By this point in this book, creating a PyQt GUI to display a couple of numbers should be a walk in the park. Just to make things interesting and to create a stylish look, we're going to use a widget that we haven't talked about yet—QLCDNumber.

First, create a base widget in MainWindow.__init__(), as follows:
