[Zope] Equivalent to exc_info in python script

Hello All, I'd like to use examine the error type and value when an exception is thrown in a python script, equivalent to: err_type = sys.exc_info()[0] err_value = sys.exc_info()[1] But sys.exc_info can't be accessed from a script. I'm sure there must be an easy way to get at the error value and type, but I can't find it. Can anyone help? Thanks, Jim Gallacher
