How can I access a class attribute (or class method)
from within the class in a virtual way, so that in a derived class
the the member of the derived class will be accessed?
Here is a non-working example to explain what I mean:
class A( object ):
hello = None
def __init__( self ):
def _setHello( x ):
A.hello = x * x # How can this assignment be made virtual?
setHello = staticmethod( _setHello )
class B( A ):
hello = None # Without this statement B.hello will be A.hello!
B.setHello( 10 ) # Here B.hello shall be set
print A.hello, B.hello # (but of course is not).
Since python is an oo language and all members ar virtual, there should be
a simple way to achieve that.
Who knows how?
