Dynamic objects

[Mark Shewfelt]

Hello,

I have implemented a series of classes representing a Building, its
respective Equipment, and then various Components of that equipment
like so (as you'll be able to tell, I'm a newbie):

class Building:
     equipment = {}
     def AddEquipment( name, data ):
          equipment[ name ] = Equipment( data )

class Equipment:
     components = {}
     def AddComponent( name, data ):
           components[ name ] = Component( data )

class Component:
     data = ""

These classes are used like so:

test = Building()
test.AddEquipment( "equipment 1", data )
test.AddEquipment( "equipment 2", data )
test.equipment["equipment 1"].AddComponent( "component 1", data )
test.equipment["equipment 1"].AddComponent( "component 2", data )
test.equipment["equipment 2"].AddComponent( "component 3", data )

But it appears as though the instance of "equipment 1" has ALL of the
components in its components dictionary. I was hoping that the
test.equipment["equipment 1"].components dictionary would only have
those components that were assigned to "equipment 1".

I have implemented __init__  functions for all of the classes, but all
they do is initialize some data that I haven't shown here.

I think I'm trying to use a C++ way of doing this (without the new
operator) so if anyone would be so kind as to help with the Python way
of doing this sort of thing I will be eternally grateful.

Cheers,
