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.
