How to clear or remove item from layout scroll area or widget or updatePySide2

Question

I need remove item in layout in scroll area, Because I want to update the items None of the following methods worked for me

for i in reversed(range(self.verticalLayout_2.count()):
    x = self.verticalLayout_2.itemAt(i).widget()
    x.deleteLater()

.

for i in reversed(range(self.verticalLayout_2.count()):
    x = self.verticalLayout_2.itemAt(i).widget().deleteLater()

This is out error:

AttributeError: 'NonyType' object has no attribute 'deleteLater'

Just for information, I am importing a ui file to run the PySide2 interface
