15位身份证补全为18位身份证的python实现

主要是看到了别人的算法：http://blog.jobbole.com/111556/
我自己写了个python的代码实现,感谢大侠去研究这样的算法

1. def transIDCard15To18(IdCardNo):
   
2.     ll=[]
   
3.     if IdCardNo is not None and len(IdCardNo.strip())==15:
   
4.         IdCardStr=IdCardNo.strip()
   
5.         for i in IdCardStr:
   
6.             ll.append(i)
   
7.         ll.insert(6,'9')
   
8.         ll.insert(6,'1')
   
9.         ll.append(transCardLastNo(ll))
   
10.     return "".join(ll)
    
11. 
    
12. 
    
13. 
    
14. def transCardLastNo(IDCardList):
    
15.     co=[7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2]
    
16.     varCode=['1','0','X','9','8','7','6','5','4','3','2']
    
17.     result=0
    
18.     for i in range(len(IDCardList)):
    
19.         result+=int(IDCardList[i]) * co[i]
    
20.     
    
21.     residue=result%11
    
22.     return varCode[residue]
    
23. 
    
24. 
    
25. 
    
26. print(transIDCard15To18("370986890623212"))
    
27. print(transIDCard15To18("370725881105149"))

结果如下：
