python用tkinker编写好友管理系统，gui界面，多来几个代码

好的，下面是一个使用 tkinter 编写的简单好友管理系统的代码示例：

import tkinter as tk

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

class FriendManagementSystem:
    def __init__(self):
        self.friends = []
        self.selected_friend = None

        # 创建主窗口
        self.root = tk.Tk()
        self.root.title("好友管理系统")

        # 创建组件
        self.name_label = tk.Label(self.root, text="姓名：")
        self.name_entry = tk.Entry(self.root)
        self.age_label = tk.Label(self.root, text="年龄：")
        self.age_entry = tk.Entry(self.root)
        self.gender_label = tk.Label(self.root, text="性别：")
        self.gender_entry = tk.Entry(self.root)
        self.add_button = tk.Button(self.root, text="添加好友", command=self.add_friend)
        self.update_button = tk.Button(self.root, text="修改好友", command=self.update_friend, state=tk.DISABLED)
        self.delete_button = tk.Button(self.root, text="删除好友", command=self.delete_friend, state=tk.DISABLED)
        self.friend_listbox = tk.Listbox(self.root, selectmode=tk.SINGLE)
        self.friend_listbox.bind("<<ListboxSelect>>", self.select_friend)

        # 布局组件
        self.name_label.grid(row=0, column=0)
        self.name_entry.grid(row=0, column=1)
        self.age_label.grid(row=1, column=0)
        self.age_entry.grid(row=1, column=1)
        self.gender_label.grid(row=2, column=0)
        self.gender_entry.grid(row=2, column=1)
        self.add_button.grid(row=3, column=0)
        self.update_button.grid(row=3, column=1)
        self.delete_button.grid(row=3, column=2)
        self.friend_listbox.grid(row=4, columnspan=3)

        # 显示窗口
        self.show_friends()
        self.root.mainloop()

    def show_friends(self):
        self.friend_listbox.delete(0, tk.END)
        for friend in self.friends:
            self.friend_listbox.insert(tk.END, friend.name)

    def add_friend(self):
        name = self.name_entry.get()
        age = self.age_entry.get()
        gender = self.gender_entry.get()

        friend = Friend(name, age, gender)
        self.friends.append(friend)

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

        self.show_friends()

    def update_friend(self):
        name = self.name_entry.get()
        age = self.age_entry.get()
        gender = self.gender_entry.get()

        self.selected_friend.name = name
        self.selected_friend.age = age
        self.selected_friend.gender = gender

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

        self.show_friends()

    def delete_friend(self):
        self.friends.remove(self.selected_friend)
        self.selected_friend = None

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

        self.show_friends()

    def select_friend(self, event):
        index = self.friend_listbox.curselection()[0]
        self.selected_friend = self.friends[index]

        self.name_entry.delete(0, tk.END)
        self.name_entry.insert(0, self.selected_friend.name)

        self.age_entry.delete(0, tk.END)
        self.age_entry.insert(0, self.selected_friend.age)

        self.gender_entry.delete(0, tk.END)
        self.gender_entry.insert(0, self.selected_friend.gender)

        self.update_button.config(state=tk.NORMAL)
        self.delete_button.config(state=tk.NORMAL)

if __name__ == "__main__":
    app = FriendManagementSystem()

这个程序使用了 tkinter 的各种组件来实现一个简单的好友管理系统，包括添加、修改、删除好友等功能。你可以根据自己的需求修改代码，并添加自己的功能。
