1、贪吃蛇源码，初始源码来自于网络。初学 python，做了部分修改，加了些有趣的功能进行测试。增加了部分注释；增加背景设置；增加历史高分统计；增加当前玩家排名；增加幸运食物，吃了有惊喜！开始：回车键暂停：空格键操作：控制上下左右（ w、s、a、d ） or（ up、down 、left 、right ）自动背景开启和关闭： L 手动背景 RGB 值微调：r、g、b 键（L开启才可用）游戏界面Python 源码名师资料总结 - - -精品资料欢迎下载 - - - - - - - - - - - - - - - - - - 名师精心整理 - - - - - - - 第 1 页，共 7 页 - - -
