I am certainly biased, but I think that Parsing is the greatest thing
since sliced bread, at least as far as Python-based parser generators
go. Parsing is an LR(1) parser generator, and it includes both CFSM
("LR") and GLR parser drivers.


Parsing: http://www.canonware.com/download/Parsing/Parsing.py

Don't let the simplicity of the example fool you into thinking that
Parsing is a toy -- I have used it for some very large grammars, with
great success.
