如何将单选按钮与tkinter中的combobox绑定？

import tkinter as tk
from tkinter import ttk

root = tk.Tk()
selected_option = tk.StringVar()

radio_button1 = tk.Radiobutton(root, text="Option 1", variable=selected_option, value="option1")
radio_button2 = tk.Radiobutton(root, text="Option 2", variable=selected_option, value="option2")
combo_box = ttk.Combobox(root)

def update_options(*args):
    if selected_option.get() == "option1":
        combo_box['values'] = ("Option A", "Option B", "Option C")
    elif selected_option.get() == "option2":
        combo_box['values'] = ("Option X", "Option Y", "Option Z")

# 绑定单选按钮的选择变化事件
selected_option.trace("w", update_options)

radio_button1.pack()
radio_button2.pack()
combo_box.pack()

root.mainloop()
