Hi jw2013,
That's great help from you.
Your code was not working with the newest version of Leetcoe OJ.
I have updated your code and can be found at https://gist.github.com/rameshgkwd05/df5b09af01442e95607d
There is a minor updation only.

Thanks!
Ramesh

Hi all,

Seems like leetcode changed their page again, so here is updated code for this task. Let's call it Version 2016.02

Thanks for the help!

I have got a python project to save LeetCode solutions locally, too. I have just made my project compatible with latest Leetcode UI changes which happened a couple of months ago. I also started using LeetCode api wherever possible instead of relying on html contents. Here is the link to my repository. Please feel free to contribute.
