Newbie Need Help On Regex!

Hey guys! I am new to learning regex in python and I'm wondering how do I use regex in python to store the integers(positive and negative) i want into a list! For e.g. This is the data in a list. [u'\x1b[0m[\x1b[1m\x1b[0m\xbb\x1b[0m\x1b[36m]\x1b[0m (A=-5,B=5)', u'\x1b[0m[\x1b[1m\x1b[0m
