运行以下Python代码:
import tkinter as tk
def change_text():
label.config(text="Changed text")
root = tk.Tk()
label = tk.Label(root, text="Original text")
label.pack()
button = tk.Button(root, text="Change text", command=change_text)
button.pack()
root.mainloop()
当点击“Change text”按钮后,标签的文本会变成?( )
保持不变
"Changed text"
"Button clicked!"
"Original text"
