帮我用Python语言生成一段贪吃蛇游戏代码

好的，以下是一份基于Python的贪吃蛇游戏代码，希望能够帮助到您：

import pygame
import random

# 初始化游戏
pygame.init()

# 定义游戏窗口的大小和标题
window_width = 800
window_height = 600
game_display = pygame.display.set_mode((window_width, window_height))
pygame.display.set_caption('贪吃蛇游戏')

# 定义颜色
white = (255, 255, 255)
black = (0, 0, 0)
red = (255, 0, 0)
green = (0, 255, 0)

# 定义蛇的大小和速度
snake_block_size = 10
snake_speed = 15

# 定义字体
font_style = pygame.font.SysFont(None, 30)

# 显示分数
def show_score(score):
    score_text = font_style.render("分数：" + str(score), True, black)
    game_display.blit(score_text, [0, 0])

# 绘制蛇
def draw_snake(snake_block_size, snake_list):
    for x in snake_list:

    pygame.quit()
    quit()

game_loop()
