[Tutor] continuous running of a method

[Nitin Das]

The problem with this while loop is if your random value doesn't lie between
the mentioned range then ur 100% cpu would be utilized. The one thing u can
do is to sleep for some time lets say 0.5 sec after every while loop
iteration , in this case ur cpu utilization will go down.
