Hello, I was having some trouble understanding decorators and inheritance and all that. This is what I was trying to do:
# untested class A(object): def _protector_decorator(fcn): def newfcn(self, *args, **kwargs): return fcn(self, *args, **kwargs) return newfcn @_protector_decorator def my_method(self, *args, **kwargs): """ do something here """ class B(A): def _protector_decorator(fcn): def newfcn(self, *args, **kwargs): raise MyException('I do not want B to be able to access the protected functions') return newfcn The goal of all that was to be able to change the behavior of my_method inside class B simply by redefining the decorator. Basically, what I want is B.my_method() to be decorated by B._protector_decorator, but in the code I'm running it's decorated by A._protector_decorator. I presume this is because once the decorator is applied to my_method in class A, A.my_method is immediately bound to the new, 'decorated' function, which is subsequently inherited (and not decorated, obviously), by B. Am I correct here? My workaround was to simply copy the method from class A to class B, after which B._protector_decorator decorated the methods in B. While this doesn't make the use of decorators completely pointless (the decorators actually do something in each class, it's just different), it does add a bunch of code duplication which I was at one point hopeful to avoid. I'm still stumbling around with decorators a little, but this exercise has made them a lot clearer to me. Thanks! Jason
