[BRLTTY] Understanding brltty on a linux machine

Well if you are doing a simple 'print' statement in Python, it generates 
a new line by default, so the cursor is on the line after the output.  
You have to move the Braille window up to read it.  If you do something like

ans=input('enter text: ')

Now the cursor should be on the line where it says 'enter text'. Maybe 
type 'clear' before you run your script.  If it doesn't work like I 
describe, you might be hitting a terminal display bug. Without knowing 
exactly what you are doing, I'm just guessing.
