Prime class has 5 methods,

1. To find nth prime
2. To check whether a number is prime or not
3. To get next prime
4. To get previous prime
5. To get all prime less than a number

All methods are stateless. Give input and get output. It't just that simple!!

from prime import Prime p = Prime()

p.nthprime(500) ## get 500th prime Output: 3571

p.isprime(23) ## check whether 23 is prime or not Output: True

p.getnextprime(20) ## Get prime after 20 Output: 23

p.getpreviousprime(20) ## Get prime before 19 __output:__19

p.getallprimes(20) ## Get all primes less than 20 Output:[2, 3, 5, 7, 11, 13, 17, 19]
