You might want to add a summary function, like so:

   def summary(self):
      collector = {}
      countall, spaceall = (0,0)
      for thing in self.contents:
          name = thing.code
          cube = thing.cube
          count, sofar = collector.get(name, (0,0) )
          collector[name] = count+1, sofar + cube
          countall, spaceall = countall+1, spaceall+cube
      result = collector.items()
      result.sort()
      print "Item\t\tVolume"
      for name, (manifold, space) in result:
          print "%s(%d)\t\t%d" % (name, manifold, space)
      print "%d Objects, total volume=%d" % (countall, spaceall)

And please, next time submit tested code.
Yours had about three bugs.
