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 the check-box
        checkbox = QCheckBox('Check Box', self)

        # setting geometry of check box
        checkbox.setGeometry(200, 150, 100, 30)

        # setting check box state to checked
        checkbox.setText("Caption")
