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.
