I tried to access your harddisk, but it failed :-) Let's use
this:

>class B:

>class C(B):
^^^^
> pass
>class D(C):
^^^^
> pass
>Why B, B, B rather than D, C, B?
C inherits from B, and therefore every instance of C is also an
instance of B.
Likewise, D inherits from C, and therefore every instance of D
is also an instance of C, and is also an instance of B.
