在同一个类中使用不同函数时如何在Python中获取Checkbox的值

from tkinter import *

window = Tk()
checkbox = Checkbutton(window, text="Checkbox")
checkbox.pack()

def get_checkbox_value():
    value = checkbox.get()
    print(value)

button = Button(window, text="获取Checkbox的值", command=get_checkbox_value)
button.pack()

window.mainloop()

from tkinter import *

def get_checkbox_value():
    value = checkbox.get()
    print(value)

window = Tk()
checkbox = Checkbutton(window, text="Checkbox")
checkbox.pack()

button = Button(window, text="获取Checkbox的值", command=get_checkbox_value)
button.pack()

window.mainloop()
