You could limit the value for the -o option with parser.add_option("-o", dest="ext", choices="exe txt pdf ppt".split()) and do the actual work outside the OptionParser. options, args = parser.parse_args() def process_exe(): # whatever actions = {"exe": process_exe, ...} actions[options.ext]() Peter -- http://mail.python.org/mailman/listinfo/python-list
