用Python中的sqlite3库和tkinter库编写一个学生信息管理系统，包括学号，姓名，性别，专业，班级，手机号。可以添加和删除学生信息，并且显示学生信息

非常感谢您的问题，我会根据您的要求，为您提供答案。

以下是用Python中的sqlite3库和tkinter库编写一个学生信息管理系统的代码：

import sqlite3
import tkinter as tk
from tkinter import messagebox

# 连接数据库
con = sqlite3.connect('student.db')
cur = con.cursor()

# 创建学生信息表
cur.execute('CREATE TABLE IF NOT EXISTS students (id INTEGER PRIMARY KEY AUTOINCREMENT, name TEXT, gender TEXT, major TEXT, class TEXT, phone TEXT)')

# 添加学生信息
def add_student():
    name = name_entry.get()
    gender = gender_entry.get()
    major = major_entry.get()
    class_ = class_entry.get()
    phone = phone_entry.get()
    if name and gender and major and class_ and phone:
        cur.execute('INSERT INTO students (name, gender, major, class, phone) VALUES (?, ?, ?, ?, ?)', (name, gender, major, class_, phone))
        con.commit()
        messagebox.showinfo(title='Success', message='Add student successfully!')
    else:
        messagebox.showerror(title='Error', message='Please fill in all fields!')

# 删除学生信息
def delete_student():
    id_ = id_entry.get()
    if id_:
        cur.execute('DELETE FROM students WHERE id = ?', (id_,))
        con.commit()
        messagebox.showinfo(title='Success', message='Delete student successfully!')
    else:
        messagebox.showerror(title='Error', message='Please enter the ID of student to be deleted!')

# 显示学生信息
def show_student():
    result = ''
    cur.execute('SELECT * FROM students')
    rows = cur.fetchall()
    if rows:
        for row in rows:
            result += f'ID: {row[0]}\nName: {row[1]}\nGender: {row[2]}\nMajor: {row[3]}\nClass: {row[4]}\nPhone: {row[5]}\n\n'
        messagebox.showinfo(title='Student List', message=result)
    else:
        messagebox.showwarning(title='Empty', message='No student information to show!')

# 创建主窗口
root = tk.Tk()
root.title('Student Information Management')
root.geometry('300x300')

# 添加组件
id_label = tk.Label(root, text='ID:')
id_label.pack()
id_entry = tk.Entry(root)
id_entry.pack()

name_label = tk.Label(root, text='Name:')
name_label.pack()
name_entry = tk.Entry(root)
name_entry.pack()

gender_label = tk.Label(root, text='Gender:')
gender_label.pack()
gender_entry = tk.Entry(root)
gender_entry.pack()

major_label = tk.Label(root, text='Major:')
major_label.pack()
major_entry = tk.Entry(root)
major_entry.pack()

class_label = tk.Label(root, text='Class:')
class_label.pack()
class_entry = tk.Entry(root)
class_entry.pack()

phone_label = tk.Label(root, text='Phone:')
phone_label.pack()
phone_entry = tk.Entry(root)
phone_entry.pack()

add_button = tk.Button(root, text='Add', command=add_student)
add_button.pack()

delete_button = tk.Button(root, text='Delete', command=delete_student)
delete_button.pack()

show_button = tk.Button(root, text='Show', command=show_student)
show_button.pack()

# 运行主窗口
root.mainloop()

# 关闭数据库连接
con.close()

这是一个基本的学生信息管理系统，通过使用sqlite3库创建了students表，利用tkinter库创建了用户界面，实现了添加、删除、显示学生信息的功能。您可以根据自己的需要对代码进行修改和完善。希望对您有帮助！
