The event loop doesn ' t only handle events fromThe user (such as mouse clicks andKey presses)orThe windowing system (such as redraw events andwindow configuration messages), it also handle operations queued by Tkinter itself. Among these operations is geometry management (queued by the pack method) anddisplay updates. This also means that the application window would notappear before you enter the main loop."""
