simplified Python parsing question

Another possibility is to use the ast module of python: http://docs.python.org/library/ast.html

The only problem with that module, is that everything you parse must be correct, otherwise it throws an exception, I don't know if that's a problem for your project?

thanks, I'll take a look.

yeah the problem is also little more complicated than simple parsing of Python 
code. For example, one example (from the white paper)

*meat space blowback = Friends and family [well-meaning attempt]

*could that be parsed by the tools you mention? I suspect not but this is what I 
need to generate using speech recognition because it's easily spoken. A more 
complex example might be something like

new base = OS path-base name (old path)

or

if OS base exists (current path): new base name = OS path base name(current path)

What's particularly cute here is that using the translation technique I can 
actually describe the full object method path with a minimum of speaking 
overhead. Python is great. :-)

But the questions remain, will these tools are stuff like this?
