  1. with the final version of the code, that use the @property decorator, I still can see the internal variable product.__price in the list, also if hidden by two underscores:

  2. if I comment the @price.setter section, I get an error because the constructor can’t set the value of the price:

you did it wrong

def __init__(self,price):
    #self.price = price    
    self.__price = price
