每个字符之后如何添加newline”.[xxx]“在python中的字符串中

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]

我试图用 .[xxx] n替换每个字符lik this .[xxx];

x在这里是数字

我正在从不同的茎溢出答案中获得帮助；一个是：

python在字符的字符串中插入一个线断裂，" x＆quot"

REGEX：匹配fullstop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}]sn",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]”

但是我得到了：

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

Answer 1

您可以使用

(.[[^][]*])s*

并将其替换为1n，请参见Regex101.com上的上的演示。

---

这是

(
    .[   # ".[" literally
    [^][]* # neither "[" nor "]" 0+ times
    ]     # "]" literally
)s*       # consume whitespaces, eventually

Answer 2

使用findall((识别匹配模式的列表。然后，您可以用原始字符串 ' n'

Answer 3

您可能想在re.sub中使用捕获的组和反向引用。您也无需逃脱替换字符串( 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)

打印：

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]
