Answer 1

In my answer to What is a simple way to extract the list of URLs on a webpage using python? I covered that incidentally as part of the extraction step; you could easily write a method to do it on the soup and not just extract it.

from urllib.parse import urljoin

def make_links_absolute(soup, url):
    for tag in soup.findAll('a', href=True):
        tag['href'] = urljoin(url, tag['href'])

(Python 2: from urlparse import urljoin.)
