python - 大约一半的 if 语句无法正常工作
问题描述
我将使用基本运算符制作一个 python 程序来向用户索取收入，以便计算 2017 年和 2018 年的累进税。输出应如下所示：
Income: 15000
2017 tax: (tax amount here) #will skip the math for samples
2018 tax: (tax amount here)
到目前为止，我的程序会生成 2017 / 2018 年的两个打印件，但将停止在 2018 年嵌套的 if 括号 82501 到 157500（嵌套在第 4 个 elif 中）......这是我现在的程序，因为它很长我会标出它停止工作的地方。

我已经标记了行不通的行。澄清一下，嵌套的 if 和之前的打印输出 2017 年和 2018 年的结果，但是当收入在标记范围内或更大时，只会打印 2017 年的税收。
我在收入 82502 及以上的结果是这样的：
Enter your income to calculate tax: 82502
----------------------------------------------
Income: 82502.0
2017 tax: 16364.00
Enter your income as and integer with no commas:
已解决：感谢所有评论和回答，他们为我解决了一些问题！这是我重新设计的，似乎可以工作，所以我很满意。我将添加更多计算，因此希望也能顺利进行 :)

解决方案
只需完成程序将要执行的语句
income = 82502.0
将进入
elif income >= 37951 and income <= 91900:
但是对于 2018 年的计算，它不会满足里面的条件
if income >= 38701 and income <= 82500:
所以它无法计算 2018 年。它不会到达你标记它的地步。
2017 年的计算应独立于 2018 年的计算。在很多情况下，您的计算不会打印 2018 年的税款。
但是您确实进行了良好的测试，以发现您的程序无法正常工作。边缘情况通常会出现问题。
