Global Dictionary Class

Question

For a Django-Server I use several custom Error-Codes, error-titles and descriptions, possibly other fields might follow.

I'm using right now a basic global dictionary.

errordict = {'512':
    {
        'errorno': 512,
        'errordescr': "Database Down",
        'toDo': "Restart the database, Server: "+serveradr
    },
'513' : ....
}

And in the code something like:

def handleError(s_err):
   curerr=errordict[s_err]
   logging.error("Error "+s_err+" occurred: "+curerr['errordescr'])

The usage looks like this:

   try:
      findEntry(s_id)
   except NoSuchEntryEx as nsee:
      s_err="513"
      handleError(s_err)
      return HttpResponse(render_to_string('error.html', {                
                'errorno':  s_err,
                'errordescr': mark_safe(str(nsee)
                                        + const.OUTPUT_NEWLINE),                
                'toDo': errordict[s_err]['toDo']
            }))

I'm not happy with that and would rather define its own class - which would from the current perspective would just consist of this single, growing dict-object, which does not seem a great idea either.

It's of course a constant, every change there is hard-coded.
