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.

i get that people are more comfortable with defined rules and structure but i also think queer people lost when they started resorting to dictionary definitions for what labels mean
the queer umbrella is meant to deviate from the norm of rigid boxes and definitions and to decide that lesbian means Only this, bi means Only this, etc, is directly contradicting what queer means. each and every label is going to have a unique meaning to the person using it and that is how it’s supposed to be. if you’re not comfortable with that…sorry?
basically if someone tries to tell you you’re using a label wrong:
