ゲーム「2048」をPythonで自作し、自作のAIに解かせます。
これ自体はありふれたテーマで、ググれば色々出てくるのですが、僕みたいな初心者向けに書かれた詳しい記事は見つからなかったので、敢えて書いてみることにしました。
この記事では、Pythonで「2048」を自作します。
なおこの記事は続編です。前の記事は以下のリンクからどうぞ。

前記事のおさらい
前回の記事（https://qiita.com/masa_ramen/items/b497e547a1298a905a2e ）では、Seleniumというライブラリを使ってWebページ上の「2048」をパソコンにプレイさせました。
Webページ上の「2048」のリンクは以下です[1]。
https://gabrielecirulli.github.io/2048/
for文で
「上」「右」「下」「左」「上」「右」「下」「左」「上」「右」「下」「左」「上」「右」「下」「左」「上」「右」「下」「左」「上」「右」「下」「左」「上」「右」「下」「左」「上」「右」「下」「左」「上」「右」「下」「左」「上」「右」「下」「左」・・・「上」「右」「下」「左」
のような指示を送信することで、パソコンがそこそこの得点をゲットする様子を見ました。
ところが知性皆無のポンコツな戦略では限界があるため、
盤面を認識して、
ある方向を送信した時の結果（=「1手先」の盤面）を計算して、
それがどれくらい「良い」かを評価し、一番「良い手」を選び続ける
プログラム
の作成が必要であるとの結論に至りました。
「2048」の自作が必要
盤面の認識については、前回も使ったSeleniumライブラリで対応できます。
しかし、認識した盤面において「1手先」を計算するためには「自分の頭の中」に「2048」が必要です。
パソコンが自分で「2048」のルールを理解し、そのルールに則って次の局面を計算する必要があるのです。
では、「2048」のルールを確認しましょう。
「2048」のルール
①はじめに4×4の空席がある
②このうちランダムな2ヶ所にタイルが出現する
③方向キーの入力を受け付ける（今回のプログラムでは、上を「u」、右を「r」、下を「d」、左を「l」としました）
④数字がくっついたら、くっついた後の数字を得点に加算する
⑤ランダムな場所に新しいタイルが出現する
（以下、③〜⑤を繰り返す）
新しく出現するタイルは、90%で「2」が出現し、10%で「4」が出現するとします。
#コード
あとはルールをPython語に翻訳するだけです。
愚直に書いたため、長くて読みにくいですごめんなさい🙏
皆さんも実際に遊んで見てください。
上に動かしたいときは「u」、右に動かしたいときは「r」、下に動かしたいときは「d」、左に動かしたいときは「l」と入力してください。
次回の記事では、いよいよ評価関数を導入して、それぞれの「次の1手」がどれくらい「良い」かを点数で表示する機能を実装します！お楽しみに！
