python的贪吃蛇代码

以下是一个简单的 Python 贪吃蛇游戏代码示例：

import pygame

import random
 
pygame.init()

# 游戏板块大小

# 定义颜色

blue = (50, 153, 213)
 
# 创建游戏板块
dis = pygame.display.set_mode((board_width, board_height))
pygame.display.set_caption('贪吃蛇')
 
# 定义贪吃蛇的大小和速度
snake_block = 10
snake_speed = 30

# 显示分数

    value = font_style.render("Score: " + str(score), True, white)
