            if (user,password) == (username,passwd):
                print('%s login success'% user)
                mathch_flag = True#设置登录认证标志位
                break #跳出for循环

    if mathch_flag == False and loggin_time < 2: #登录认证不匹配
        print('username or password error,please try again')
        loggin_time += 1
    else: #登录认证成功
        with open('account_lock', 'a+') as f:
            f.write('%s\n'% user )
            print('you have been locked ')
            break
代码不足之处：用户被锁定时，只是第三次输入的用户名被锁定到文件中，不符合逻辑
