帮我写一个有图形化界面的通讯录系统

好的，这个项目需要使用 GUI 框架和数据库来实现。我建议使用 Python 的 tkinter 模块作为 GUI 框架，以及 SQLite 作为数据库。

以下是实现步骤：

1. 首先安装 tkinter 和 SQLite3

pip install tkinter
pip install sqlite3

2. 创建一个 GUI 窗口，包含添加联系人、查找联系人、显示联系人等按钮。

import tkinter as tk

root = tk.Tk()
root.title("通讯录系统")

# 添加按钮
add_button = tk.Button(root, text="添加联系人")
add_button.pack()

# 查找按钮
search_button = tk.Button(root, text="查找联系人")
search_button.pack()

# 显示按钮
show_button = tk.Button(root, text="显示联系人")
show_button.pack()

root.mainloop()

3. 创建一个数据库来存储联系人信息。在程序启动时，如果数据库不存在，则创建一个新的数据库。

import sqlite3

conn = sqlite3.connect('contacts.db')
c = conn.cursor()

# 创建表格
c.execute('''CREATE TABLE IF NOT EXISTS contacts
             (id INTEGER PRIMARY KEY AUTOINCREMENT,
             name TEXT,
             phone TEXT,
             email TEXT)''')

conn.commit()
conn.close()

4. 实现添加联系人功能。点击添加联系人按钮后，弹出一个窗口，要求输入联系人的姓名、电话和电子邮件，并将这些信息保存到数据库中。

def add_contact():
    # 创建新窗口
    add_window = tk.Toplevel(root)

    # 姓名标签和输入框
    name_label = tk.Label(add_window, text="姓名")
    name_label.pack()
    name_entry = tk.Entry(add_window)
    name_entry.pack()

    # 电话标签和输入框
    phone_label = tk.Label(add_window, text="电话")
    phone_label.pack()
    phone_entry = tk.Entry(add_window)
    phone_entry.pack()

    # 邮箱标签和输入框
    email_label = tk.Label(add_window, text="邮箱")
    email_label.pack()
    email_entry = tk.Entry(add_window)
    email_entry.pack()

    # 添加按钮
    def add():
        name = name_entry.get()
        phone = phone_entry.get()
        email = email_entry.get()
        conn = sqlite3.connect('contacts.db')
        c = conn.cursor()
        c.execute("INSERT INTO contacts (name, phone, email) VALUES (?, ?, ?)", (name, phone, email))
        conn.commit()
        conn.close()
        add_window.destroy()

    add_button = tk.Button(add_window, text="添加", command=add)
    add_button.pack()

5. 实现查找联系人功能。点击查找联系人按钮后，弹出一个窗口，要求输入关键字（可以是姓名、电话或电子邮件），并显示匹配的联系人信息。

def search_contact():
    # 创建新窗口
    search_window = tk.Toplevel(root)

    # 关键字标签和输入框
    keyword_label = tk.Label(search_window, text="关键字")
    keyword_label.pack()
    keyword_entry = tk.Entry(search_window)
    keyword_entry.pack()

    # 查找按钮
    def search():
        keyword = keyword_entry.get()
        conn = sqlite3.connect('contacts.db')
        c = conn.cursor()
        c.execute("SELECT * FROM contacts WHERE name LIKE ? OR phone LIKE ? OR email LIKE ?", ('%' + keyword + '%', '%' + keyword + '%', '%' + keyword + '%'))
        result = c.fetchall()
        conn.close()

        # 显示结果
        for row in result:
            tk.Label(search_window, text=row[1]).pack()
            tk.Label(search_window, text=row[2]).pack()
            tk.Label(search_window, text=row[3]).pack()
            tk.Label(search_window, text="").pack()

    search_button = tk.Button(search_window, text="查找", command=search)
    search_button.pack()

6. 实现显示联系人功能。点击显示联系人按钮后，弹出一个窗口，显示所有联系人的信息。

def show_contacts():
    # 创建新窗口
    show_window = tk.Toplevel(root)

    conn = sqlite3.connect('contacts.db')
    c = conn.cursor()
    c.execute("SELECT * FROM contacts")
    result = c.fetchall()
    conn.close()

    # 显示结果
    for row in result:
        tk.Label(show_window, text=row[1]).pack()
        tk.Label(show_window, text=row[2]).pack()
        tk.Label(show_window, text=row[3]).pack()
        tk.Label(show_window, text="").pack()

show_button = tk.Button(root, text="显示联系人", command=show_contacts)
show_button.pack()

完整代码如下：

import tkinter as tk
import sqlite3

# 创建数据库
conn = sqlite3.connect('contacts.db')
c = conn.cursor()
c.execute('''CREATE TABLE IF NOT EXISTS contacts
             (id INTEGER PRIMARY KEY AUTOINCREMENT,
             name TEXT,
             phone TEXT,
             email TEXT)''')
conn.commit()
conn.close()

# 添加联系人
def add_contact():
    # 创建新窗口
    add_window = tk.Toplevel(root)

    # 姓名标签和输入框
    name_label = tk.Label(add_window, text="姓名")
    name_label.pack()
    name_entry = tk.Entry(add_window)
    name_entry.pack()

    # 电话标签和输入框
    phone_label = tk.Label(add_window, text="电话")
    phone_label.pack()
    phone_entry = tk.Entry(add_window)
    phone_entry.pack()

    # 邮箱标签和输入框
    email_label = tk.Label(add_window, text="邮箱")
    email_label.pack()
    email_entry = tk.Entry(add_window)
    email_entry.pack()

    # 添加按钮
    def add():
        name = name_entry.get()
        phone = phone_entry.get()
        email = email_entry.get()
        conn = sqlite3.connect('contacts.db')
        c = conn.cursor()
        c.execute("INSERT INTO contacts (name, phone, email) VALUES (?, ?, ?)", (name, phone, email))
        conn.commit()
        conn.close()
        add_window.destroy()

    add_button = tk.Button(add_window, text="添加", command=add)
    add_button.pack()

# 查找联系人
def search_contact():
    # 创建新窗口
    search_window = tk.Toplevel(root)

    # 关键字标签和输入框
    keyword_label = tk.Label(search_window, text="关键字")
    keyword_label.pack()
    keyword_entry = tk.Entry(search_window)
    keyword_entry.pack()

    # 查找按钮
    def search():
        keyword = keyword_entry.get()
        conn = sqlite3.connect('contacts.db')
        c = conn.cursor()
        c.execute("SELECT * FROM contacts WHERE name LIKE ? OR phone LIKE ? OR email LIKE ?", ('%' + keyword + '%', '%' + keyword + '%', '%' + keyword + '%'))
        result = c.fetchall()
        conn.close()

        # 显示结果
        for row in result:
            tk.Label(search_window, text=row[1]).pack()
            tk.Label(search_window, text=row[2]).pack()
            tk.Label(search_window, text=row[3]).pack()
            tk.Label(search_window, text="").pack()

    search_button = tk.Button(search_window, text="查找", command=search)
    search_button.pack()

# 显示联系人
def show_contacts():
    # 创建新窗口
    show_window = tk.Toplevel(root)

    conn = sqlite3.connect('contacts.db')
    c = conn.cursor()
    c.execute("SELECT * FROM contacts")
    result = c.fetchall()
    conn.close()

    # 显示结果
    for row in result:
        tk.Label(show_window, text=row[1]).pack()
        tk.Label(show_window, text=row[2]).pack()
        tk.Label(show_window, text=row[3]).pack()
        tk.Label(show_window, text="").pack()

# 创建 GUI 窗口
root = tk.Tk()
root.title("通讯录系统")

# 添加按钮
add_button = tk.Button(root, text="添加联系人", command=add_contact)
add_button.pack()

# 查找按钮
search_button = tk.Button(root, text="查找联系人", command=search_contact)
search_button.pack()

# 显示按钮
show_button = tk.Button(root, text="显示联系人", command=show_contacts)
show_button.pack()

root.mainloop()
