Alternatively, I prefer something nicer:
import optparse
p = optparse.OptionParser(usage="%prog [options]")
p.add_option("--list1", action="store_const", const=["blue", "red",
"green"], dest="worklist", help="use the first setting")
p.add_option("--list2", action="store_const", const=["red", "yellow",
"orange"], dest="worklist", help="use the second setting")
opt, args = p.parse_args()
if opt.worklist is None or len(args) != 0:
p.print_help()
raise SystemExit(2)
This looks longer, but gives you a nice commandline parse that does not
bomb out if you do not provide any argument, that is easy to expand, etc.
[caveat: the code above is typed into my mailer, so untested, and from
memory :) ]
