我想在EG之后选择每个单词：字符：，以便我可以将例如：字符：在每个选择后面

字符： mori_calliope 字符： takanashi_kiara chararcter： takanashi_kiara_（phoenix）

我得到的最接近的东西是，我得到

(?<=(\w*):\s*\S*\s.*)(?<=\s)(?=\S)

的是正常工作的，但是当单身时它会破裂例如：字符：某物或当它空的时，

如果有人会帮助我，我真的很感激

I want to select every word after eg:character: so i can put eg:character: behind every selection,

character:mori_calliope character:takanashi_kiara chararcter:takanashi_kiara_(phoenix)

the closest thing i got is

(?<=(\w*):\s*\S*\s.*)(?<=\s)(?=\S)

which works properly but it breaks when there is a single entry on eg:character: something or when its empty

i would be really thankfull if someone would help

您应该安装 pypi regex module 并使用

regex.sub(r'(?<=(\w+):.*)(?<=\s)(?=\S)', r'\1:', text)
# or
# regex.sub(r'(?<=(\w+:).*)(?<=\s)(?=\S)', r'\1', text)

请参见 Regex Demo 。
详细信息：

（？其次是： char，然后除了尽可能多的挂断字符以外的任何零或更多字符？
（与非白人char。

See the Python demo ：

import regex
text = "copyright: hololive hololive_english\ncharacter: mori_calliope takanashi_kiara takanashi_kiara_(phoenix)\nartist: xu_chin-wen\nspecies:\nmeta: web"
print( regex.sub(r'(?<=(\w+):.*)(?<=\s)(?=\S)', r'\1:', text) )

输出：

copyright: copyright:hololive copyright:hololive_english
character: character:mori_calliope character:takanashi_kiara character:takanashi_kiara_(phoenix)
artist: artist:xu_chin-wen
species:
meta: meta:web

You should install PyPi regex module and use

regex.sub(r'(?<=(\w+):.*)(?<=\s)(?=\S)', r'\1:', text)
# or
# regex.sub(r'(?<=(\w+:).*)(?<=\s)(?=\S)', r'\1', text)

See the regex demo.
Details:

(?<=(\w+):.*) - a positive lookbehind that matches a location that is immediately preceded with any word (captured into Group 1) followed by a : char and then any zero or more chars other than line break chars as many as possible
(?<=\s)` - a positive lookbehind that matches a location that is immediately preceded with a whitespace char
(?=\S) - a positive lookahead that matches a location that is immediately followed with a non-whitespace char.

See the Python demo:

import regex
text = "copyright: hololive hololive_english\ncharacter: mori_calliope takanashi_kiara takanashi_kiara_(phoenix)\nartist: xu_chin-wen\nspecies:\nmeta: web"
print( regex.sub(r'(?<=(\w+):.*)(?<=\s)(?=\S)', r'\1:', text) )

Output:

copyright: copyright:hololive copyright:hololive_english
character: character:mori_calliope character:takanashi_kiara character:takanashi_kiara_(phoenix)
artist: artist:xu_chin-wen
species:
meta: meta:web
