This script determines if a whole number is prime or composite.


# Define a function to check if a number is prime
def is_prime(n):
    # Check if n is numeric and a whole number
    if not isinstance(n, (int, float)) or n != int(n):
        return "Invalid Input"
    
    n = int(n)  # Convert safe floats like 7.0 to int
    
    if n < 2:
        return "Invalid Input"
    
    for i in range(2, int(n**0.5) + 1):
        if n % i == 0:
            return "Composite"
    
    return "Prime"
