Also see the Python ParserSig @ http://www.python.org/sigs/parser-sig/ to discuss and select a standard parser generator for Python.
For faster performance, one may use other parser generator systems and plug them in as modules.
For example:
["ANTLR"] (http://www.antlr.org/) generates C++ output (an older version with C output also available)
["Spirit"] (http://spirit.sourceforge.net/) framework for writing EBNF as C++ code
FlexBisonModule (http://www.cs.utexas.edu/users/mcguire/software/fbmodule/)
[http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&selm=61g0ff%2439g%241%40vishnu.jussieu.fr cocktail compiler tools] approach
Example of such usage is SeeGramWrap available from Edward C. Jones [http://members.tripod.com/~edcjones/pycode.html Python page], which is a heavily revised and upgraded version of the ANTLR C parser that is in [http://members.tripod.com/~edcjones/cgram.tar.gz cgram]. The lastest verson has been refactored to move some of the complexity from ANTLR to Python.
