nltk.sent_tokenize(txt_2)

['Mr. Daniel, who love cakes, is taking a trip to Nevada.',
 'Not gonna lie, i would go as well.']

似乎它起作用了！你能告诉我为什么你也放了a\b吗？@costabrava在这种情况下，当字符串以2个大写字符结尾时，它可能会分裂。
(?<!\b[A-Z]\.)(?<!\w\.\w)(?<![A-Z][a-z]\.)(?<=[.?])\s

import nltk

txt_1 = "C. Daniel, who love cakes, is taking a trip to Nevada. Not gonna lie, i would go as well."

nltk.sent_tokenize(txt_1)

['C. Daniel, who love cakes, is taking a trip to Nevada.',
 'Not gonna lie, i would go as well.']

txt_2 = "Mr. Daniel, who love cakes, is taking a trip to Nevada. Not gonna lie, i would go as well."
nltk.sent_tokenize(txt_2)

['Mr. Daniel, who love cakes, is taking a trip to Nevada.',
 'Not gonna lie, i would go as well.']
