w = Label ( master, option=value, ... )

Various options of Label widget:
- anchor: This option controls where the text is positioned. The default anchor is CENTER.Other possible values are NW(North West is top left), N, NE(North East is top right), W, E, SW(South West is bottom left), S, SE(South East is bottom right)
- bg : The normal background color displayed behind the label and indicator.
- bd : The size of the border around the indicator. Default is 2 pixels.
- cursor : If you set this option to a cursor name (arrow, dot etc.), the mouse cursor will change to that pattern when it is over the label.

- image : To display a static image in the label widget, set this option to an image object.
- text : To display one or more lines of text in a label widget, set this option to a string containing the text. Internal newlines (“n”) will force a line break.

- underline : You can display an underline (_) below the nth letter of the text, counting from 0, by setting this option to n. The default is underline=-1, which means no underlining.
