I seriously doubt that. I guess you didn't show us the real code. But 
there is no way that an instance variable can be accessed on type-level 
in a derived class (or from anywhere, for that matter). So I presume you 
have some misconceptions about pythons OO-model that will sooner or 
later bite you - for example if you want to have several Front-objects.
