I have been using the difflib library to find where 2 large HTML documents differ. The Differ().compare() method does this, but it is very slow - atleast 100x slower than the unix diff command.
Differ compares sequences of lines *and* lines as sequences of characters to provide intra-line differences. The diff command only processes lines. If you aren't interested in intra-line differences, use a SequenceMatcher instead. Or, invoke the diff command using subprocess.Popen + communicate.
