调试 Python 计算税码

Question

下面的代码应该计算不同人从字典中读取的所得税并将他们的税返回到字典中，这是我在回答某个测验时编写的； X 国使用如下所示的累进比例税率为其公民计算税收：

年收入：0 - 1000

税率：0%

年收入：1,001 - 10,000

税率：10%

年收入：10,001 - 20,200

税率：15%

年收入：20,201 - 30,750

税率：20%

年收入：30,751 - 50,000

税率：25%

年收入：超过50,000

税率：30%

    tax = {}
    def calculate_tax(income):
      for key, value in income.items():
        if value <= 1000:
          income_tax = 0
          tax = {key : income_tax}
        elif value in range(1001,10000):
          tax1 = 0 
          tax2 = 0.1 * (value - 1000)

          tax = {key : income_tax}
        elif value > 50000:
          tax1 = 0
          tax2 = 0.1 * 9000
          tax3 = 0.15 * 10200
          tax4 = 0.20 * 10550
          tax5 = 0.25 * 19250
          tax6 = 0.3 * (value - 50000)
          income_tax = tax1+tax2+tax3+tax4+tax5+tax6
          tax = {key : income_tax}
      return tax
    income = {‘Alex’: 500, ‘James’: 20500,‘Kinuthia’: 70000}

}

谁能帮我看看我的代码有什么问题？

以下是我收到的错误信息。您的代码中有一个 ERROR/BUG 结果：

Answer 1

您的代码中有一个非 ascii 字符。看着它我会说这是你使用的引号。将它们替换为常规引号：

注意：如果您想在字符串或其他内容中使用非 ascii 字符，您需要在顶部包含文件编码，但只有在需要时才这样做

 # -*- coding: utf-8 -*-

Answer 2

在代码的这一行：

#income = {‘Alex’: 500, ‘James’: 20500,‘Kinuthia’: 70000}

不要使用反引号，使用普通引号并记住这是 Python，而不是 MySQL 数据库.
