Build an Apply Discount Function

Python
1

hello can someone point out to me what is wrong in my code i already tested it and it gives the correct output but i cant pass the 3 and 4 which is determining if the price and discount is int or float.

def apply_discount(price, discount):

    if not isinstance(price,(int, float)):
        return "the price should be a number"
    if not isinstance(discount,(int, float)):
        return "the discount should be a number"
    elif price <= 0:
        return "The price should be greater than 0"
    elif discount < 0 or discount > 100:
        return "The discount should be between 0 and 100"
    else:
        discount = (discount/100)*price
        price = price - discount
    return price

print(apply_discount("100", 20))
print(apply_discount(100, "20"))
print(apply_discount(100, 101))
print(apply_discount(0, 101))
print(apply_discount(100, 20))
print(apply_discount(200, 50))
print(apply_discount(50, 0))
print(apply_discount(74.5, 20.0))
