DEBUG = 1
class superclass:
def __init__(self):
self.debug = DEBUG
self.a = 1
self.b = 2
if self.debug:
self.dodebug()
def dodebug(self):
print self.a
print self.b
class subclass(superclass):
def __init__(self):
superclass.__init__(self)
self.debug = DEBUG
self.a = 2
self.b = 4
if self.debug:
superclass.dodebug(self)
def dodebug(self):
pass
Will this work for you?
