叫chatGPT寫段code就行了。chatgpt code見內，很clear的

def is_prime(number):

    if number < 2:

        return False

    for i in range(2, int(number**0.5) + 1):

        if number % i == 0:

            return False

    return True

 

# Example usage:

num_to_check = 1003

if is_prime(num_to_check):

    print(f"{num_to_check} is a prime number.")

else:

    print(f"{num_to_check} is not a prime number.")
