如何在用户输入的情况下重新启动pygame，并记录分数？

import pygame
from pygame.locals import *

pygame.init()
screen_width, screen_height = 800, 600
screen = pygame.display.set_mode((screen_width, screen_height))
pygame.display.set_caption("游戏标题")

def game_loop():
    game_over = False
    score = 0
    
    while not game_over:
        for event in pygame.event.get():
            if event.type == QUIT:
                pygame.quit()
                sys.exit()
            elif event.type == KEYDOWN:
                if event.key == K_SPACE:
                    # 用户按下空格键，重新启动游戏
                    game_loop()
        
        # 游戏逻辑处理
        # ...
        
        # 绘制游戏界面
        # ...
        
        pygame.display.update()

score += 1  # 假设每次更新分数加1

def game_over_screen(score):
    # 绘制游戏结束界面
    # ...
    
    # 保存分数到文件或数据库
    with open("scores.txt", "a") as file:
        file.write(str(score) + "\n")

if game_over:
    game_over_screen(score)
