python 中的變量不起作用，有人可以告訴我我的代碼有什么問題嗎？

Question

有人可以幫助我修復我的代碼，我是 python 的新手並且正在學習基礎知識但是我不明白為什么我不能讓“稅”部分打印一個值？ 即使按照教程一步一步進行。

完整腳本：

################### Item Descriptions ###################

lovely_loveseat_description = "Lovely Loveseat. Tufted polyester blend on wood. 32 inches high x 40 inches wide x 30 inches deep. Red or white."
lovely_loveseat_price = 254.00

stylish_settee_description = "Stylish Settee. Faux leather on birch. 29.50 inches high x 54.75 inches wide x 28 inches deep. Black."
stylish_settee_description = 180.50

luxurious_lamp_description = "Luxurious Lamp. Glass and iron. 36 inches tall. Brown with cream shade."
luxurious_lamp_price = 52.15

################### Total Formulas ###################

sales_tax = int(.884)

customer_one_itemization = "Lovely Loveseat. Tufted polyester blend on wood. 32 inches high x 40 inches wide x 30 inches deep. Red or white."
customer_one_total = " "
customer_one_total += str(lovely_loveseat_price)
customer_one_tax = customer_one_total * sales_tax

################### Prints ###################

print("Customer One Items")
print(customer_one_itemization)
print("Customer One Total")
print(customer_one_total)
print("Customer tax Total")
print(customer_one_tax)

我在 output 中得到以下內容：

Customer One Items
Lovely Loveseat. Tufted polyester blend on wood. 32 inches high x 40 inches wide x 30 inches deep. Red or white.
Customer One Total
 254.0
Customer tax Total
(THIS SHOULD PRINT THE TAX TOTAL)

Answer 1

這應該有效：

################### Item Descriptions ###################

lovely_loveseat_description = "Lovely Loveseat. Tufted polyester blend on wood. 32 inches high x 40 inches wide x 30 inches deep. Red or white."
lovely_loveseat_price = 254.00

stylish_settee_description = "Stylish Settee. Faux leather on birch. 29.50 inches high x 54.75 inches wide x 28 inches deep. Black."
stylish_settee_description = 180.50

luxurious_lamp_description = "Luxurious Lamp. Glass and iron. 36 inches tall. Brown with cream shade."
luxurious_lamp_price = 52.15

################### Total Formulas ###################

sales_tax = .088

customer_one_itemization = "Lovely Loveseat. Tufted polyester blend on wood. 32 inches high x 40 inches wide x 30 inches deep. Red or white."
customer_one_total = lovely_loveseat_price
customer_one_tax = customer_one_total * sales_tax

################### Prints ###################

print("Customer One Items")
print(customer_one_itemization)
print("Customer One Total")
print(customer_one_total)
print("Customer tax Total")
print(customer_one_tax)

Output：

Customer One Items
Lovely Loveseat. Tufted polyester blend on wood. 32 inches high x 40 inches wide x 30 inches deep. Red or white.
Customer One Total
254.0
Customer tax Total
22.352

您的代碼有幾個我必須修復的錯誤：

• 您通過將customer_one_total設置為""來初始化它
• lovely_loveseat_price作為str添加到customer_one_total
• sales_tax不應設置為int(.884) ，它僅為零。 根據您的評論，您希望它是.088
