Parsing Python question (newbie)

[Loki Patrick]

Hi, I've been toying with writing a parser (in Python) for Python.
Has someone already done this?

A .py to .pyc compiler would be nice. I know there is some kind
of parser generator written in C bundled with Python, but
does it produce recursive descent parsers, or table driven?
I'd prefer recursive descent for reasons of readability.

Any help would be appreciated.
