Tkinter PanedWindow

Tkinter PanedWindow is known as a container widget that contains one or more child widgets and can arrange horizontally or vertically. Each pane contains one widget and each pair of panes is separated by a movable sash. By moving a sash causes the widgets on either side of the sash to be resized.
