Given a positive integer $n,$ assign True to is$\_$prime if $n$ has no factors other than $1$ and itself. $($Remember$,m$ is a factor of $n$ if $m$ divides $n$ evenly.$)$

Instructor Notes:

if an integer is divisible by any integer smaller than itself $($other than $1)$ you can immediately set is$\_$prime to False and break the loop
