Dear Sir,

What would be the best option in learning these Programming languages like R, Perl and Python as well as Computational biology kind of things?

As I enquired for an internship I came to know that they charge 30-40K for teaching.
Kindly help.

Hello Visharajam,

If you wish to learn these languages then ideal way would be to pick one of these, refer any one online resource (there are plenty online,  like biopython cookbook) and religiously follow all pages and exercises of the same. Within 2 months you will find yourself in a very strong position. 

You can also refer O'Relly Bioinformatics Programming using Python.

A you must have got from my suggestions, my recommendation would be to put your hands on Python. There is great demand for Python experts in Bioinformatics.

Bst wishes
