Question

meal = float(input("Enter the price of the meal:\n"))
if meal>4.00:
    tax = meal * 1.13
    round(tax, 2)
    total = tax + meal
    print("Subtotal: $" + meal + "\n" + "Total Taxes: $" + tax + "\n" + "Total: $" + total)

我正在尝试为学校做作业，当我输出带有附加符号的代码时，它会产生此错误，但如果我使用逗号，它会打印出空格。我该如何解决这个问题？

Answer 1

将您的值转换为 str

print("Subtotal: $" + str(meal) + "\n" + "Total Taxes: $" + str(tax) + "\n" + "Total: $" + str(total))

或使用 f 字符串：

print(f"Subtotal: ${meal}\nTotal Taxes: ${tax}\nTotal: ${total}")

Answer 2

meal、tax 和 total 是浮点数，因此您需要使用 str()。

meal = float(input("Enter the price of the meal:\n"))
if meal>4.00:
    tax = meal * 1.13
    round(tax, 2)
    total = tax + meal
    print("Subtotal: $" + str(meal) + "\n" + "Total Taxes: $" + str(tax) + "\n" + "Total: $" + str(total))

我不断收到“TypeError: can only concatenate str (not“float”) to str”错误
