同时运行两个python tkinter按钮

import tkinter as tk
import threading

def button1_click():
    print("Button 1 clicked")

def button2_click():
    print("Button 2 clicked")

def run_buttons():
    root = tk.Tk()

    button1 = tk.Button(root, text="Button 1", command=button1_click)
    button1.pack()

    button2 = tk.Button(root, text="Button 2", command=button2_click)
    button2.pack()

    root.mainloop()

if __name__ == "__main__":
    thread = threading.Thread(target=run_buttons)
    thread.start()
