If so how?
You can easily have #1 with optparse.OptionParser(usage="…")¹, but optparse is deprecated in favor of argparse.ArgumentParser. I do not think you can have #2 with either optparse or argparse: OptionParser() would print the error message last, and ArgumentParser() would not print the description on error. Subclassing ArgumentParser might be feasible, though. ______ ¹ <http://PointedEars.de/devel/tools/text/odfinfo/> -- PointedEars Bitte keine Kopien per E-Mail. / Please do not Cc: me. -- http://mail.python.org/mailman/listinfo/python-list
