Find and remove a string starting and ending with a specific substring in python
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.
你可以使用re.sub ：
>>> s='dasdasdsafs[image : image name : image]vvfd gvdfvg dfvgd'
>>> re.sub(r'[image.+image]','',s)
'dasdasdsafsvvfd gvdfvg dfvgd'
您可能只需要将方括号转义出来，因为这些是正则表达式中的特殊字符（即start = r“ [image：”和end = r“：image ]”）。
这将删除字符串中的所有事件
import re
s = "dasdasdsafs[image : image name : image]vvfd gvdfvg dfvgd"
s = re.sub(r'[image :.*?: image]', r'', s)
