The main task is to constitute a correct URL.
e.g. the requested page is www.somepage.com,
first input form'id is input1, and respectively.

The request URL should be
'www.somepage.com?input1=value1&input2=value2',
post it and you'll get the response page .

Just do:

import urllib

value1=getValue1()
.
.
.

url='www.somepage.com?input1='+str(value1)+'&input2='+str(value2)
resp=urlopen(url)
parseResp(resp)

Problem: if the authentication code is an image, how to deal with it?

:)Sorry for my poor english.
