tkinterボタンが関数を呼び出さない

Question

私は、ユーザーがtkinterを使ってRock、Paper、Scissorsをプレイできるようにする初心者プログラマーです。私はクラスでtkinterを学んだことはありませんが、これは私の最終的なプロジェクトなので、私は感銘を受ける新しいことを学ぼうとしていました。

私はすべての配置方法を見つけ出すことができましたが、私のボタンは何もしないようです。終了ボタンは機能しますが、他にはありません。通訳のエラーは出ていません。どんな助けでも大歓迎です。あなたがする必要があるwinOrLossラベルのテキストを変更するため

Answer 1

表示は変わりません：winOrLoss.configure(text=win_or_loss)、ちょうどwin_or_lossを変更すると、ラベル内容は変更されません。あなたがwin_or_loss.set("new string")を行い、ラベルの内容を変更するには、

win_or_loss = StringVar() 
winOrLoss = Label(textvariable=win_or_loss) 

、その後：

もう一つの可能​​性はSTRINGVARを使用することです。
