Python 检验身份证号真伪

昨天python考试有一道检验身份证号的题目，要求输入身份证号，检验其是否正确，如果正确，则输出生日和性别。代码如下：

a=input()

b=[7,9,10,5,8,4,2,1,6,3,7,9,10,5,8,4,2]

def gender():

if a[-1]=="X" or eval(a[-2])%2!=0:

print("男性")

else:

print("女性")

def data():

year=a[6:10]

month=a[10:12]

day=a[12:14]

print("{}年{}月{}日".format(year,month,day))

def jianyan():

d=0

for i in range(0,len(a)-1):

d+=b[i]*eval(a[i])

d=d%11

if d==2 and a[-1]=="X":

print("True")

data()

gender()

elif d+eval(a[-1])==12:

print("True")

data()

gender()

elif d!=2 and a[-1]=="X":

print("False")

else:

print("False")

jianyan()
