今天刚刚学习的python

1，同一用户名的秘密输入错误3次后将被锁定
2.用户名和密码都正确时，显示登陆成功


#!/usr/bin/env python

username = ['yuzo','hy']  #存储用户名
password = ['123123','454545']      #存储对应的密码
locking = []        #用于锁定
n = 0       #计算输入了几次
while True:
    UserName = input('name：')
    if UserName not in locking:
        if UserName in username:
            PassWord = input('password：')
            if PassWord == password[username.index(UserName)]:
                print ('登录成功')
                exit()
            else:
                n = n+1
                if n == 3:
                    locking.append(UserName)
                print ('用户名或者密码错误，登录失败')
        else:
            PassWord = input('password：')
            print ("用户名或者密码错误，登录失败")
    else:
        print ("该用户已被锁定")
