在python中查找并删除以特定子字符串开头和结尾的字符串 [英] Find and remove a string starting and ending with a specific substring in python

问题描述

我有一个类似于 "dasdasdsafs[image : image name : image]vvfd gvdfvg dfvgd" 的字符串.从这个字符串中，我想删除从 [image : 开始并以 : image] 结尾的部分.我尝试使用以下代码找到子字符串"-

result = re.search('%s(.*)%s' % (start, end), st).group(1)

但它没有给我所需的结果.帮我找到从字符串中删除子字符串的正确方法.

解决方案

您可以使用 re.sub :

<预><代码>>>>s='dasdasdsafs[图像:图像名称:图像]vvfd gvdfvg dfvgd'>>>re.sub(r'\[image.+image\]','',s)'dasdasdsafsvvfd gvdfvg dfvgd'

I have a string similar to "dasdasdsafs[image : image name : image]vvfd gvdfvg dfvgd". From this string, I want to remove the part which stars from [image : and ends at : image] . I tried to find the 'sub-string' using following code-

result = re.search('%s(.*)%s' % (start, end), st).group(1)

but it doesn't give me the required result. Help me to find the correct way to remove the sub-string from the string.

解决方案

You can use re.sub :

>>> s='dasdasdsafs[image : image name : image]vvfd gvdfvg dfvgd'
>>> re.sub(r'\[image.+image\]','',s)
'dasdasdsafsvvfd gvdfvg dfvgd'
