项目名称：Tkinter小程序开发 2.项目描述： 利用Tkinter做一个简单的GUI应用小程序，实现一个特 定的功能、比如做一个计算器、学生信息管理系统等。 3.项目要求： 1.使用Tkinter创建用户界面，包括标签、文本框、按钮、菜单等控件。 2.使用面向对象编程的思想设计代码结构， 3.代码量：>100行

好的，以下是一个学生信息管理系统的示例代码，它包括学生信息的录入、查询、修改和删除等功能：

import tkinter as tk

class Student:
    def __init__(self, name, age, gender, score):
        self.name = name
        self.age = age
        self.gender = gender
        self.score = score

class StudentManagementSystem:
    def __init__(self, master):
        self.master = master
        master.title("Student Management System")

        # 创建标签和文本框
        tk.Label(master, text="Name: ").grid(row=0, column=0, padx=5, pady=5)
        self.name_entry = tk.Entry(master, width=30)
        self.name_entry.grid(row=0, column=1, padx=5, pady=5)

        tk.Label(master, text="Age: ").grid(row=1, column=0, padx=5, pady=5)
        self.age_entry = tk.Entry(master, width=30)
        self.age_entry.grid(row=1, column=1, padx=5, pady=5)

        tk.Label(master, text="Gender: ").grid(row=2, column=0, padx=5, pady=5)
        self.gender_entry = tk.Entry(master, width=30)
        self.gender_entry.grid(row=2, column=1, padx=5, pady=5)

        tk.Label(master, text="Score: ").grid(row=3, column=0, padx=5, pady=5)
        self.score_entry = tk.Entry(master, width=30)
        self.score_entry.grid(row=3, column=1, padx=5, pady=5)

        # 创建按钮
        tk.Button(master, text="Add", width=10, command=self.add_student).grid(row=4, column=0, padx=5, pady=5)
        tk.Button(master, text="Search", width=10, command=self.search_student).grid(row=4, column=1, padx=5, pady=5)
        tk.Button(master, text="Update", width=10, command=self.update_student).grid(row=4, column=2, padx=5, pady=5)
        tk.Button(master, text="Delete", width=10, command=self.delete_student).grid(row=4, column=3, padx=5, pady=5)

        # 创建菜单
        menubar = tk.Menu(master)
        master.config(menu=menubar)

        file_menu = tk.Menu(menubar)
        menubar.add_cascade(label="File", menu=file_menu)
        file_menu.add_command(label="Exit", command=master.quit)

        # 创建学生列表框
        tk.Label(master, text="Student List:").grid(row=5, column=0, padx=5, pady=5)

        self.student_listbox = tk.Listbox(master, width=50)
        self.student_listbox.grid(row=6, column=0, columnspan=4, padx=5, pady=5)

        # 初始化学生列表
        self.students = []
        self.refresh_student_list()

    def add_student(self):
        name = self.name_entry.get()
        age = int(self.age_entry.get())
        gender = self.gender_entry.get()
        score = float(self.score_entry.get())

        student = Student(name, age, gender, score)
        self.students.append(student)

        self.refresh_student_list()

        self.name_entry.delete(0, tk.END)
        self.age_entry.delete(0, tk.END)
        self.gender_entry.delete(0, tk.END)
        self.score_entry.delete(0, tk.END)

    def search_student(self):
        name = self.name_entry.get()

        for i, student in enumerate(self.students):
            if student.name == name:
                self.student_listbox.selection_clear(0, tk.END)
                self.student_listbox.selection_set(i)
                self.student_listbox.activate(i)
                break

    def update_student(self):
        selected_indices = self.student_listbox.curselection()

        if len(selected_indices) == 0:
            return

        index = selected_indices[0]

        name = self.name_entry.get()
        age = int(self.age_entry.get())
        gender = self.gender_entry.get()
        score = float(self.score_entry.get())

        student = Student(name, age, gender, score)
        self.students[index] = student

        self.refresh_student_list()

    def delete_student(self):
        selected_indices = self.student_listbox.curselection()

        if len(selected_indices) == 0:
            return

        index = selected_indices[0]

        del self.students[index]

        self.refresh_student_list()

    def refresh_student_list(self):
        self.student_listbox.delete(0, tk.END)

        for student in self.students:
            self.student_listbox.insert(tk.END, f"{student.name} ({student.age}, {student.gender}, {student.score})")

root = tk.Tk()
system = StudentManagementSystem(root)
root.mainloop()

这个学生信息管理系统有一个界面，包括四个文本框和四个按钮，用于录入、查询、修改和删除学生信息。它还有一个学生列表框，用于显示学生信息。你可以根据这个示例代码，自己编写一个 GUI 应用小程序。
