私はtkinterを使って定義されたRhombusクラスを使ってRhombusを描画しようとしています。下の私のコードでは、Rectangleクラスを使ってRhombusを取得しました.Tkinterを使って異なるサイズのRhombusを描画するにはどうすればいいのでしょうか？ - すなわちTkinterを使ってRombusを描くにはどうすればいいですか？

それを描くことができます。ポストコードの詳細については、[最小限の完全かつ検証可能な例の作成方法]（http://stackoverflow.com/help/mcve）を参照してください。 –
ポリゴンを描画するにはポイントが必要です。[create_polygon]（http：// infohost .nmt.edu/tcc/help/pubs/tkinter/web/create_polygon.html）。あなたの菱形は何のポイントも持っていないので、それを描くことはできません。 – furas
