Question

我有此代码来计算税金。我遇到NameError: name 'raw_input' is not defined这样的语法错误，不知道为什么？我是编码的新手，对此主题了解甚少。就像我花了很多时间写完几行，并且经过一些长期的研究之后才明白什么是我。

我写了一些东西，这给了我一个错误，我不确定自己的错误。就像我在痛苦的一段时间后做了类似的事情一样，float()做到了这一点。不确定我缺少什么？附注：我阅读了如何正确上传代码以供人们使用，例如最低版本。我认为我不太了解它要我做什么。很抱歉，如果它违反了规则或使其难以阅读！

# input of tax status
tax_status = raw_input('Enter your tax status(single or married) : ')
# validate tax status
while tax_status.strip().lower() != 'single' and tax_status.strip().lower() != 'married':
    print('Invalid value. Tax status can be eiher single or married')
    tax_status = raw_input('Enter your tax status(single or married) : ')
#input of income             
income = float(raw_input('Enter your income: '))
# validate income > 0
while income <= 0 :
    print('Invalid value. Income must be greater than 0')
    income = float(raw_input('Enter your income: '))
tax_amount = 0
# calculate tax amount based on tax_status and income
if tax_status == 'single':
    if income <= 9700:
        tax_amount = (10*income)/100
    elif income <= 39475:
        tax_amount = (12*income)/100
    elif income <= 84200:
        tax_amount = (22*income)/100
    elif income <=160725:
        tax_amount = (24*income)/100
    elif income <= 204100:
        tax_amount = (32*income)/100
    elif income <= 510300:
        tax_amount = (35*income)/100
    else:
        tax_amount = (37*income)/100
else:
    if income <= 19400:
        tax_amount = (10*income)/100
    elif income <= 78950:
        tax_amount = (12*income)/100
    elif income <= 168400:
        tax_amount = (22*income)/100
    elif income <=321450:
        tax_amount = (24*income)/100
    elif income <= 408200:
        tax_amount = (32*income)/100
    elif income <= 612350:
        tax_amount = (35*income)/100
    else:
        tax_amount = (37*income)/100
# output the tax amount               
print('Your tax amount is $%.2f' %(tax_amount))

我至少想知道我做错了什么，我该如何找出解决方案？就像我想念的那样，它导致了我这个问题，而当我尝试运行时却没有？

这是一种更清洁的编写方式，应该使用python中的某些标准约定来工作。您遇到的特定错误是因为raw_input是python2，并且已被input取代。

income = int(input('Enter your income: '))
tax_status = input('Enter your tax status(single or married) : ').lower()

if tax_status == 'single':
    SingleIncomeLevel = {10:9700, 12:39475, 22:84200, 24:160725, 32:204100, 35:510300}
    for multiplier in SingleIncomeLevel:
        if income <= SingleIncomeLevel[multiplier]:
            tax_amount = (multiplier*income)/100
        else:
            tax_amount = (37*income)/100
else:
    marriedIncomeLevel = {10:19400, 12:78950, 22:168400, 24:321450, 32:408200, 35:612350}
    for multiplier in marriedIncomeLevel:
        if income <= marriedIncomeLevel[multiplier]:
            tax_amount = (multiplier*income)/100
        else:
            tax_amount = (37*income)/100
print(f"Your tax amount is {tax_amount}")

不明白为什么会收到错误消息“ NameError：未定义名称'raw_input'”
