问如何实现Python tkinter中三个Listbox的同步滚动条？

import tkinter as tk
from tkinter import ttk

def on_scroll(event, *listboxes):
    print(event, event.delta)
    # 根据滚动事件获取滚动条的滚动位置
    x = event.x
    y = event.y
    if event.num == 5 or event.delta > 0:
        # 向上滚动或鼠标滚轮向上滚动
        y = -1
    elif event.num == 4 or event.delta < 0:
        # 向下滚动或鼠标滚轮向下滚动
        y = 1
    # # 更新所有Listbox的滚动位置
    for lbox in listboxes:
        lbox.yview_scroll(int(-1*(event.delta/120)), "units")

def create_listbox_with_scrollbar(master, listbox, scrollbar):
    # 将滚动条的command设置为更新Listbox的滚动位置
    scrollbar.config(command=lambda *args: listbox.yview(*args))
    # 将Listbox的滚动命令设置为滚动条的滚动函数
    listbox.config(yscrollcommand=lambda *args: scrollbar.set(*args))
    # 将Listbox和滚动条添加到主窗口
    listbox.pack(side=tk.LEFT, fill=tk.BOTH, expand=True)
    scrollbar.pack(side=tk.LEFT, fill=tk.Y)

def create_app():
    root = tk.Tk()
    root.title("同步滚动的Listbox")

    # 创建三个Listbox和它们的滚动条
    listbox1 = tk.Listbox(root, width=20, height=10)
    scrollbar1 = ttk.Scrollbar(root, orient="vertical", command=listbox1.yview)

    listbox2 = tk.Listbox(root, width=20, height=10)
    scrollbar2 = ttk.Scrollbar(root, orient="vertical", command=listbox2.yview)

    listbox3 = tk.Listbox(root, width=20, height=10)
    scrollbar3 = ttk.Scrollbar(root, orient="vertical", command=listbox3.yview)

    # 将Listbox和滚动条添加到主窗口
    create_listbox_with_scrollbar(root, listbox1, scrollbar1)
    create_listbox_with_scrollbar(root, listbox2, scrollbar2)
    create_listbox_with_scrollbar(root, listbox3, scrollbar3)

    # 绑定滚动事件到所有Listbox
    for lbox in [listbox1, listbox2, listbox3]:
        lbox.bind("<MouseWheel>", lambda event: on_scroll(event, listbox1, listbox2, listbox3))

    # 填充一些示例数据到Listbox
    for i in range(100):
        listbox1.insert(tk.END, f"Item 1 {i}")
        listbox2.insert(tk.END, f"Item 2 {i}")
        listbox3.insert(tk.END, f"Item 3 {i}")

    root.mainloop()

create_app()
