How to create a regex rule in (xxx-number) format?

I have strings like this:

(jack-9) - london
(neil-11) - india

I would like to write a rule that gives the number, how can I do that?
expected output:

9
11

>Solution :

You can use \w+\-(\d+):

>>> import re
>>> s = """(jack-9) - london
... (neil-11) - india"""
>>> re.findall("\w+\-(\d+)", s, re.MULTILINE)
['9', '11']
