python计算个人所得税

以下是一个简单的 Python 代码片段，用于计算个人所得税：

income = float(input("请输入年收入："))
taxable_income = income - 5000  # 免征额为5000元
if taxable_income <= 0:
    tax = 0
elif 0 < taxable_income <= 3000:
    tax = taxable_income * 0.03
elif 3000 < taxable_income <= 12000:
    tax = taxable_income * 0.1 - 210
elif 12000 < taxable_income <= 25000:
    tax = taxable_income * 0.2 - 1410
elif 25000 < taxable_income <= 35000:
    tax = taxable_income * 0.25 - 2660
elif 35000 < taxable_income <= 55000:
    tax = taxable_income * 0.3 - 4410
elif 55000 < taxable_income <= 80000:
    tax = taxable_income * 0.35 - 7160
else:
    tax = taxable_income * 0.45 - 15160
print("个人所得税为：{:.2f}元".format(tax))

这个代码片段将用户输入的年收入减去免征额5000元，然后根据税率表计算个人所得税。注意，这个税率表是适用于中国的个人所得税税率表，如果你所在的国家有不同的税率表，请根据实际情况进行修改。
