python - getopt

try:
options,args = getopt.getopt(sys.argv[1:],"hp:i:",["help","ip=","port="])
except getopt.GetoptError:
sys.exit()

for name,value in options:
if name in ("-h","--help"):
usage()
if name in ("-i","--ip"):
print 'ip is----',value
if name in ("-p","--port")

print 'port is----',value

options,args = getopt.getopt(sys.argv[1:],"hp:i:",["help","ip=","port="])

“hp:i:”
短格式 --- h 后面没有冒号：表示后面不带参数，p：和 i：后面有冒号表示后面需要参数

["help","ip=","port="]
