来个会python求解

有如下字典,请给所有考生增加一个加分 项,退伍军人加10分,其他考生加0分
a= |'001 ':{'name ':'张三',' age ':26,' ider ntity':'军人'
score':88},' 002 ': {'name ':'李四','age ':24,' ident tity ':'工人', score':78,' 003 ': {' name ':'王五',age ':22,' ident tity':'农民'，score':95},' 004 ': {'name ':'小明',' age ':25 ,' ident tity':'军人'，score':90

OK 马上写来：

a= {'001':{'name':'张三','age':26,'identtity':'军人','score':88},
    '002': {'name':'李四','age':24,'identtity':'工人', 'score':78},
    '003': {'name':'王五','age':22,'identtity':'农民','score':95},
    '004': {'name ':'小明',' age ':25 ,'identtity':'军人','score':90}
 }

for k,v in a.items():
    if v['identtity'] == '军人':
        a[k]['score'] = a[k]['score']+10

print(a)

运行结果：
