python的Tkinter包，如何返回所选的选项？

from tkinter import *
from tkinter.ttk import Combobox

window = Tk()
combo = Combobox(window)

options = ["Option 1", "Option 2", "Option 3"]
combo['values'] = options

def get_selected_option():
    selected_option = combo.get()
    print("Selected Option:", selected_option)

button = Button(window, text="Get Selected Option", command=get_selected_option)
button.pack()

window.mainloop()
