flag = False

# prime numbers are greater than 1

if num > 1:

   # check for factors

   for i in range(2, num):

       if (num % i) == 0:

           # if factor is found, set flag to True

           flag = True

           # break out of loop

           break

# check if flag is True

if flag:

   print(num, "is a prime number")
