----------------
This module contains a Python script utilizing the PyQt5 library to create a
basic graphical user interface (GUI) application. The application showcases a
tabbed window with two tabs, each containing a grid of numbers. The first tab
displays numbers from 1 to 100, and the second tab displays numbers from 101 to
200, arranged in a grid format.
