如何使用regex循环过滤特定字符前后的句子部分

Question

'我想在&；之前提取文本；在“：”和“|”之后使用regex并将其分为speaker和title

“有很多这样的句子，所以我需要写一个循环”

 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

您可以使用这个简单的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)

输出：

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
