The Tk Toplevel widget can take a screen option when you create it's 
instance.

Example:

# left hand screen
top1 = Toplevel(root, screen=":0")

# right hand screen
top2 = Toplevel(root, screen=":1")

(this is untested as I only have one screen...)

If both screens are really only one screen (not sure how to describe 
that)  then setting the geometry on the toplevel instance would work 
too.


Example:

top1 = Toplevel(root)

# top left corner of 'whole' screen
top1.geometry("+1+1")

# top right corner of 'whole' screen
top1.geometry("-1+1")

# bottom left corner of 'whole' screen
top1.geometry("+1-1")

# bottom right corner of 'whole' screen
top1.geometry("-1-1")

These can be added to the normal geometry size options like so:

# top right and full screen?? (if running 1024x768!)
top1.geometry("1024x768+1+1")


If you need to find out how big your screen is:

top1.winfo_vrootwidth()
top1.winfo_vrootheight()
