В фреймворке PyQt (и PySide тоже) часто встречается настройка чего-либо с помощью так называемых флагов.
widget.setWindowFlags(Qt.Window)
Взаимодействие нескольких флагов делается с помощью бинарных (или побитовых) операторов.
Несколько флагов можно указать с помощью оператора "|"
list_item.setFlags(Qt.ItemIsSelectable | Qt.ItemIsEnabled)
исключить флаг из уже имеющегося набора можно так
list_item.setFlags(list_item.flags() ^ Qt.ItemIsEnabled)
Добавить новый флаг к имеющимся можно так
list_item.setFlags(list_item.flags() | Qt.ItemIsEnabled)
А проверка наличия делается так
is_enabled = item.flags() & Qt.ItemIsEnabled > 0
Почему именно так? Всё дело в том как именно работают побитовые операторы. Но об этом в следующем посте.

Our Group Tax Specialist, Ang Sim Tay, represented the #IRASFam as a panellist on 'Pillar Two: Global Minimum Tax' at the recent IFA Asia Pacific Regional Conference in Kuala Lumpur.
At the conference, leading tax experts from across the region discussed technical challenges surrounding new developments in Base Erosion Profit Shifting 2.0, transfer pricing and cross-border dispute resolution.
“The conference offered valuable insights into how Malaysia and Indonesia are approaching Pillar Two implementation,” Ang Sim reflected. “The robust exchange of perspectives on emerging tax issues was also enlightening. I’m particularly grateful for IFA Malaysia’s warm hospitality, which made my experience even more memorable.”
