I think I am very close the return line is tripping me up.  (this is
the first list that I have tried to program in python)

return (s.group[1], s.group[2])

Traceback (most recent call last):
  File "C:\Python24\Lib\site-packages\boa-constructor\test of
snake\test_of_csoundroutines_list.py", line 5, in ?
    v = csoundroutines.csdInstrumentList('bay-at-night.csd')
  File "C:\Python24\Lib\site-packages\boa-constructor\test of
snake\csoundroutines.py", line 43, in csdInstrumentList
    return (s.group[1], s.group[2])
TypeError: unsubscriptable object
