Python GUI 学籍管理系统：添加、删除、更新和查找学生信息
下面是一个使用 Python GUI 编写的学籍管理系统的例子：
import tkinter as tk
from tkinter import messagebox
class Student:
def __init__(self, name, gender, age, student_id, grade, python_score, c_score, db_score):
self.name = name
self.gender = gender

self.student_id = student_id
self.grade = grade
self.python_score = python_score
self.c_score = c_score
self.db_score = db_score

self.root = root
self.root.title('学籍管理系统')

该学籍管理系统使用了tkinter库来构建GUI界面。通过在文本框中输入学生信息，可以添加、删除、更新和查找学生信息，并且可以将学生信息导出到txt文档中。
