from math import ceil, sqrt

def is_prime(n):
    if n < 2:
        return False
    if n % 2 == 0:
        return n == 2
    return all(n % x != 0 for x in range(3, int(sqrt(n)) + 1, 2))

while True:
    n = int(input("Enter a number: "))
    if is_prime(n):
        print("{} is prime.".format(n))
    else:
        print("{} is not prime.".format(n))
