Here is a cheap, nasty and insecure solution
>>> a='("." ".." "cdslib_cleanup.py" "cadence.py" "cdsinit_cdsenv_cleanup.py")'
>>> eval(a.replace('" "', '", "').replace('" (', '", (').replace(') "', '), "'))
('.', '..', 'cdslib_cleanup.py', 'cadence.py', 'cdsinit_cdsenv_cleanup.py')
>>> b='("." ("cadence.py" "foo_cleanup.py") "cdslib_cleanup.py" "cadence.py"
>>> "cdsinit_cdsenv_cleanup.py")'
>>> eval(b.replace('" "', '", "').replace('" (', '", (').replace(') "', '), "'))
('.', ('cadence.py', 'foo_cleanup.py'), 'cdslib_cleanup.py', 'cadence.py',
'cdsinit_cdsenv_cleanup.py')
>>>
It made tuples rather than lists but I expect that won't matter.
Someone normally chimes in with pyparsing at this point...
