class Window(QMainWindow):

    def __init__(self):
        super().__init__()

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 600, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

    # method for widgets
    def UiComponents(self):
        # creating a radio button
        self.radio_button = QRadioButton("Radio button", self)

        # setting geometry of radio button
        self.radio_button.setGeometry(200, 150, 120, 40)

        # setting help text
        self.radio_button.setWhatsThis(
            "To learn more about radio button go to GfG")

        # creating label to show help text
        label = QLabel(self)

        # setting geometry of label
        label.setGeometry(200, 200, 350, 30)

        # getting help of text of radio button
        text = self.radio_button.whatsThis()

        # showing text in label
        label.setText(text)

# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())
