You need a few things. First, learn files. Once you know files, you need
to

import urllib
filename =
urllib.urlretrieve("http://www.weather.com/weather/local/XXXXX")

(except that that all goes on the same line--hopefully that won't
autowrap on me) (where XXXXX is your zip code)

filename is a tuple with two components; the 0th is the location of the
file, and the second is a mimetools.Message, which I have no idea how to
use. so you can

thefile = open(filename[0], 'r')

and then 

currentline = thefile.readline()

until you see text like "insert current temp" or "insert forecast text"
(look at the raw text file, and you'll understand what I mean) and you
can pluck the relevant information out of those lines. DO NOT expect
your temperature to always be a number; sometimes it will be "N/A".

good luck. Don't know if that was basic; you have a relatively
complicated task for a "first time programming" type thing.
