需求： 让用户输入用户名密码 认证成功后显示欢迎信息 输错三次后退出程序 可以支持多个用户登录 用户3次认证失败后，退出程序，再次启动程序尝试登录时，还是锁定状态
# -*- coding:utf-8 -*- # author: Skyell flag = True account_list = {‘xiaopang‘:‘123‘,‘haohao‘:‘234‘} #账号密码 username = input(‘Please input your username:‘) lock_name = open(‘lockname_list.txt‘,‘r‘) for i in lock_name: lockname = i.strip() if lockname == username: print(‘your account has been locked!‘) break else: continue lock_name.close() if username != lock_name: password_wrong = 0 while flag: password = input(‘Please input your password:‘) acc_name = [keys for keys in account_list] #利用列表生成式将账号信息存入列表中 if username in acc_name: if account_list[username] == password: #判断账号、密码是否正确 print(‘welcome back!‘) flag = False break else: print(‘Please try again!‘) password_wrong +=1 if password_wrong==3: #密码错误3次，锁定用户 print(‘your account has been locked‘) lock_name = open(‘lockname_list.txt‘, ‘a+‘) lock_name.write(‘\n‘) lock_name.write(username) #将被锁定的账号写入锁定文件中 lock_name.close() else: print(‘Account is not found‘) flag = False break
基本实现需求，继续继续！
