如何使用正则表达式循环在特定字符之前和之后过滤句子的一部分

Question

'I want to extract the text before & after ":" and "|" using regex and seperate it into speaker and title.

'There are many such sentences so I need to write a loop'

 text1='If I controlled the internet | Rives '
 text2='Life at 30,000 feet | Richard Brandson'
 text3='larry brilliant : A surprising idea for "solving" climate change'

Answer 1

If you are willing to use plain string functions instead of regex:

if '|' in text:
    title, speaker = text.split('|', 1)
elif ':' in text:
    speaker, title = text.split(':', 1)

Answer 2

使用正则表达式

re.compile('[\s]*[|:][\s]*').split(text)

Answer 3

you can use this simple regex '.[:|].' ,

import re
text1='If I controlled the internet | Rives '
text2='Life at 30,000 feet | Richard Brandson'
text3='larry brilliant : A surprising idea for "solving" climate change'

text = (text1, text2, text3)

for item in text:
    title, speaker = re.split('.[:|].', item)
    print('title:', title, ' - Speaker:', speaker)

output:

title: If I controlled the internet  - Speaker: Rives 
title: Life at 30,000 feet  - Speaker: Richard Brandson
title: larry brilliant  - Speaker: A surprising idea for "solving" climate change

note the last one :)
