very simple python port scanner

import socket
from socket import *
import sys


target = raw_input("Enter hostname: ")

addr = gethostbyname(target)
print("ip addres: ",addr)

for port in range(1,1000):
    s = socket(AF_INET,SOCK_STREAM)
    result = s.connect_ex((addr,port))
    if(result == 0):
        print("port %d: Open "%(port,))
