简单的模拟用户登录 - 限定三次输入用户名密码机会

 1 count = 1
 2 system_username = 'admin'
 3 system_password = '123'
 4 system_code = 'qwer'
 5 while count <= 3:
 6     username = input('请输入用户名：')
 7     password = input('请输入密码：')
 8     code = input('请输入验证码')
 9     if code == system_code:
10         if username == system_username and password == system_password:
11             print('欢迎回来：' + username)
12         else:
13             print('用户名或密码输入错误！！！')
14     else:
15         print('您的验证码输入错误!')
16     count += 1
17 print('输入错误次数太多，请明日再来')
