After that iam going to create my main window class that extends from QWidget,  in our Window class we add some requirements of our Window like title, geometry and icon. also we have called our InitUI() method in here.





In this method we are going to create QVBoxLayout object, because we are going to add lcdnumber in this layout. also we have created the LCDNumber object.





Now we create a slot or method for connecting to the clicked signal of our QPushButton, it i just a Random Generator method.




Also every PyQt5 application must create an application object.





Finally, we enter the mainloop of the application. The event handling starts from this point.

So this will be the result for our QLCDNumber.
