""" You can bind variables to tk widgets, so that they are updated when the value of the widget changes. 
 They can also be used to set the value of a widget.
In this example, we set the radio buttons to an integer variable called rbValue. 
Changing rbValue causes different radio buttons to be selected, and selecting the different radio buttons 
changes the value of rbValue so we can tell which button's been clicked.
You can find out more information on the tk variables at http://effbot.org/tkinterbook/variable.htm """

#the weight property is used when the window is resized
#so a weight of 3 will widen 3 times faster than with weight=1
#when the window size increasez
