Solve the following python programming problem given the following code:
def __get__(self, instance, model) : 
    if instance : 
        def conditional_setter(* prepared_conditional, **unprepared_conditionals) : 
            if (len (prepared_conditional) > 0) : 
                conditionals = prepared_conditional [0] 
else : 
                conditionals = instance.objects.iff (** unprepared_conditionals)._conditional 
instance._conditional = conditionals 
            return instance 
return self 
qs = model.__queryset__ (model) 
    def conditional_setter(**unprepared_conditionals) : 
        conditionals = model.objects.iff (** unprepared_conditionals)._conditional 
        qs._conditional = conditionals 
        return qs 
return conditional_setter
