<form name="frmLogin" method="post" action="validalogin.asp" >

I believe the ideal would be through an API, usually these services provide API's with procedures for access, ideally it would check this before. If you do not have it, try the selenium.

Selenium

An alternative would be selenium , site description (translation and free adaptation):

Selenium automates browsers. That's it! What you do with that power depends entirely on you. Primarily, to automate web applications for testing purposes, but certainly not limited to just that. Web-boring administration tasks can (and should!) Be automated as well.

Example of facebook access (just adapt to your case):

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

# Login/senha
user = "nome_user"
pwd = "senha"

# Inicializacao do driver Firefox
driver = webdriver.Firefox()

# Abrindo a pagina do facebook
driver.get("http://www.facebook.com")

# Entrada do nome do usuário / email
elmnt = driver.find_element_by_id("email")
elmnt.send_keys(user)

# Entrada da senha
elmnt = driver.find_element_by_id("pass")
elmnt.send_keys(pwd)

# Pressionando o botão de login
elmnt.send_keys(Keys.RETURN)

# Fechando o driver
driver.close()
