I understand that you are doing this as a learning exercise. Still, I would recommend you to have a look at the shlex module in the standard library and to pyparsing. Looking at their source code should should give you some idea. BTW, since you are familiar with Lisp, I would recommend you IPython for a better interactive experience.
