The IDLE program does not work with the screen readers I use on the Mac or Windows. A screen reader is a program that grabs the text on the screen and converts it into speech output, at least this is the 50000 feet explanation.  I cannot see the screen at all.

Python also has a console debugger. -d does not invoke it; -d is for something else.

   $ python -m pdb myscript.py
