Python GUI 学籍管理系统：学生信息增删改查及文本保存

这是一个使用 Python 的 tkinter 库构建的简单学籍管理系统，它提供学生信息的添加、删除、修改、查询功能，并将学生信息保存在文本文件中。

这个代码使用了 tkinter 库来创建 GUI 界面，并使用 Student 和 StudentManagementSystem 类来管理学生信息。你可以通过 GUI 界面输入学生的各项信息，并通过按钮来添加、删除、查找和显示所有学生信息。

为了将学生信息保存到文本文件中，你可以在 StudentManagementSystem 类中的 add_student 方法中添加代码。例如，你可以使用 open() 函数打开一个文本文件，并使用 write() 函数将学生信息写入文件。

希望这个示例代码能帮到你！
