替换 2 个字符串 python 之间的所有文本 [英] Replace all text between 2 strings python

问题描述

假设我有:

a = r''' 示例这是一个很烦人的字符串占用多行和 h@s//种{s} 愚蠢的符号好的字符串'''

我需要一种在This"和ok"之间进行替换(或只是删除)和文本的方法，以便当我调用它时，a now 等于:

a = "示例字符串"

我找不到任何似乎有效的通配符.非常感谢任何帮助.

解决方案

你需要正则表达式:

<预><代码>>>>进口重新>>>re.sub('\nThis.*?ok','',a, flags=re.DOTALL)'示例字符串'

Lets say I have:

a = r''' Example
This is a very annoying string
that takes up multiple lines
and h@s a// kind{s} of stupid symbols in it
ok String'''

I need a way to do a replace(or just delete) and text in between "This" and "ok" so that when I call it, a now equals:

a = "Example String"

I can't find any wildcards that seem to work. Any help is much appreciated.

解决方案

You need Regular Expression:

>>> import re
>>> re.sub('\nThis.*?ok','',a, flags=re.DOTALL)
' Example String'
