This may help.

This works on Python 2.4:
>>> import shlex
>>> sh = shlex.shlex('$(which sh)')
>>> sh.get_token()
'$'
>>> sh.get_token()
'('
>>> sh.get_token()
'which'
>>> sh.get_token()
'sh'
>>> sh.get_token()
')'
>>> sh.get_token()
etc...
Python 2.2 and maybe lower:
>>> import shlex
>>> import StringIO
>>> s = StringIO.StringIO('$(which sh)')
>>> sh = shlex.shlex(s)
>>> sh.get_token()
'$'
>>> sh.get_token()
'('
>>> sh.get_token()
'which'
>>> sh.get_token()
'sh'
>>> sh.get_token()
')'
>>> sh.get_token()
etc...
