одна из моих переменных def застряла на том же значении

Question

Я новичок в python и на этом веб-сайте* Мне сложно понять, почему я получаю такое же значение из моей функции Car.name

class Car:
    def __init__(self, name, price):
        Car.name = name
        Car.price = price

Я сохранил данные об автомобилях в классе

Lamborghini_Centenario = Car("Lamborghini Centenario", 2500000)
Rolls_Royce_Sweptail = Car("Roll's-Royce Sweptail", 12800000)
McLarenP1LM = Car("McLaren P1 LM", 3600000)
Koenigsigg = Car("Koenigsigg CCXR Trevita", 4800000)
Lykan_Hypersport = Car("Lykan Hypersport", 3400000)
Lamborghini_Veneno_Roadster = Car("Lamborghini Veneno Roadster", 4500000)
Aston_Martin_Valkyrie = Car("Aston Martin Valkyrie", 3200000)
Bugatti_Chiron = Car("Bugatti Chiron", 2700000)
Pagani_Huayra_BC = Car("Pagani Huayra BC", 2800000)
Ferrari_Sergio = Car("Ferrari Pininfarina\n      Sergio", 3000000) <--.
                                                                      |
#But when I try to get the name of a random car                       |
#Here is the code I used vvv (Carlist is not shown here)              |                    
#b = random.choice(carlist)                                           | ignore arrow not part of 
#b.name                                                               | code(sorry couldn't come
#it only gets the name from the bottom of the car data area.  --------+ up with a name)
#I have switched it up and have only been getting the bottom value
#it might be due to the turtle module .mainloop() function

вот весь сценарийЗаранее спасибо

Answer 1

Вам нужно установить атрибуты для объекта, а не для класса.

class Car:
    def __init__(self, name, price):
        self.name = name
        self.price = price

Car.name установит name атрибут на Carкласс. Вы сможете получить доступ кname атрибут из Car class напрямую без использования таких объектов, как Car.name.

Настройка Car.name каждый раз обновляет name атрибут Car класс, и он обновляется каждый раз, когда вы создаете Carобъект. Следовательно, он сохраняет только последнее значение.
