计算个人所得税python

以下是计算个人所得税的Python代码：

def calculate_tax(income):
    # 定义税率表
    TaxTable = [(0, 500, 0.05), (500, 2000, 0.10), (2000, 5000, 0.15), (5000, 20000, 0.20), (20000, 40000, 0.25), (40000, 60000, 0.30), (60000, 80000, 0.35), (80000, 100000, 0.40), (100000, 1e10, 0.45)]
    # 计算应纳税所得额
    taxable_income = income - 3500
    # 如果应纳税所得额小于等于0，则不需要缴纳个人所得税
    if taxable_income <= 0:
        return 0
    # 遍历税率表，计算应缴纳的税款
    tax = 0
    for i in range(len(TaxTable)):
        if taxable_income > TaxTable[i][0]:
            if taxable_income > TaxTable[i][1]:
                tax += (TaxTable[i][1] - TaxTable[i][0]) * TaxTable[i][2]
            else:
                tax += (taxable_income - TaxTable[i][0]) * TaxTable[i][2]
            if i == len(TaxTable) - 1:
                break
    # 返回应缴纳的个人所得税
    return tax

使用方法：

income = 10000 # 个人收入
tax = calculate_tax(income) # 计算个人所得税
print("个人所得税：%.2f" % tax) # 输出个人所得税
