Explanation
This program is a simple example of a graphical user interface (GUI) application created using the Tkinter library in Python. The program contains three textboxes on the form, where the user can enter the ages of three persons in years. The user can then click a button, which triggers a function that calculates the average age of the three persons and shows the result in a message box.

The program uses the Tkinter library to create the GUI elements, including the textboxes and the button. The textboxes are created using the Entry class, which allows the user to enter text. The button is created using the Button class, which allows the user to trigger an action when it is clicked.

The program also includes a try-except block to handle the case where the user enters invalid input. When the user clicks the button, the program gets the values from the textboxes and calculates the average age using a simple mathematical formula. Then it shows the average age in a messagebox using the showinfo method of messagebox class.

The title of the program is SEO optimized by keeping it brief yet descriptive, which makes it easy for the user to understand the functionality of the program.
