python tkinter如何在特定的网格空间中更改小部件的标签？

import tkinter as tk

window = tk.Tk()

grid = tk.Grid()

label = tk.Label(window, text="初始标签")

label.grid(row=0, column=0)

def change_label_text():
    label.config(text="新标签")

button = tk.Button(window, text="更改标签", command=change_label_text)

button.grid(row=1, column=0)

window.mainloop()
