I didn't get what is meant by hiding?
You can override the function/method of base class in sub class.
In that method, you can modify the behaviour for subclass or 
raise an exception or simply include 'pass'.

Anyway, deleting any property of a class in it's subclasses clearly violates the liksov substitution principle.
