python使用tkinter模块写名片管理系统，实现增删查改

好的，下面是一个简单的名片管理系统的实现示例：

import tkinter as tk

class Card:
    def __init__(self, name, phone):
        self.name = name
        self.phone = phone

class CardManager:
    def __init__(self):
        self.cards = []

    def add_card(self, card):
        self.cards.append(card)

    def remove_card(self, card):
        self.cards.remove(card)

    def search_card(self, name):
        for card in self.cards:
            if card.name == name:
                return card
        return None

    def update_card(self, card, name, phone):
        card.name = name
        card.phone = phone

class CardGUI:
    def __init__(self):
        self.manager = CardManager()
        self.window = tk.Tk()
        self.window.title("名片管理系统")
        self.create_widgets()

    def create_widgets(self):
        # 新增名片
        self.add_frame = tk.Frame(self.window)
        self.add_frame.pack(side=tk.TOP, padx=10, pady=10)
        tk.Label(self.add_frame, text="姓名：").grid(row=0, column=0)
        self.add_name_entry = tk.Entry(self.add_frame)
        self.add_name_entry.grid(row=0, column=1)
        tk.Label(self.add_frame, text="电话：").grid(row=1, column=0)
        self.add_phone_entry = tk.Entry(self.add_frame)
        self.add_phone_entry.grid(row=1, column=1)
        tk.Button(self.add_frame, text="新增", command=self.add_card).grid(row=2, column=1)

        # 删除名片
        self.remove_frame = tk.Frame(self.window)
        self.remove_frame.pack(side=tk.TOP, padx=10, pady=10)
        tk.Label(self.remove_frame, text="姓名：").grid(row=0, column=0)
        self.remove_name_entry = tk.Entry(self.remove_frame)
        self.remove_name_entry.grid(row=0, column=1)
        tk.Button(self.remove_frame, text="删除", command=self.remove_card).grid(row=1, column=1)

        # 查询名片
        self.search_frame = tk.Frame(self.window)
        self.search_frame.pack(side=tk.TOP, padx=10, pady=10)
        tk.Label(self.search_frame, text="姓名：").grid(row=0, column=0)
        self.search_name_entry = tk.Entry(self.search_frame)
        self.search_name_entry.grid(row=0, column=1)
        self.search_result_label = tk.Label(self.search_frame, text="")
        self.search_result_label.grid(row=1, column=1)
        tk.Button(self.search_frame, text="查询", command=self.search_card).grid(row=2, column=1)

        # 修改名片
        self.update_frame = tk.Frame(self.window)
        self.update_frame.pack(side=tk.TOP, padx=10, pady=10)
        tk.Label(self.update_frame, text="原姓名：").grid(row=0, column=0)
        self.update_old_name_entry = tk.Entry(self.update_frame)
        self.update_old_name_entry.grid(row=0, column=1)
        tk.Label(self.update_frame, text="新姓名：").grid(row=1, column=0)
        self.update_new_name_entry = tk.Entry(self.update_frame)
        self.update_new_name_entry.grid(row=1, column=1)
        tk.Label(self.update_frame, text="新电话：").grid(row=2, column=0)
        self.update_new_phone_entry = tk.Entry(self.update_frame)
        self.update_new_phone_entry.grid(row=2, column=1)
        tk.Button(self.update_frame, text="修改", command=self.update_card).grid(row=3, column=1)

    def add_card(self):
        name = self.add_name_entry.get()
        phone = self.add_phone_entry.get()
        card = Card(name, phone)
        self.manager.add_card(card)
        self.add_name_entry.delete(0, tk.END)
        self.add_phone_entry.delete(0, tk.END)

    def remove_card(self):
        name = self.remove_name_entry.get()
        card = self.manager.search_card(name)
        if card:
            self.manager.remove_card(card)
            self.remove_name_entry.delete(0, tk.END)
        else:
            self.remove_name_entry.delete(0, tk.END)
            self.remove_name_entry.insert(0, "不存在该名片")

    def search_card(self):
        name = self.search_name_entry.get()
        card = self.manager.search_card(name)
        if card:
            self.search_result_label.config(text="姓名：{}，电话：{}".format(card.name, card.phone))
            self.search_name_entry.delete(0, tk.END)
        else:
            self.search_result_label.config(text="不存在该名片")
            self.search_name_entry.delete(0, tk.END)

    def update_card(self):
        old_name = self.update_old_name_entry.get()
        new_name = self.update_new_name_entry.get()
        new_phone = self.update_new_phone_entry.get()
        card = self.manager.search_card(old_name)
        if card:
            self.manager.update_card(card, new_name, new_phone)
            self.update_old_name_entry.delete(0, tk.END)
            self.update_new_name_entry.delete(0, tk.END)
            self.update_new_phone_entry.delete(0, tk.END)
        else:
            self.update_old_name_entry.delete(0, tk.END)
            self.update_old_name_entry.insert(0, "不存在该名片")

    def run(self):
        self.window.mainloop()

if __name__ == "__main__":
    gui = CardGUI()
    gui.run()

这个程序使用了 `tkinter` 模块创建了一个 GUI 界面，在界面上提供了新增、删除、查询和修改名片的功能。其中，`Card` 类表示一个名片，`CardManager` 类负责管理所有名片，`CardGUI` 类负责创建 GUI 界面并与 `CardManager` 类交互来实现各种名片操作。
