The output must be formatted with a title and the prime numbers must be printed in 5 properly aligned columns . I have used this code so far :

>         elif potentialprime % divisor == 0:

>             break
>         while potentialprime % divisor != 0:
>             if potentialprime - divisor > 1:
>                 divisor += 1
>             else:

>         potentialprime += 1
