Answer 1

newlink = link['href']
# .. make replacements
link['href'] = newlink # store it back

Now print(soup.prettify()) will show changed links. To save the changes to a file:

htmlDoc.close()

html = soup.prettify("utf-8")
with open("output.html", "wb") as file:
    file.write(html)

To preserve original character encoding of the document, you could use soup.original_encoding instead of "utf-8". See Encodings.
