How to close one of the windows in Tkinter

[Larz60+]

to remove, use windowname.destroy() - it's gone

or windowname.withdraw() - removed from screen, but not destroyed

windowname.iconify() - lowered and iconified (click to restore)

there is also lift and lower, which places a window on top of or behind another window, and if they are the same size, and at same location, can be used to cycle several windows.
