I have a doubt..
can i use this *args method to handle unknown number of arguments passed to a function during the run-time??

I tend to use itemgetter because it's cleaner code than the lambda.

I'm happy with either solution. In most cases, I'd probably just use the lambda rather than itemgetter unless I knew I'd be working with a large dataset, but either way works fine. itemgetter turns out to be a little bit less expensive, time wise, and you only have to pay the import cost once, so I decided to run with that instead of the lambda.

itemgetter is always such a dilemma for it.
I like how clean and nice it is, but I almost never
use it because adding a whole import just for it feels silly,
especially since lambda x: x[n] is just as long anyway.
