in thread regular expression to extract exception/errors in python code base
I suspect that you're asking the wrong question. Grepping like that you'll miss anything uncaught but raised from standard libraries and code, etc. Suggest for python questions that you post a sufficiently detailed description/example of what you actually want to achieve on python-tutor or python-list (aka comp.lang.python). The correct answer probably involves the traceback module.
