It is a tiny bit wasteful, since there will be another str() called on
elapsed_time. Also, it's an integer value and maybe later you want to
add those elapsed times (I'm just making this up), so it's possible
you'll remove the str() later.

Do you always convert something to a string if you the only thing
you're going to do is print it?

Also, I don't think this is clearer, keeping an int and printing it is
pretty clear :)
