 5 # 税率表, 2018.10新个税
 6 tax_ratio = OrderedDict()
 7 tax_ratio[(0, 5000)] = 0
 8 tax_ratio[(5000, 3000)] = 0.03
 9 tax_ratio[(3000, 12000)] = 0.1
10 tax_ratio[(12000, 25000)] = 0.2
11 tax_ratio[(25000, 35000)] = 0.25
12 tax_ratio[(35000, 55000)] = 0.3
13 tax_ratio[(55000, 80000)] = 0.35
14 tax_ratio[(80000, float('inf'))] = 0.45

17 # 计算税
18 def tax(income, social_benefits=0):
19     income -= social_benefits
20     total_tax = 0
21     for k, v in tax_ratio.items():
22         if income > k[1]:
23             income -= k[1]
24             total_tax += k[1] * v
25         elif k[0] < income < k[1]:
26             total_tax += income * v
27             break
28     return total_tax
29

31 if __name__ == '__main__':
32     print(tax(12705))
33     print(tax(15000, 2295))
34     print(tax(income=15000, social_benefits=2295))
35     print(tax(social_benefits=2295, income=15000))
