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

'我要提取“：”和“ |”之前和之后的文本使用正则表达式并将其分成演讲者和标题。

'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

如果您愿意使用纯字符串函数代替正则表达式：

 string(56) "40.76 -73.984 test 73.984 more test second line -73.984 "

Answer 2

使用正则表达式

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

Answer 3

您可以使用此简单的正则表达式'.[:|].'，

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

请注意最后一个:)
