Qtimer and extra argument

[luca72]

Hello i hope that yo can reply to this question also if the argument is pyqt

i have a simple test:
def start_timer(self):
        self.timer = QTimer()
        testo = 'pressed'
        self.timer.singleShot(1000, self.metto_testo)
    
def test(self, testo):
        self.lineEdit.setText(testo)


How i can pass the variable testo to the def test?
If i use :
self.timer.singleShot(1000, self.metto_testo(testo)
i get error

Thanks
