[Tutor] Beautiful soup

[paul brian]

How did you change it to look at the file on your PC?
You appear to have told urllib2 to use "FRE_word_list.htm", it cannot
find that online so tried to look for it on your local disk at
'\\C:\\Python24\\FRE_word_list.htm

I would suggest that you either put your local html on a web server
and send in that local URL or replace html =
urllib2.urlopen(url).read() with
html = open(r'c:\myfolder\myfile.html').read()  and see where that takes you.

cheers
