I don't like the (a, b)[True] thing, but I use the fact that True is 1
and False is 0 sometimes.
EG, if I have 3 mutually exclusive command line options, I'll do something like:
if option_a + option_b + option_c != 1:
sys.stderr.write('{}: -a, -b and -c are mutually
exclusive\n'.format(sys.argv[0]))
