使用正则表达式提取包含括号和百分比符号的字符串的特定部分

Question

I have the string "6324.13(86.36%)" , and I'd like to extract out 86.36 only. I used the following regex, but the output still comes with the bracket and percentage character.

re.search('\((.*?)\)',s).group(0) -> (86.36%)

I used the following instead, but it returns an array containing a string without the brackets. However, I still can't remove the percentage character.

re.findall('\((.*?)\)',s) -> ['86.36%']

I'm just not sure how to modify the regex to remove that % as well. I know I can use string slicing to remove the last character, but I just want to resolve it within the regex expression itself.

Answer 1

Add a percentage sign to the regular expression, so that it's omitted from the capture group:

import re
s = "6324.13(86.36%)"
result = re.findall('\((.*?)%\)',s)
print(result) # Prints ['86.36']
