貪吃蛇python源碼

1、文檔供參考，可復(fù)制、編制，期待您的好評與關(guān)注！ 貪吃蛇源碼，初始源碼來自于網(wǎng)絡(luò)。初學(xué)python，做了部分修改，加了些有趣的功能進(jìn)行測試。增加了部分注釋；增加背景設(shè)置；增加歷史高分統(tǒng)計；增加當(dāng)前玩家排名；增加幸運食物，吃了有驚喜！開始：回車鍵暫停：空格鍵操作：控制上下左右（ w、s、a、d ） or（ up、down、left、right）自動背景開啟和關(guān)閉： L手動背景RGB值微調(diào)：r、g、b 鍵（L開啟才可用）游戲界面Python 源碼"""貪吃蛇"""import randomimport sysimport timeimpor
