ありがとう！しかし、そのコードはうまくいきません。ウィンドウが開きますが、次のエラーが発生し、次のエラーが発生します。

は、整数の引数を必要とする関数があり、その関数の引数として代わりに浮動小数点プリミティブを受け取っていることを示している。  124行目と136行目はガターとボールの衝突チェックを担当しており、どちらも修正する必要があります。  根本的な原因は、20行目と21行目のHALF_PAD_WIDTHとHALF_PAD_HEIGHTの計算が、プログラムの先頭でpythonの整数除算演算子(//)ではなく、float除算演算子(/)を使って計算されていることにあるようです。  しかし、関数への引数を整数にキャストする方が簡単な場合もあります。  pythonの "range "関数は開始位置と停止位置に整数の引数を必要とするので、124行目と136行目のpython range関数への各入力引数は、TypeErrorを解決するために整数にキャストされました。

以下は修正されたpythonスクリプトです：
