Incomplete sentence? Do I sense a master-class in the offing?

Surely though, if an attribute is part of a SuperClass then it will 
'appear' in the SubClass. If SubClass.x overrides SuperClass.x (or x() ) 
then attribute-x still appears, even if it contains different data, a 
different type, or different code?

Granted that SuperClass.x is 'invisible' if SubClass.x has been defined, 
but even so, instead of self.x can't we still access SuperClass.x?
(I can't think of a time when I've tried, but...)

Is there another case when a super class's attribute will not be inherited.

(again: excluding slots or other sleigh-of-hand)

So sad. His parents had such high hopes for him; yet now he is condemned 
to join us in the asylum known as programming...
