    PASSWORD = "xxxx"
    LOGIN_URL = "http://ift.tt/UD1D8M"
    URL = "http://ift.tt/1NnEDO7"
    session_requests = requests.session()
    result = session_requests.get(LOGIN_URL)
    tree = html.fromstring(result.text)
    payload = { "LoginForm[email]": USERNAME,  "LoginForm[password]": PASSWORD, }
    result = session_requests.post(LOGIN_URL, data = payload, headers = dict(referer = LOGIN_URL))
    result = session_requests.get(URL, headers = dict(referer = URL))
    tree = html.fromstring(result.content)
    bucket_elems = tree.findall(".//<td[@class='&gt;']")
    bucket_names = [bucket_elem.text_content().replace("\n", "").strip() for bucket_elem in bucket_elems]
    print bucket_names

I have no idea how to do it
