python代碼實(shí)現(xiàn)2048游戲？相信很多沒有經(jīng)驗(yàn)的人對(duì)此束手無策，為此本文總結(jié)了問題出現(xiàn)的原因和解決方法，通過這篇文章希望你能解決這個(gè)問題。
一、分析與函數(shù)設(shè)計(jì)
1.1 游戲玩法
2048這款游戲的玩法很簡單，每次可以選擇上下左右滑動(dòng)，每滑動(dòng)一次，所有的數(shù)字方塊都會(huì)往滑動(dòng)的方向靠攏，系統(tǒng)也會(huì)在空白的地方亂數(shù)出現(xiàn)一個(gè)數(shù)字方塊，相同數(shù)字的方塊在靠攏、相撞時(shí)會(huì)相加。（介紹來自百度百科）
1.2 函數(shù)設(shè)計(jì)
_init _() 初始化4*4游戲地圖，分?jǐn)?shù)等游戲基本數(shù)據(jù)
is_gameover() 判斷是否結(jié)束游戲
rannumber() 玩家每次移動(dòng)時(shí)在地圖上隨機(jī)生成2、4
show() 在控制臺(tái)打印出4*4游戲地圖
print_score() 在控制臺(tái)打印出當(dāng)前分?jǐn)?shù)
up(), upmove() 上移
down(), downmove() 下移
left(), leftmove() 左移
right(), rightmove() 右移
nextstep() 讀取玩家按鍵
二、代碼實(shí)現(xiàn)

1.地圖的儲(chǔ)存與表示：目前沒有界面設(shè)計(jì)，因此就用二維數(shù)組直接儲(chǔ)存與表示
2.數(shù)組越界：調(diào)試代碼中遇到過五六次，除了牢記要邊緣檢測(cè)外， and 語句左右條件順序也要有講究。
例：while(temp<=2 and self.number[temp+1][j]==0 ) 注：self.number為4*4的二維數(shù)組
當(dāng)temp=3時(shí)，語句在temp<=2 被阻塞，不會(huì)執(zhí)行self.number[temp+1][j]==0，此時(shí)沒有問題;
若語句改為while(self.number[temp+1][j]==0 and temp<=2), 先執(zhí)行self.number[temp+1][j]==0，此時(shí)編譯器報(bào)錯(cuò)數(shù)組越界
