用Python中的sqlite3库和tkinter库编写一个学生信息管理系统，包括姓名，性别，学号，手机号，专业，班级

好的，我能为您提供帮助，以下是实现学生信息管理系统的Python代码：

import sqlite3
import tkinter as tk

# 创建一个数据库连接
conn = sqlite3.connect('students.db')

# 创建学生信息表
conn.execute('''CREATE TABLE STUDENTS
       (ID INT PRIMARY KEY     NOT NULL,
       NAME           TEXT    NOT NULL,
       GENDER         TEXT    NOT NULL,
       STUDENT_ID     TEXT    NOT NULL,
       PHONE_NUMBER   TEXT    NOT NULL,
       MAJOR          TEXT    NOT NULL,
       CLASS          TEXT    NOT NULL);''')

# 插入一些样本数据
conn.execute("INSERT INTO STUDENTS (ID,NAME,GENDER,STUDENT_ID,PHONE_NUMBER,MAJOR,CLASS) \
      VALUES (1, '张三', '男', '10001', '13812345678', '计算机科学', '计科1班')")

# 定义一个函数：在GUI中显示学生信息
def show_students():
    cursor = conn.execute("SELECT ID, NAME, GENDER, STUDENT_ID, PHONE_NUMBER, MAJOR, CLASS from STUDENTS")
    for row in cursor:
        print("ID = ", row[0])
        print("NAME = ", row[1])
        print("GENDER = ", row[2])
        print("STUDENT_ID = ", row[3])
        print("PHONE_NUMBER = ", row[4])
        print("MAJOR = ", row[5])
        print("CLASS = ", row[6])

# 定义一个函数：在GUI中添加学生信息
def add_student():
    id_val = id_entry.get()
    name_val = name_entry.get()
    gender_val = gender_entry.get()
    student_id_val = student_id_entry.get()
    phone_number_val = phone_number_entry.get()
    major_val = major_entry.get()
    class_val = class_entry.get()
    conn.execute("INSERT INTO STUDENTS (ID, NAME, GENDER, STUDENT_ID, PHONE_NUMBER, MAJOR, CLASS) \
                  VALUES (?, ?, ?, ?, ?, ?, ?)", (id_val, name_val, gender_val, student_id_val, phone_number_val, major_val, class_val))
    conn.commit()
    print("学生信息已添加成功！")

# 创建GUI界面并添加控件
window = tk.Tk()

id_label = tk.Label(window, text="学号")
id_label.grid(row=0, column=0)
id_entry = tk.Entry(window)
id_entry.grid(row=0, column=1)

name_label = tk.Label(window, text="姓名")
name_label.grid(row=1, column=0)
name_entry = tk.Entry(window)
name_entry.grid(row=1, column=1)

gender_label = tk.Label(window, text="性别")
gender_label.grid(row=2, column=0)
gender_entry = tk.Entry(window)
gender_entry.grid(row=2, column=1)

student_id_label = tk.Label(window, text="学号")
student_id_label.grid(row=3, column=0)
student_id_entry = tk.Entry(window)
student_id_entry.grid(row=3, column=1)

phone_number_label = tk.Label(window, text="手机号")
phone_number_label.grid(row=4, column=0)
phone_number_entry = tk.Entry(window)
phone_number_entry.grid(row=4, column=1)

major_label = tk.Label(window, text="专业")
major_label.grid(row=5, column=0)
major_entry = tk.Entry(window)
major_entry.grid(row=5, column=1)

class_label = tk.Label(window, text="班级")
class_label.grid(row=6, column=0)
class_entry = tk.Entry(window)
class_entry.grid(row=6, column=1)

show_students_button = tk.Button(window, text="显示学生信息", command=show_students)
show_students_button.grid(row=7, column=0)

add_student_button = tk.Button(window, text="添加学生信息", command=add_student)
add_student_button.grid(row=7, column=1)

window.mainloop()

以上代码实现了一个基本的学生信息管理系统，你可以将其运行在你的本地计算机上，将SQLite数据库存储的数据显示在GUI界面上，并且可以通过相应的输入框添加学生信息。更多关于Python Tkinter 和 SQLite库的使用可以查看官方文档。
