python - what went wrong with my get and set properties? -

please need help. code pycharm , keeps showing me unresolved reference 'model'. parameter 'model' value not used , getter signature should (self). please how around this.

class productobject:     def __init__(self, product, brand, car, model, year):         self.product = product         self.brand = brand         self.car = car         self.model = model         self.year = year      def set_product(self, product):         self.product = product.capitalize()      def get_product(self):         return self.product     product = property(get_product, set_product)      def set_brand(self, brand):         self.brand = brand.title()      def get_brand(self):         return self.brand     brand = property(get_brand, set_brand)      def set_car(self, car):         self.car = car.title()      def get_car(self):         return self.car     car = property(get_car, set_car)      def set_model(self):         self.model = model.title()      def get_model(self, model):         return self.model     model = property(get_model, set_model)      def set_year(self):         self.year = year.int()      def get_year(self, year):         return self.year     year = property(get_year, set_year) 

you need change parameters of methods. method needs self , set method need self , model parameter.

def set_model(self, model):     self.model = model.title()  def get_model(self):     return self.model 

edit inheriting class:

class yoursubclass(productobject):     #code of subclass inherit productobject class 

module: if want create module should check module structure nothing more classes init.py file. can import classes normal import statements. here link info init.py file: init.py structure
