【输入月收入和五险一金计算个人所得税】
个税计算公式
使用超额进税率的计算方法如下:
缴税＝全月应纳税所得额＊税率-速扣除数
实发工资应发工资-五险一金缴税
全月应纳税所得额＝（应发工资-四金）-5000
扣除标准:个税按5000元/月的起征标准算
diff: 差异/等级收费标准
rate: 税率
deduction: 速算扣除数
tax: 应个人所得税
salary: 税前收入
insurance: 五险一金
'''.replace('\n',' ')

salary = float(input('本月收入：'))
insurance = float(input('五险一金：'))
diff = salary - insurance - 5000
if diff <= 0:
    rate = 0
    deduction = 0
elif diff < 3000:
    rate = 0.03
    deduction = 0
elif diff < 12000:
    rate = 0.1
    deduction = 210
elif diff < 25000:
    rate = 0.2
    deduction = 1410
elif diff < 35000:
    rate = 0.25
    deduction = 2660
elif diff < 55000:
    rate = 0.3
    deduction = 4410
elif diff < 80000:
    rate = 0.35
    deduction = 7160
else:
    rate = 0.45
    deduction = 15160

tax = abs(diff * rate - deduction)
print('个人所得税: ￥%.2f元' % tax)
print('实际到手收入：￥%.2f元' % (diff + 5000 - tax))

Locate the Day01-15-Day03 branch-structure lesson content and review the sections for exercise 2 and exercise 5. Update the two exercise examples according to the issue, then verify that the Python snippets are correctly formatted and produce the intended output.
