with statement is used for exception handling. So it make the code cleaner and much more readable.

@rajashree-k could you please explain in detail, what exception handling you're referring to?
( I don't mind even if you write 100 lines of explanation but if you're not sure so as to why with is used, please look up on the internet).

@rajashree-k If any exception occurs in this loop, what happens to the file?

I think file will create, but if any exception occurs in the loop that time it might stops execution of the next line. Because here not used any exception handling like with, try & catch..

@rajashree-k it's obvious that the moment your code encounters a exception it would break and stop the execution of code. But the question still stands, what happens to the opened file?
