Python 在创建列表和调用变量时迷失方向

我目前正在尝试创建一个菜单来为餐厅选择食物，但不知道如何正确显示菜单。我目前对它应该如何工作的非常粗略的想法如下：

name = int(input ('Welcome to Dinos Cupcakes, enter your name to continue  '))

cc_list = [
            ['1. Chocolate-dipped Maple Puff ($3.50 each)', 1, 3.50],
            ['2. Strawberry Twizzler ($2.25 each)', 1, 2.25],
            ['3. Vanilla Chai Strudel ($4.05 each) ', 1, 4.05],
            ['4. Honey-drizzled Lemon Dutchie ($1.99)', 1, 1.99]]
print cc_list

while #Selection does not equal 1-4 repeat list

quantity = int(input('How many would you like to purchase of this variety  '))

new_quantity = quantity * #Dougnut selection



print (name, 'here is your receipt:'):

我希望最终打印出如下内容：

name = int(input ('Welcome to Dinos Cupcakes, enter your name to continue  '))

cc_list = [
            ['1. Chocolate-dipped Maple Puff ($3.50 each)', 1, 3.50],
            ['2. Strawberry Twizzler ($2.25 each)', 1, 2.25],
            ['3. Vanilla Chai Strudel ($4.05 each) ', 1, 4.05],
            ['4. Honey-drizzled Lemon Dutchie ($1.99)', 1, 1.99]]
print cc_list

while #Selection does not equal 1-4 repeat list

quantity = int(input('How many would you like to purchase of this variety  '))

new_quantity = quantity * #Dougnut selection



print (name, 'here is your receipt:'):

姓名这是您的收据：

-------------------------------#巧克力浸枫叶泡芙-------------------------------

总成本：$

谢谢，祝你今天愉快

给你，这是一个“原始”的，请使用Python3.x

name = input ('Welcome to Dinos Cupcakes, enter your name to continue  ')

cc_list = [
            ['1. Chocolate-dipped Maple Puff ($3.50 each)', 1, 3.50],

            ['3. Vanilla Chai Strudel ($4.05 each) ', 1, 4.05],
            ['4. Honey-drizzled Lemon Dutchie ($1.99)', 1, 1.99]]
print(cc_list)

selection = int(input("Please select 1-4"))
while selection not in [1,2,3,4]:
    selection = int(input("Please select 1-4"))

quantity = int(input('How many would you like to purchase of this variety  '))

total_cost = quantity * cc_list[selection][2]

print(f'{name}, here is your receipt:')
print(f'------------------------------- # {cc_list[selection][0]} -------------------------------')
print(f'Total cost: ${total_cost}')
print('Thank you, have a nice day!')

CMD输出：

没有为你做任何事。下面的内容应该足以满足您的需要。请记住，您的cc_列表实际上是列表中的一个列表。要引用元素，您需要引用选择（1,2,3,4），然后引用列表中的元素（0,1,2）

这将允许您提取用户为获取字符串所做的选择以及价格。有了这个，你应该能够找出如何给他们一个总数，并格式化你的输出

name = input('Welcome to Dinos Cupcakes, enter your name to continue  ')
cc_list = [
            ['1. Chocolate-dipped Maple Puff ($3.50 each)', 1, 3.50],
            ['2. Strawberry Twizzler ($2.25 each)', 1, 2.25],
            ['3. Vanilla Chai Strudel ($4.05 each) ', 1, 4.05],
            ['4. Honey-drizzled Lemon Dutchie ($1.99)', 1, 1.99]]
print(cc_list)


selct = int(input("Enter a number"))

order = cc_list[selct+1][0]
cost =str(cc_list[selct+1][2])




print(name + " your stuff")
print("The total cost is " + cost)

for x in range(len(cc_list)):
    print(cc_list[x])

selection = int(input("Please select 1-4 : "))
