So you have this:

> * * log.write(site + "\n")

So now:

site = "http://" + ""

Hmmm...let's see what happens when I run the following program:

import urllib

site = "http://" + ""
html = urllib.urlopen(site)

Traceback (most recent call last):
File "", line 4, in ?
html = urllib.urlopen(site)
File "/Library/Frameworks/Python.framework/Versions/2.4//lib/
python2.4/", line 82, in urlopen
File "/Library/Frameworks/Python.framework/Versions/2.4//lib/
python2.4/", line 190, in open
return getattr(self, name)(url)
File "/Library/Frameworks/Python.framework/Versions/2.4//lib/
python2.4/", line 303, in open_http
h = httplib.HTTP(host)
File "/Library/Frameworks/Python.framework/Versions/2.4//lib/
python2.4/", line 1097, in __init__
self._setup(self._connection_class(host, port, strict))
File "/Library/Frameworks/Python.framework/Versions/2.4//lib/
python2.4/", line 586, in __init__
self._set_hostport(host, port)
File "/Library/Frameworks/Python.framework/Versions/2.4//lib/
python2.4/", line 598, in _set_hostport
raise InvalidURL("nonnumeric port: '%s'" % host[i+1:])
httplib.InvalidURL: nonnumeric port: ''
