1.源码

开发库使用：pygame random
直接在终端运行：pip install pygame
pycharm安装库：文件-设置-项目-Python 解释器

import pygame

pygame.init()# 设置窗口大小
screen_width = 800
screen_height = 600
screen = pygame.display.set_mode((screen_width, screen_height))# 设置标题
pygame.display.set_caption("Snake Game")# 设置蛇的初始位置
snake_x = 350
snake_y = 350# 设置蛇的速度
snake_speed = 20# 设置蛇的身体
snake_body = [(snake_x, snake_y)]# 设置食物的位置
food_x = random.randint(0, screen_width - 10)
