測試代碼的Python語法錯誤

Question

這是我的代碼：

ItemName = input("Enter your item name: ")
PricePerPound = float(input("Enter the Price per pound: "))
ItemWeightPounds = float(input("Enter the weight of the item in pounds: "))
ItemWeightOunces = float(input("Enter the weight of the item in Ounces: "))
UnitPrice = (PricePerPound/16)
TotalPrice = (PricePerPound * ItemWeightPounds + ItemWeightOunces/16)
print("The Unit Price for your " + ItemName + " is: $" + UnitPrice)
print("The Total Price for your " + ItemName + " is: $" + TotalPrice)

Traceback (most recent call last):
print("The Unit Price for your " + ItemName + " is: $" + UnitPrice)
TypeError: Can't convert 'float' object to str implicitly

每當我在python中運行它時，我都會收到上述錯誤，有人可以確定我的代碼存在問題嗎？

Answer 1

您太早關閉了print語句。

您要打印的所有內容必須在方括號之間：

print("The Unit Price for your " + ItemName + " is: $" + str(UnitPrice))
print("The Total Price for your " + ItemName + " is: $" + str(TotalPrice))

您還需要投你的float -和int -objects到string ，因為你只能串聯（ + ） string -objects。
