__getattr__ не создает атрибут, выдает ошибку KeyError

class Mazda:
    
    wheel = "r-17"
    color = "black"
    engine = 2.0
    doors = 4
    gear_box = "manual"   
    
    def __getattribute__(self, value):
        print ("__getattribute__")
        if value == "color":
            return "Отвали"
        else:
            return object.__getattribute__ (self, value)
    
    def __getattr__ (self, value):
        print ("__getattr__")
        self.__dict__[value] == 0
        return 0
    
a = Mazda ()
print (a.lights)

В консоли получаю:

Traceback (most recent call last):

    print (a.lights)
