SyntaxError：无效的语法，python3

Question

income=float(input("enter the annual income: ")

if income<85528:
  tax=(income-556.02)*0.18
else:
  tax=(income-85528)*0.32+14839.02

tax=round(tax,0)
print("the tax is: ", tax, "thalers")

为什么它总是在第 2 行给出错误？

Answer 1

您在第一行缺少括号：“）”。 它可以通过以下方式修复：

income = float(input("enter the annual income: "))

完整程序：

income = float(input("enter the annual income: "))

if income < 85528:
    tax = (income - 556.02) * 0.18
else:
    tax = (income - 85528) * 0.32 + 14839.02

tax = round(tax, 0)
print("the tax is: ", tax, "thalers")

回报：

enter the annual income: 435
the tax is:  -22.0 thalers
