import sys
class Window(QMainWindow):
def __init__(self):
super().__init__()
# set the title
self.setWindowTitle("Python")
# setting geometry
self.setGeometry(100, 100, 600, 400)
# creating a label widget
self.label_1 = QLabel("old label ", self)
# setting up the border
self.label_1.setStyleSheet("border :3px solid black;")
# setting the alignment of the label
self.label_1.setAlignment(Qt.AlignRight)
# getting he alignment of the label
align = self.label_1.alignment()
# printing the align of label
print(align)
# resizing the label
self.label_1.resize(150, 40)
# moving the label
self.label_1.move(100, 100)
# creating a new label widget
self.label_2 = QLabel("new Label ", self)
# setting up the border
self.label_2.setStyleSheet("border :3px solid black;")
# moving the label
self.label_2.move(200, 200)
# resizing the label
self.label_2.resize(150, 40)
# setting the alignment using label_1 alignment
self.label_2.setAlignment(align)
# 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())
