如何拆分字符串以保留标点符号？ （Python）

Question

考虑到结果中的标点符号，如何在python中拆分字符串？

以下代码：

s = "Hello, my name is Robert."
s_splitted = s.split()

将给出输出：

["Hello,","my","name","is","Robert."]

如何获得以下结果？

["Hello",",","my","name","is","Robert","."]

Answer 1

正则表达式可以处理此问题。

import re

s = "Hello, my name is Robert."
s_splitted = [part for part in re.split(r'\b|\s', s) if part != '']
# ['Hello', ',', 'my', 'name', 'is', 'Robert']

this回答您的问题吗？

所以在您的情况下：

import re

s = "Hello, my name is Robert."
items = re.findall(r"[\w']+|[.,!?;]", s)
