不理解Python中的错误消息: AttributeError：'dict‘对象没有属性'append’

Question

我需要做的事

class Restaurant:
    def __init__(self,
                name, website, cuisine):
        self.name = name
        self.website = website
        self.cuisine = cuisine
    
dominoes = Restaurant("Dominoes", "www.dominoes.co.uk", "pizza")
yosushi = Restaurant("Yo Sushi!", "www.yosushi.co.uk", "sushi")
fiveguys = Restaurant("Five Guys", "www.fiveguys.co.uk" ,"burger")

restaurants = dict()
restaurants["Dominoes"] = dominoes
restaurants["Yo Sushi!"] = yosushi
restaurants["Five Guys"] = fiveguys

in_loop = True

while in_loop:

    print("CS1822 Restaurant DB")

    print("1. Display restaurant list")
    print("2. Add a restaurant")
    print("3. Exit")

    choice = input("Please enter your choice: ")

    if choice == "1":
        for name in restaurants:
            restaurant = restaurants[name]
            print(name, "-", restaurant.website, "-", restaurant.cuisine)
            
    elif choice == "2":
        name = input("Enter restaurant name: ")
        website = input("Enter website: ")
        cuisine = input("Enter cuisine: ")
        x = Restaurant(name, website, cuisine)
        restaurants.append(x)
    
    else:
        print("Goodbye!")
        break

我不明白如何解决错误消息：

运行错误跟踪(最近一次调用)：文件"tester.python3"，第55行，在restaurants.append(x) AttributeError：'dict‘对象中没有属性'append’

我试图添加一个用户输入餐厅和它的特点到餐厅列表。

class Restaurant:
    def __init__(self,
                 name, website, cuisine):
        self.name = name
        self.website = website
        self.cuisine = cuisine


dominoes = Restaurant("Dominoes", "www.dominoes.co.uk", "pizza")
yosushi = Restaurant("Yo Sushi!", "www.yosushi.co.uk", "sushi")
fiveguys = Restaurant("Five Guys", "www.fiveguys.co.uk", "burger")

restaurants = dict()
restaurants["Dominoes"] = dominoes
restaurants["Yo Sushi!"] = yosushi
restaurants["Five Guys"] = fiveguys

in_loop = True

while in_loop:

    print("CS1822 Restaurant DB")

    print("1. Display restaurant list")
    print("2. Add a restaurant")
    print("3. Exit")

    choice = input("Please enter your choice: ")

    if choice == "1":
        for name in restaurants:
            restaurant = restaurants[name]
            print(name, "-", restaurant.website, "-", restaurant.cuisine)

    elif choice == "2":
        name = input("Enter restaurant name: ")
        website = input("Enter website: ")
        cuisine = input("Enter cuisine: ")
        x = Restaurant(name, website, cuisine)
        restaurants[name]=x ### You can't use 'append()', because you are using 'dict' in this code, so for 'dict' you need this string

    else:
        print("Goodbye!")
        break
