[Tutor] how to retrieve values from scale widget(sample code is attached)????

how to retrieve values from scale widget(sample code is attached)????

I can figure out frames and the basic widget formats themselves, but I can't 
figure out how to retrieve data from this widget so I can use it as input 
data in some other part of a program.

Can you help???

(BTW, I think I am getting my clock program figured out (I think), that I 
was asking about earlier)

    f = string.atoi(s)
    f = f - 32
    c = f/9.
    c = c * 5.

    flabel["text"] = "Degrees Fahrenheit:  %s" % (s)
