[Pyparsing] Can I use pyparsing to parse Python?

[Moti Ben-Ari]

Hello,

I am working with a system that has its own simple programming language,
but I would like to construct a preprocessor that will translate a small
subset
of Python into this language. Can I use pyparsing to do this?

I found pythonGrammarParsing.py which seems that it might help,
but I couldn't find an explanation of how to use the bnfDefs to actually
parse a Python program.

Thanks
Moti
