Answer 1

def mask_number_with_stars_except_first_six_and_last_four(card_number):
    first_six_digits = card_number[:6]
    last_four_digits = card_number[-4:]
    
    required_mask = "*" * (len(card_number) - len(first_six_digits) - len(last_four_digits))
    
    return first_six_digits + required_mask + last_four_digits


card_number = "9003125334656789"

masked_number = mask_number_with_stars_except_first_six_and_last_four(card_number)

print(masked_number)
