一个登录页面
一个简单的登录表格，它接受一个用户名和密码，并使用一个密码和用户名的文件来验证它是否正确。为了使这个程序工作，你应该在同一目录下设置一个名为Accounts.txt 的文件。

注册
表格 一个注册表格，使用包布局管理器将各种小部件放置在一个相当有趣的布局中，接受用户的输入。然后，这些数据可以被保存到MySQL数据库作为永久存储。对于这个程序，你需要安装一个MySQL数据库来使用数据存储功能。

语法高亮器+代码编辑器
用Python Tkinter制作的一个比较复杂的图形用户界面项目。我们在这里制作的语法高亮器是相当粗糙的，但它有许多你在今天的简单代码编辑器（如Notepad++）中可以找到的功能。它可以给某些关键词、字符串和重要的单词着色，同时也有一定程度的自动缩进功能。
