I'm not sure  I fully understand you, but something like the following
seems common in Python:

Module somelib:

   class Error(Exception):
	pass

   def somefunc():
       '''does something
          beware, could raise Error
       '''
       raise Error


Module MyProg:

   import somelib

   try:
	somelib.somefunc()
   except somelib.Error:
        'do something about it'
