打印时不断加括号和引号

Question

我正在尝试创建一个制作购物清单然后允许用户设置价格的程序。该程序应该会向您显示您的购物清单，最后根据您给出的价格进行编号。

products = []
product_price = []


add_product = input("Would you like to add an item?: ")

while add_product == "yes":
    item = input("Enter the product: ")
    products.append(item)
    item_price = input("How much does this item cost? ")
    product_price.append(item_price)
    print(f"{item} has been added to the cart. ")
    add_product = input("Would you like to add an item? ")

print("The contents of the shopping cart are: ")
zipobj = zip(products, product_price)
for i, prices in enumerate(zipobj, start = 1):
    print(i, prices)

我希望它打印出如下内容：

鞋子 - 50 美元
连衣裙 - 25 美元

我得到的是：

1 ('shoes', '50') 2 ('dress', '25')

我做错了什么？

谢谢

Answer 1

使用字符串格式来生成您想要的输出：

for i, (item, price) in enumate(zipobj, start=1):
    print(f"{i}. {item} - ${price}")

打印时不断加括号和引号

When printed keeps on putting parentheses and quotations

python

tuples

list

enumerate
