How to check if CTRL and SHIFT are pressed simultaneously in PyQt?

I found a lot of examples how to get key modifiers like this one. But I don't get it working for checking if they are pressed and hold at the same time. This should be rather easy, as CTRL+SHIFT are standard key combinations. From the above linked example: ``` modifiers = QtGui.QApplication.keyboardModifiers() if modifiers == QtCore.Qt.ShiftModifier: print('Shift+Click') elif modifiers == QtCore.Qt.ControlModifier: print('Control+Click') else: print('Click') ``` We see that either CTRL or SHIFT are tested for. But I need a check which finds if both are pressed at the same time. I tested lots of variants like this one: ``` if modifiers == (QtCore.Qt.ControlModifier and QtCore.Qt.ShiftModifier): ``` I found something written in C but I don't seem to be able to translate it.
