python find exception message (with ast?) -


i want compile list of messages program present user, errors (to able quality-check wording). let's assume have own exception class

class myexception( exception ):     pass

and want find programmatically instances 

raise myexception( "this baadly worded message typo." )

is there elegant python way retrieve:

  • the message
  • the line number
  • the (member) function name raises exception?

ideally, work cases like

msg = "my long error message\n" msg += "where explain fit directly raise call" raise myexception( msg )

so want localize python application.

in case have loot @ gettext powerful localization framework, 1 used open-source projects, not python ones.
