Thank you very much for your reply.

I guess I should have been clearer. I meant reading the inherited 
*default* value from the parent class. Given the same code (repeated 
below), I see:

 >>> q = R()
 >>> print q.x
0
 >>> e = S()
 >>> print e.x
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "<stdin>", line 5, in getx
AttributeError: 'S' object has no attribute '_R__x'
 >>>

Can e *not* inherit to the default value? Or is there a way to call the 
__init__ method for R's superclass (so that 'x' in initialized?).
