使用Python Tkinter编写的简易发送邮件程序

最近学习了下Tkinter，就想写点小东西练习下，这样可以更深入一点，同时也提高兴趣，下面是自己使用tkinter写的一个使用SMTP的简易发送邮件程序，主要由一个登陆窗口和发送邮件窗口组成，用户在登陆窗口输入用户名和密码验证OK后即可登陆邮箱发送邮件。

若用户名或者密码为空则会提示用户

点击clear可以清除当前用户名和密码

若用户名和密码登陆成功后，会弹出发送邮件界面：

send to：填写你的目标发送地址

subject： 邮件主题

下面的文本输入框可以输入邮件内容

点击下面的send按钮即可发送邮件，点击new mail则会清除当前所有已填写的内容。

若邮件发送成功，则会弹出提示对跨框：

下面是代码，不足之处多多指教！
