I am using the difflib.HtmlDiff class, calling the function using two sets of text (HTML from websites), however when it makes the table

html_diff = difflib.HtmlDiff()
print html_diff.make_table(previous_contents, fetch_url.page_contents)
however that just seems to compare char by char (1 char per table row), and I end up with a 4.3MB txt file for two sets of html which are only 100k.
The doc file says, 
Compares fromlines and tolines (lists of strings) and returns a string which is a 
complete HTML file containing a table showing line by line differences with 
inter-line and intra-line changes highlighted.
however that doesn't seem to be the case.
Any suggestions?
You're supplying strings, not lists of strings (lines).
Assuming UNIX or Windows line ends:
print html_diff.make_table(previous_contents.split('\n'),
                           fetch_url.page_contents.split('\n'))
                Your answer was useful to me thank you. Do you know how we can reduce width of output diff (it shows a very wide width of both first and second file) ?

                @msashish That sounds like an unrelated question. Go ask it! If you want, you can drop me an email or message with the URL.
