traversing yahoogroups group messages

i want to traverse a set of messages in a Yahoogroups group from a Python
program.

to get to the messages of the group, one must log in.

this presents, i think, two problems,
1) handling the form element for the login, which has a javascript submit
routine,
2) keeping login state with cookies.

to someone who knows something about the issues here, my questions are:

1) is it possible to do this in Python?
2) if so, how do i handle the form and the javascript?
3) does Java Python have a javascript engine and do i need Java Python here?
4) if i need to use cookies, how do i know what to name and what to set into
a cookie?

for context, i include the form element below.
the submit routine hash() is javascript.









<form method=post
action="https://login.yahoo.com/config/login?ej1cd3h7oogel" autocomplete=off
name=login_form onsubmit="return
hash(this,'http://login.yahoo.com/config/login')">
