Python 2.7 posting, and getting result from web site

I appreciate the help in advance. I am trying to write a python script that posts an IP address to a site referenced below, and get the results printed out in the terminal or file, and then read the file immediately after.

Here is my script:

#!/usr/bin/env python

import requests


IP = raw_input("Enter IP address here: ")

Alert_URL = 'http://ift.tt/GTMqlz'


def submit_form():
    """Submit a form"""
    payload = IP

    # make a get request
    resp = requests.get(Alert_URL)
    print "Response to GET request: %s" % resp.content

    # send POST request
    resp = requests.post(Alert_URL, payload)
    print "Headers from a POST request response: %s" % resp.headers
    # print "HTML Response: %s" %resp.read()


if __name__ == '__main__':
    submit_form()

The site has section to input IP addresses on the web page, and inspecting the site I found lines to input as follows:

<form method=POST onsubmit="document.forms[0].submit.disabled='true';">
IP or Domain <input onclick="this.value='';" name=q value=11.11.154.23>

I would like to post an IP address that I want to check to the site using the input section above somehow. For instance using raw_input to post into the 'value=' section, and get the result.

Thanks for the help.
