Python 正则表达式字符串替换题

Question

I have the text "level": NumberInt(3) and I want to replace it with "level": 3 . How do I do it using replace? I've tried this so far so it's not working

o.level = str(s.replace(r'[^0-9]', ''))
print(o.level)

But I keep getting "level": NumberInt(3)

Answer 1

import re
s = '"level": NumberInt(3)'
re.sub(r'NumberInt\((\d+)\)', r'\1', s)

'"level": 3'
