Grammar parsing

[Paolo Pantaleo]

Hi,

How can I write a pareser for a certain gramamr? I found PyPy that
does it, is thare any other tool? Maybe something built-in the python
interpreter?

Thnx
PAolo

The standard library gets you partway there, with 'shlex':

The cheeseshop knows of 'pyparsing':

Thnx everybody for the help,

I finished using pyparsing actually, that is very handy and nice to use.
