私は6秒間画像を表示してラジオボタンを使って別のページにジャンプし、画像について自分の気持ちを評価できるようにしようとしています。次の画像を表示する。しかし、15秒をカウントダウンするには、time.sleep（）関数を使用しました。これは、ラジオボタンを押してもプログラムを非常に遅くします（しかし、クリックすると、ボタンはまだ押されます）。カウントダウンがプログラムに影響を与えないようにする方法があるのかどうかは疑問だが、時間切れになると次のページにジャンプする。ここに私のコードは次のとおりです。それは実行したイベントに応答できるからmainloop()を保つため、tkinterプログラムでtime.sleep()を使用してtime.sleep blocks tkinter.Buttonを押す

tkinterでtime.sleepを使用しないでください。プログラムが応答しなくなるだけです。 – abccd
マルチスレッドを使用する必要がありますか？どんな詳細も配慮されています。 –
