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.

On 11 April 1979, forces of the Uganda National Liberation Army, backed by Tanzania, captured Kampala, the capital of Uganda. This ended the Uganda–Tanzania War and led to the removal of Idi Amin from power. He was overthrown by Ugandan rebel forces and Tanzanian troops because his government was widely opposed for violence, repression, and political killings. Amin fled into exile and later lived in Saudi Arabia where he died in 2003 at Jeddah from organ failure.

#Sudan slams #Uganda for hosting paramilitary chief

#Hemeti on Friday met with Ugandan President Yoweri #Museveni at #Entebbe's State House, a day after a United Nations probe found his forces had committed acts of genocide in #Darfur.
Sudan's foreign ministry on Sunday criticised the meeting, saying the #RSF's atrocities had been "documented by the international community and condemned by regional organisations of which Uganda is a member", including the African Union & the Intergovernmental Authority on Development (#IGAD).
Daglo, speaking during his visit, said he travelled to Uganda after President Museveni was approached by the Sudanese army seeking his mediation.
His visit came a week ...
