Hmm. I'm not (blush) familiar with named tuples. I was thinking
something simple-minded like the following. By all means feel free to do
the pythonic thing though.

import re

rex=re.compile('([^(\s]+)\s*[(]([^)]+)[)]$')

def parse_source(string):
    matches=rex.match(string)
    if matches:
        return (matches.group(1),matches.group(2))
    else:
        return string

def test_parse_source_without():
    assert parse_source('0xffff') == '0xffff'
    
def test_parse_source_with():
    assert parse_source('0xffff (0.8-1)') == ('0xffff','0.8-1')
