quick regex question

[Xx r3negade]

Hi, I am very bad with regexes.
I need a regular expression that will reduce a url like this:

hxxp://example.com/somefolder/something/whatever

to its base:

hxxp://example.com

The two slashes after the http: complicate things. I know I could just remove the "http://" and add it again later, but as a learning experience, I would like to do this regex in a single line.

Thanks in advance

erm..

import re
p = re.compile(r'http://.*?\.(com|co\.uk)')

you can obviously adjust the end to add as many different domains as you can think of.

The re solution may depend on the different possibilities of the URL name. Here is one possible solution:

import re
 
patt = re.compile(r'([a-z]+?:/+?\w+?\.\w+?)/')
 
m = patt.match("hxxp://example.com/somefolder/something/whatever")
if m:
     print m.group(1)
