根据在TKinter中单击的单选按钮，是否显示选项中的标签？

import tkinter as tk

window = tk.Tk()

selected_option = tk.IntVar()
selected_option.set(0)

option1 = tk.Radiobutton(window, text="选项1", variable=selected_option, value=1)
option2 = tk.Radiobutton(window, text="选项2", variable=selected_option, value=2)

label = tk.Label(window, text="这是一个标签")

def update_label():
    if selected_option.get() == 1:
        label.pack()
    else:
        label.pack_forget()

option1.pack()
option2.pack()
label.pack()

option1.config(command=update_label)
option2.config(command=update_label)

window.mainloop()
