Основываясь на этом ответе (вторая часть первого ответа - «Обновление: As @ArtOfWarfare ...») - Tkinter: виджет Treeview , я попытался заполнить Treeview всеми дисками, но только последним.это работает правильно.Есть идеи?Я знаю, что есть способ заполнить диск с самого начала, но я думаю, что для всех дисков это слишком.
