i find out my what is my problem...

parser.add_argument("-p", "--port", help="Destination port (the port of the target's machine service, \
e.g 80 for HTTP, 22 for SSH and so on).")

have to change to this (add type=int ):

parser.add_argument("-p", "--port", type=int, help="Destination port (the port of the target's machine service, \
e.g 80 for HTTP, 22 for SSH and so on).")
