As we all know, python uses underlines and double underlines as significant characters. But fonts, including programmers' fonts, generally design underlines to run together. This makes it hard to identify single from double, or double from triple underlines (at least for me).
I have modified the droid Sans Mono font to provide underlines which may be distinguished from each other. (I also augmented the slashed zero to be more to my liking). Give it a try. If you like it, great. If not, no big deal. http://code.google.com/p/droid-sans-mono-py/ Den -- http://mail.python.org/mailman/listinfo/python-list
