When you are not interested in some values returned by a function

Basically we don't care about the iterator value, just that it
should run some specific number of times.When you are not interested in some values returned by a function we use underscore in place of variable name .
Basically it means you are not interested in how many times the loop is run till now just that it should run some specific number of times overall.
