入力後にテキストを再入力するTkinter（Python）

Question

私はPython用にTkinterを使用しています。ユーザーがテキストウィジェットに何かを入力した後にテキストを再入力できるかどうかを調べようとしています。

現時点では、このような私のコードの出力：

私がしたい何がテキストフィールド内の中心に表示されるように入力したテキストのためです。私のコードは以下の通りです。すべてのテキストエントリは本質的に同じなので、ほとんどのコードは似ています。私は包括性のためだけにそれを含めていましたが、Text（...）オブジェクトの変更に対処しなければならないと確信しています。

ありがとうございます。

あなたはおそらく最も簡単な解決策は、ウィジェット内のデータをタグに再任意のキーのリリースにバインドを追加することで、内蔵の justify属性を持つ Entryウィジェットを使用することはできませんと仮定
