In some code I review I see a line

QtCore.pyqtSlot(str)

@QtCore.pyqtSlot(str)

before the definition of the function that is the slot function and connected to a signal. I have always worked without that line. So what is it good for? How is the syntax, @ or not, use of str...

Thanks for any help
