Must function defs appear earlier than calls?

I'm using Tkinter, creating buttons and scales.  One of the buttons
should have a command option to execute a function that initializes some
class objects.  These objects take a scale object as one of their
initialization parameters, So I have to create the class objects after I
create the scales.

It seems that I must create the button that calls the initialization
function after that, or else the function assigned to the command option
is undefined.

But I want to create the button first, so that it appears near the top
of my frame.

I hope that's clear.  Now you see why I didn't describe that in my
original post!

And thanks for your help!
