Oops, forgot! The Scale widget outputs a single argument - the value of
the slider. You therefore could write:
command = lambda value : Calc(value)
or even simpler:
command = Calc
In the latter case, you're supplying your "calc" function as the function
to be called. Calc takes a single argument - the value of the slider, so
it fulfills the task. Note that we're passing "Calc" (the function
itself), not "Calc(...)" (the result of calling the function)
