urllib2 is the standard library in 2.7.3 to use, in 3.3 it is urllib
straight from the doc page

import urllib2
f = urllib2.urlopen('http://www.python.org/')
print f.read(100)
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<?xml-stylesheet href="./css/ht2html

And so your journey begins.  With recursing into links, etc., etc.

Also since you're new you may want to work with python3 but not
a requirement.

There are lots of free books online, search this list for links.
(you can search this list at gmane and probably elsewhere)
