retrieving real time quotes from yahoo

[ss]

Hello,
ive started using python for a few weeks now, and came across a
problem that i would appreciate help solving.  im trying to create
code which can grab real time quotes from yahoo (yes ive created an
account for yahoo finance).  But im not sure how to generate an
authenticated login and how to request data.  Ive been searching the
net for over the last few hours without having found a way to do this.

any help  would be welcome

thanks!
