Answer 1

As a generic answer: taken from here with slight, but important changes: you should not call widget.deleteLater(). At least in my case this caused python to crash

Global Function

def deleteItemsOfLayout(layout):
     if layout is not None:
         while layout.count():
             item = layout.takeAt(0)
             widget = item.widget()
             if widget is not None:
                 widget.setParent(None)
             else:
                 deleteItemsOfLayout(item.layout())

together with the boxdelete function from Brendan Abel's answer

def boxdelete(self, box):
    for i in range(self.vlayout.count()):
        layout_item = self.vlayout.itemAt(i)
        if layout_item.layout() == box:
            deleteItemsOfLayout(layout_item.layout())
            self.vlayout.removeItem(layout_item)
            break
