Well, I didn't include anymore code because it was really trivial, and I thought the problem could be found from the 
exceptions. However, since you asked, I'll paste the code in as well.

from urllib import urlretrieve
from string import strip

def firstnonblank(lines):
    for eachLine in lines:
        if strip(eachLine) =='':
            continue
        else:
            return eachLine

def firstlast(webpage):
    f = open(webpage)
    lines = f.readlines()
    f.close()
    print firstnonblank(lines),
    lines.reverse()
    print firstnonblank(lines),

def download(url = 'http://www.opera.com:3600',process = firstlast):
    print url
    retval= urlretrieve(url)[0]

    if retval:
        process(retval)

def urlEntry():
    url2 = raw_input('Please enter the URL')
    download(url2,firstlast)
    
if __name__ == '__main__':
    download()


The error, as stated before, occurs on the call to urlretrieve(), and the exception is as follows:

Traceback (most recent call last):
  File "C:\Program Files\Python20\Pythonwin\pywin\framework\scriptutils.py", line  301, in RunScript
    exec codeObject in __main__.__dict__
  File "C:\Program Files\Python20\scripts\grabweb.py", line 37, in ?
    download()
  File "C:\Program Files\Python20\scripts\grabweb.py", line 23, in download
    retval= urlretrieve(url)[0]
  File "C:\PROGRA~1\PYTHON20\LIB\urllib.py", line 68, in urlretrieve
    return _urlopener.retrieve(url, filename, reporthook, data)
  File "C:\PROGRA~1\PYTHON20\LIB\urllib.py", line 198, in retrieve
    fp = self.open(url, data)
  File "C:\PROGRA~1\PYTHON20\LIB\urllib.py", line 166, in open
    return getattr(self, name)(url)
  File "C:\PROGRA~1\PYTHON20\LIB\urllib.py", line 267, in open_http
    h = httplib.HTTP(host)
  File "c:\program files\python20\lib\httplib.py", line 640, in __init__
    self._conn = self._connection_class(host, port)
  File "c:\program files\python20\lib\httplib.py", line 330, in __init__
    self._set_hostport(host, port)
  File "c:\program files\python20\lib\httplib.py", line 336, in _set_hostport
    port = int(host[i+1:])
ValueError: invalid literal for int():

Hopefully this is enough information now, and thank you to anyone who's looking at this.
