from optparse import OptionParser

parser = OptionParser(usage = "usage: %prog [options] arg" )
parser.add_option("-u", "--url", action=‘append‘, dest="urlname",  help=‘this is a url‘)
parser.add_option("-p", "--path", action=‘append‘, dest="pathname",  help=‘this is a path‘)
(options,args) = parser.parse_args()
print parser.parse_args()
print options, type(options)
print options.urlname, type(options.urlname)
print options.pathname

python test_optparse.py -h输出
