how to strip the domain name in python?

[Marko.Cain.23 at gmail.com]

Hi,

I have a list of url names like this, and I am trying to strip out the
domain name using the following code:

http://www.cnn.com
www.yahoo.com
http://www.ebay.co.uk

pattern = re.compile("http:\\\\(.*)\.(.*)", re.S)
match = re.findall(pattern, line)

if (match):
        s1, s2 = match[0]

        print s2

but none of the site matched, can you please tell me what am i
missing?

Thank you.
