Is there a way to perform “if” in python's lambda

The syntax you're looking for:

lambda x: True if x % 2 == 0 else False

But you can't use print or raise in a lambda.

Qlist selection mode

enum QAbstractItemView::SelectionMode

This enum indicates how the view responds to user selections:

Constant	Value	Description
QAbstractItemView::SingleSelection	1	When the user selects an item, any already-selected item becomes unselected, and the user cannot unselect the selected item by clicking on it.
QAbstractItemView::ContiguousSelection	4	When the user selects an item in the usual way, the selection is cleared and the new item selected. However, if the user presses the Shift key while clicking on an item, all items between the current item and the clicked item are selected or unselected, depending on the state of the clicked item.
QAbstractItemView::ExtendedSelection	3	When the user selects an item in the usual way, the selection is cleared and the new item selected. However, if the user presses the Ctrl key when clicking on an item, the clicked item gets toggled and all other items are left untouched. If the user presses the Shift key while clicking on an item, all items between the current item and the clicked item are selected or unselected, depending on the state of the clicked item. Multiple items can be selected by dragging the mouse over them.
QAbstractItemView::MultiSelection	2	When the user selects an item in the usual way, the selection status of that item is toggled and the other items are left alone. Multiple items can be toggled by dragging the mouse over them.
QAbstractItemView::NoSelection	0	Items cannot be selected.

The most commonly used modes are SingleSelection and ExtendedSelection.

Remove selected item from the list

def removeSel(self):
    listItems=self.listA.selectedItems()
    if not listItems: return        
    for item in listItems:
       self.listA.takeItem(self.listA.row(item))
