初めて質問します。足りない情報があれば指摘してください。
環境としてはJupyter Notebookでpythonのプログラムを作っています。
ex13.ipynbという家や雲、木、蝶々などが描画されるプログラム(以下に添付)に対して、ex21.ipynbというR.jpg画像がスクリーンの上部及び下部で横に繰り返して流し、スクリーン全体でブラウンで運動するプログラム(以下に添付)を参考にex13.ipynbのプログラムの雲が横に流れるかつ、蝶々がブラウン運動するように改変せよという課題が出ました。
自分なりに改変してみたのですが雲や蝶々がそもそも消消えたり上手くいきません。自分なりに改変したプログラム(ex13改.ipynb)も以下に添付しますのでおかしな点があれば指摘していただければ幸いです。正しいコードなども教えていただければ尚嬉しいです。よろしくお願いします。
