如何同时打开Pygame窗口和Tkinter窗口？

import pygame
import tkinter as tk
from threading import Thread

def pygame_window():
    pygame.init()
    pygame.display.set_mode((400, 300))
    pygame.display.set_caption("Pygame Window")
    
    running = True
    while running:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                running = False
                pygame.quit()

def tkinter_window():
    root = tk.Tk()
    root.title("Tkinter Window")
    root.geometry("400x300")
    
    label = tk.Label(root, text="Hello, Tkinter!")
    label.pack()
    
    root.mainloop()

if __name__ == "__main__":
    pygame_thread = Thread(target=pygame_window)
    tkinter_thread = Thread(target=tkinter_window)
    
    pygame_thread.start()
    tkinter_thread.start()
