PyQt5 – How to clear the content of label | clear and setText method

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()

Argument : It takes no argument.

Code :

# importing the required libraries

from PyQt5.QtWidgets import *
from PyQt5 import QtCore
from PyQt5.QtGui import *
import sys

class Window(QMainWindow):
    def __init__(self):
        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())

Output :

Using setText() method –

Syntax : label.setText(“”)

Argument : It takes string as argument, here string will be blank.

Code :

# importing the required libraries

from PyQt5.QtWidgets import *
from PyQt5 import QtCore
from PyQt5.QtGui import *
import sys

class Window(QMainWindow):
    def __init__(self):
        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;")

        # replacing content with blank
        self.label_2.setText("")


        # 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())

Output :
