Tell us what’s happening:

My 4th line for checking if discount is a int or float is not working. I did the same thing for price and it worked. Does anyone know why?

Your code so far

def apply_discount(price, discount):
    if price != int or float:
        return 'The price should be a number'
    if discount != int or float:
        return "The discount should be a number"
    if price <= 0:
        return 'The price should be greater than 0'
    if discount < 0 or discount > 100:
        return 'The price should be greater than 0'
    return price - (price % discount)

Neither of those if statements is doing what you expect.

You have two conditions here: 1) price != int, and 2) float. The or operator separates your conditions.

How can you change your second condition to get the correct result?

3

are you sure this is checking if price is of type int or float?

4

I tried using not float but it still didn’t work

5

If you just write “not float” for the second condition, how are you checking that price is not float?
