In this article, we will see how we can easily clear/erase the content of the label of PyQt5 application. This can be done in two ways –

  1. Using clear() method, this will clear the content of the label.
  2. Using setText() method with passing a blank string, this will update the content with blank string.

Using clear() method –

Syntax : label.clear()

        super().__init__()
          
        # set the title
        self.setWindowTitle("Label")
  
        # setting  the geometry of window
        self.setGeometry(0, 0, 400, 300)
  
        # creating a label widget
        self.label_1 = QLabel("Label", self)
  
        # moving position
        self.label_1.move(100, 100)
  
        # setting up border
        self.label_1.setStyleSheet("border: 1px solid black;")
  
        # creating a label widget
        self.label_2 = QLabel("Hidden Label", self)
  
        # moving position
        self.label_2.move(100, 150)
  
        # setting up border
        self.label_2.setStyleSheet("border: 1px solid black;")
  
        # clearing the data
        self.label_2.clear()
  
  
        # show all the widgets
        self.show()
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
