Having problems with urlparser concatenation

[i80and]

I'm working on a basic web spider, and I'm having problems with the
urlparser.
This is the effected function:
------------------------------
    def FindLinks(Website):
        WebsiteLen = len(Website)+1
        CurrentLink = ''
        i = 0
        SpliceStart = 0
        SpliceEnd = 0

        LinksString = ""
        LinkQueue = open('C:/LinkQueue.txt', 'a')

        while (i < WebsiteLen) and (i != -1):

            #Debugging info
            #print '-----'
            #print 'Length = ' + str(WebsiteLen)
            #print 'SpliceStart = ' + str(SpliceStart)
            #print 'SpliceEnd = ' + str(SpliceEnd)
            #print 'i = ' + str(i)

            SpliceStart = Website.find('<a href="', (i+1))
            SpliceEnd = (Website.find('">', SpliceStart))

            ParsedURL =
urlparse((Website[SpliceStart+9:(SpliceEnd+1)]))
            robotparser.set_url(ParsedURL.hostname + '/' +
'robots.txt')
            robotparser.read()
            if (robotparser.can_fetch("*",
(Website[SpliceStart+9:(SpliceEnd+1)])) == False):
                i = i - 1
            else:
                LinksString = LinksString + "\n" +
(Website[SpliceStart+9:(SpliceEnd+1)])
                LinksString = LinksString[:(len(LinksString) - 1)]
                #print 'found ' + LinksString
                i = SpliceEnd

        LinkQueue.write(LinksString)
        LinkQueue.close()
------------------------------
Sorry if it's uncommented.  When I run my program, I get this error:

    raise IOError(e.errno, e.strerror, e.filename)
IOError: [Errno 2] The system cannot find the path specified:
'en.wikipedia.org\\robots.txt'

Note the last line 'en.wikipedia.org\\robots.txt'.  I want
'en.wikipedia.org/robots.txt'!  What am I doing wrong?

If this has been answered before, please just give me a link to the
proper thread.  If you need more contextual code, I can post more.
