IDLE, based on tkinter based on tcl/tk has a feature to vertically zoom 
an editor window to the full usable height, which is vertical pixel - 
top and or bottom taskbar pixels.  The only way we found to do that is 
to go full screen, get the window size, and revert to previous size. 
Not foolproof (or rather, not expert-proof), but a best-known effor.
