问题描述

python搜索字符x"下一步删除这个字符x"+字符x"-1在字符串中的位置

python search character "x" next step delete this character "x" + character "x" -1 postion in string

Example x="1. 520 2. 529"

我要在 x 中搜索."并删除."和."前的数字最后我希望它看起来像 x="520 529"

I am going to search in x "." and delete "." and number before "." in end I want it look like x=" 520 529"

在我创建这个主题之前，我只发现用一个字符替换一个字符

Before I created this topic I only find replace one character for one character

推荐答案

import re

re.sub(r'(.\.)', '', a)

其中 a 是您要替换的字符串.

Where a is the string you want to replace in.
