How do I validate sets in Python safely and idiomatically?

def validate_set(input_set):
    # Check if input is a set
    if not isinstance(input_set, set):
        raise ValueError("Input must be a set.")

    # Example validation: set should not be empty
    if not input_set:
        raise ValueError("Set cannot be empty.")
        
    # Further processing with valid set
    return True

# Example usage
try:
    my_set = {1, 2, 3}
    validate_set(my_set)  # This should pass
    
    empty_set = set()
    validate_set(empty_set)  # This will raise an error
except ValueError as e:
    print(e)
