[Tutor] Inner Class access to outer class attributes?

Recall that in Python variables are simply references to objects. 
So every sublocation has a reference to the same groupLocation object

No, just change the groupLocation and the change will show 
up in every sublocation.

FWIW this is how virtually all GUI frameworks operate, 
the top level window is passed as a parent to each widget.

The problem appears to be that you need to read a bit more 
about Pythons handling of variable names and objects. :-)
