Запомните последнее место открытия

Question

Я хочу, чтобы getOpenFileName открывала тот же файл автоматически после открытия файла. Я пробовал решение из этого , как заставить getOpenFileName запомнить последний путь открытия? , но это не сработало.

Я опубликовал код GUI и основной код. GetOpenFileName находится в def singleBrowse

мой текущий код:
