You can remove QLayouts by getting their corresponding QLayoutItem and removing it. You should also be storing references to your Layouts, otherwise there is no other way to access them later on unless you know the widget they belong to.

datainputHbox = QHBoxLayout()
self.vlayout = QVBoxLayout(self)
layout.addLayout(datainputHbox)
pagedatainputdeletboxbutton1.clicked.connect(lambda: self.boxdelete(datainputHbox))

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