在不删除分隔符的情况下拆分正则表达式 [英] Splitting on regex without removing delimiters

问题描述

所以，我想把这段文字分成句子.

So, I would like to split this text into sentences.

s = "You! Are you Tom? I am Danny."

所以我得到:

["You!", "Are you Tom?", "I am Danny."]

也就是说，我想通过正则表达式 '[.!\?]' 拆分文本而不删除分隔符.在python中实现这一点的最pythonic方法是什么?

That is I want to split the text by the regex '[.!\?]' without removing the delimiters. What is the most pythonic way to achieve this in python?

我知道这些问题:

JS string.split() 不删除分隔符

Python split() 不删除分隔符

但我的问题有各种分隔符(.?!)，这使问题复杂化.

But my problem has various delimiters (.?!) which complicates the problem.

推荐答案

您可以使用 re.findall 和正则表达式 .*?[.!\?];惰性量词 *? 确保每个模式匹配到您想要匹配的特定分隔符:

You can use re.findall with regex .*?[.!\?]; the lazy quantifier *? makes sure each pattern matches up to the specific delimiter you want to match on:

import re

s = """You! Are you Tom? I am Danny."""
re.findall('.*?[.!\?]', s)
# ['You!', ' Are you Tom?', ' I am Danny.']
