如何创建薪资/税计算器？

def calculate_tax(income):
    if income <= 5000:
        tax = 0
    elif income <= 8000:
        tax = (income - 5000) * 0.1
    else:
        tax = (income - 8000) * 0.2 + 3000 * 0.1
    return tax

def calculate_salary(base_salary, bonus=0, deductions=0):
    total_income = base_salary + bonus - deductions
    tax = calculate_tax(total_income)
    net_salary = total_income - tax
    return net_salary, tax

# 示例使用
base_salary = 6000
bonus = 1000
deductions = 500
net_salary, tax = calculate_salary(base_salary, bonus, deductions)
print(f"基本工资: {base_salary}")
print(f"奖金: {bonus}")
print(f"扣除项: {deductions}")
print(f"应纳税额: {tax}")
print(f"实际到手薪资: {net_salary}")
