Python Regex not returning

I have a function that should return a certain number from a mysql table. The number is filtered out of the string using regex like so: ^\((\d*),\)$. The original string is (36,) and the regex should change it to this: 36. But i still get (36,)!

class db:
    con = mysql.connect()
    cur = con.cursor()

def fo(self, query):
    self.cur.execute(query)
    return re.search('^\((\d*),\)$', 
    str(self.cur.fetchone())).group(0)

and further on I call the function:

return db().fo('SELECT id FROM `GIP-Schema`.user WHERE name = \'{0}\''.format(name))
