MessageBox Widget in Tkinter

In tkinter, the messagebox module provides a set of dialog boxes that can be used to display messages, warnings, and errors, as well as ask questions or confirm actions. The messagebox isn't exactly a widget like Label or Button, but it behaves in a similar way by displaying a pop-up window.
