f=open(\'user\',\'r\',encoding=\'utf-8\')

fstr=f.readlines()#读文件，读出来是列表

fuser=fstr[0:-1:2]#从开始没隔一个取一个值，这个是account

fpword=fstr[1::2]#这个是password，中间不写0.才能取到最后一个值

i = 1

while i <= 3:

for n in fuser:

fuser_account=n.strip()#取account付给变量，方便进行字符串对比

if account == fuser_account:

for m in fpword:

if password==fuser_pword:

print("welcome to my school")

exit()

f = open(\'incorrect-user\', \'r\', encoding=\'utf-8\')#读取incorrect-user账户里账号，准备做对比

for line in f:

if account==fuser_lock:#判断account是否已被锁定

print("your account has been locked")
