You probably meant
   def title( self, title=None ):
     if title == None:
        return self._title
     else:
        self._title = title

or every read access would clear the attribute.

1. Some people dislike methods that do very different things depending 
on the parameters. These are difficult to explain. Though in your case, 
one central explanation and links from all the methods should be enough.

2. None is often a useful value, so perhaps you should use a module 
local variable like _GetValue (actual value is irrelevant)
     def title (self, title = _GetValue):
