I want to set up an inheritance hierarchy. The base class will define a string value which should include the class name, but I don't want people who inherit from my class to have to remember to override the value.
If I do this using an instance variable, it's reasonably easy: >>> class Base: ... def __init__(self): ... self.key = 'Key_for_' + self.__class__.__name__ ... def display(self): ... print self.key ... >>> class Inherited(Base): ... pass ... >>> b = Base() >>> i = Inherited() >>> b.display() Key_for_Base >>> i.display() Key_for_Inherited Rather than having the key for every instance, I'd like to use a class variable, but I can't see how I'd make that work (a class variable which is inherited but has a different value in derived classes). I could use a classmethod,but that feels like even more overkill than an instance attribute. Is there a way of doing this via class variables or something, or more relevantly, I guess, what would be the idiomatic way of doing something like this?
