OK, this seems pretty minimal, yet versatile. It would be nice to be able to patch the traceback, but it turns out that it's fairly hard to do. If you really want to do that, however, go take a look at http://lucumr.pocoo.org/cogitations/2007/06/16/patching-python-tracebacks-part-two/ # Written by Sam Denton <[EMAIL PROTECTED]> # You may use, copy, or distribute this work, # as long as you give credit to the original author. def rewriten_exception(old, f): class Empty(): pass new = Empty() new.__class__ = old.__class__ new.__dict__ = old.__dict__.copy() new.__str__ = f return new def test(code): try: code() except Exception, e: raise rewriten_exception(e, lambda: str(e) + ", sorry!") test(lambda: unicode('\xe4')) test(lambda: 1/0) -- http://mail.python.org/mailman/listinfo/python-list
