import math

def is_prime(n):
    # Check if n is less than 2 (0 and 1 are not prime)
    if n < 2:
        return False
    
    # Check for divisibility from 2 to the square root of n
    for i in range(2, math.isqrt(n) + 1):
        if n % i == 0:
            return False  # n is divisible by i, so it's not prime
    
    return True  # If no divisors are found, n is prime

# Example usage:
number_to_check = 17
if is_prime(number_to_check):
    print(f"{number_to_check} is a prime number.")
else:
    print(f"{number_to_check} is not a prime number.")
