Once you have the two lists, look into difflib.  E.g.,

import difflib
for i in difflib.ndiff(list1, list2):
    print i

Dan Gass has recently contributed some code that can produce 
a side-by-side difference in HTML format.  I believe it is in the 2.4
release, but you can also get it from 
"""https://sourceforge.net/tracker/?func=detail&atid=305470&aid=914575&group_id=5470"""

import difflib
tbl = difflib.HtmlDiff().make_file(list1, list2)
f = open("diffs.html", "w")
f.write(tbl)
f.close()
