"Fill" refers to the dimension/space that is filled when you expand the 
widget (assuming "expand" is set to true). "fill=x" means the widget 
will expand horizontally (along the x axis). "fill=y" means that the 
widget will expand vertically (along the y axis). "fill=both" means the 
widget will expand in both direction.

Frederick Lundh has a good introduction to the packer here: 
http://effbot.org/tkinterbook/pack.htm

I find "pack" to be more flexible than "grid," so I prefer it for 
complex layouts. "grid" is better for simple layouts.

HTH,
