I am trying to implement facebook like feature, ie, if you give a url, it extract data such as images, title and description. I know people have done it using php, jquery and ajax (http://www.99points.info/2010/07/facebook-like-extracting-url-data-with-jquery-ajax-php/) and some more also.
But because of some reasons I want to do it in python. But I am totally clueless how to start. Please help and give pointers to get started.
