'''
  Note: you must have following dependencies to run this program
        If you have pip installed, you can easily install some libraries
        like beautifulsoup4, lxml which are required for this program. 

        sudo pip install beautifulsoup4
        sudo pip install lxml

    lxml is a parser and beautiful soup uses that parser to parse webpages. 

    If you are on windows, sudo is not necessry.. :) :) :)

Since the layout in focus page changed in ravindrababuravula.com.., this program is changed accordingly. Now It will get all 300 students and group them into 5 members each

P S: As some names are removed from focus batch (from first list of candidates..), this program will exclude them as well

It's probably final update.. I think..

Make sure you download the names file too...
