python - 如何在python中的字符串中的每个字符后添加换行符，如“.[xxx]”

Question

我有以下字符串：

It reported the proportion of the edits made from America was 51% for the Wikipedia, and 25% for the simple Wikipedia.[142] The Wikimedia Foundation hopes to increase the number in the Global South to 37% by 2015.[143]

我正在尝试.[xxx] 用.[xxx] \n;替换每个这样的字符

x 是这里的数字

我正在从不同的茎溢出答案中获得帮助；其中之一是：

Python 在字符“X”之后在字符串中插入换行符

正则表达式：匹配句号和python中的一个单词

import re
str = "It reported the proportion of the edits made from America was 51% 
for the Wikipedia, and 25% for the simple Wikipedia.[142] The Wikimedia 
Foundation hopes to increase the number in the Global South to 37% by 
2015.[143] "
x = re.sub("\.\[[0-9]{2,5}\]\s", "\.\[[0-9]{2,5}\]\s\n",str)
print(x)

我期望以下输出：

It reported the proportion of the edits made from America was 51% for the Wikipedia, and 25% for the simple Wikipedia.[142]                          
The Wikimedia Foundation hopes to increase the number in the Global South to 37% by 2015.[143]”

但我得到：

It reported the proportion of the edits made from America was 51% for the Wikipedia, and 25% for the simple Wikipedia\\.\[[0-9]{2,5}\]\s   The Wikimedia Foundation hopes to increase the number in the Global South to 37% by 2015\\.\[[0-9]{2,5}\]\s

您可能希望在re.sub. 您也不需要转义替换字符串（regex101）：

import re
s = '''It reported the proportion of the edits made from America was 51% for the Wikipedia, and 25% for the simple Wikipedia.[142] The Wikimedia Foundation hopes to increase the number in the Global South to 37% by 2015.[143] '''
x = re.sub(r'\.\[([0-9]{2,5})\]\s', r'.[\1] \n', s)
print(x)

印刷：

It reported the proportion of the edits made from America was 51% for the Wikipedia, and 25% for the simple Wikipedia.[142] 
The Wikimedia Foundation hopes to increase the number in the Global South to 37% by 2015.[143]
