Why do I need to put two options for this script to print the path? if I just specify the option and argument... $ python <script>.py -p xxxx Usage: <script>.py [-p dir] [--part=dir]
<script>.py: error: No options specified So I need to give it two arguments... $ python <script>.py --part xxxx y xxxx Desired output: $ python <script>.py --part xxxx xxxx $ python <script>.py --part xxxx y Usage: <script>.py [-p dir] [--part=dir] <script>.py: error: some message ---- #/usr/bin/python import optparse def main(): parser = optparse.OptionParser(usage="%prog [-p dir] [--part=dir] ", version="%prog 1.0") parser.add_option( "-p", "--part", dest="directory", help="process target directory", metavar="dir") (options, args) = parser.parse_args() if len(args) != 1: parser.error("No options specified") path = options.directory print path if __name__ == "__main__": main() -- http://mail.python.org/mailman/listinfo/python-list
