Yes, your script will be using 100% of one core, so if you have multiple cores, then the other cores won't be occupied. Your definition of a "problem" is still unclear - why shouldn't your script take 100% CPU? For a script that does a lot of CPU intensive stuff on a large input file that seems pretty normal to me.
