How to read every 100 lines from a large file : <p>How do I read every 100 lines in a larger file of around 100000 lines. I want to read every 100 lines in one iteration and make them coma seperated, run some code and next iteration, it should pick from 101 to 200.</p>

<p>I have searched internet, everywhere there is a solution for picking nth line and not n lines.</p>
