英文:
Regex that matches only numbers in a percentage separated by comma or dot
问题
我使用Python，例如，我有一个字符串如下：
a good 98.15% play 应该匹配9815，
a good 98,15% play 也应该匹配9815，
a good 100% play 应该匹配100
a good 98% play 应该匹配98
我已经尝试使用(?<=\s)\S+(?=\%) 来匹配整个98.15，但是有更多的人使用逗号来分隔小数点，我尝试使用其他正则表达式，但没有任何一个能够满足我的问题。
英文:
I use python, for example, I have a string like this:
a good 98.15% play it should match 9815,
a good 98,15% play it should also match 9815,
a good 100% play it should match 100
a good 98% play it should match 98
I have tried to use (?<=\s)\S+(?=\%) to match the whole 98.15 but there are more people using comma to separate decimal number than I thought and I tried to use other regex but there aren't any I could think of that satisfy my problem.

Remove the . if it is there, and the regex to capture the numbers. I'd remove the . first, then simply (\d+)%
In python, I think its .replace('.', '') to remove the .

我已找到解决方法，我只需使用字符串替换方法将所有逗号替换为点，然后使用我的旧正则表达式(?<=\s)\S+(?=%)，它应该匹配该百分比的数字（例如98.15中的98.15%）。
英文:
I have found the solution, I can just use string replace method to replace all commas with dots, and then use my old regex (?<=\s)\S+(?=\%), it should match the number of that percentage (98.15 as in 98.15%)
