Logging on Twitter with requests

I'm trying to make a Python script to log into Twitter with requests (through another site) based on a PHP script that I made that worked. But throw the next error

  

Traceback (most recent call last): File   "C: /Users/User/Desktop/instabot-twitbot/logueo_twitter.py", line   51, in       login = s.post (url_login, data = login_post, allow_redirects = True) File "C: \ Python27 \ lib \ site-packages \ requests \ sessions.py", line 555,   in post       return self.request ('POST', url, data = data, json = json, ** kwargs) File "C: \ Python27 \ lib \ site-packages \ requests \ sessions.py", line 508,   in request       resp = self.send (prep, ** send_kwargs) File "C: \ Python27 \ lib \ site-packages \ requests \ sessions.py", line 640, in   send       history = [resp for resp in gen] if allow_redirects else [] File "C: \ Python27 \ lib \ site-packages \ requests \ sessions.py", line 140, in   resolve_redirects       raise TooManyRedirects ('Exceeded% s redirects.'% self.max_redirects, response = resp) TooManyRedirects: Exceeded 30   redirects.

The code is as follows

import requests

s = requests.Session()

response = s.get(url)
