I also tried this for discount:

    if (discount is not int) or (discount is not float):
        return 'The discount should be a number'
22

it also didn’t work sadly

23

why are you using a different method here for price and for discount?

24

this is the most recent code:

def apply_discount(price, discount):
    
    if (price is not int) or (price is not float):
        return('The price should be a number')
    if (discount is not int) or (discount is not float):
        return 'The discount should be a number'
25

so you decided on this method? is it working? have you tested it?
have you tested the other method?

26

This is wrong it does not work:

This is correct:

Can you see the difference? Test it!

27

ok I’ll test it and see if it works

28

but also what I have currently for the price detection works so I’m still gonna see if it’ll work

29

Do not test the full code.

Erase everything (or use a different editor https://www.online-python.com/) and test one statement at a time.

I tested this and it didn’t work:

def apply_discount(price, discount):
    a
    if(isinstance(discount, int)):
        return('The discount must be a number')
    if(isinstance(discount, float)):
        return('The discount must be a number')
31

the a is to avoid an error

32

now that I realize it the a is useless

33

so here is the same code without the a:

def apply_discount(price, discount):
    if(isinstance(discount, int)):
        return('The discount must be a number')
    if(isinstance(discount, float)):
        return('The discount must be a number')
34

and it still failed the test

35

So, if the discount is an integer you want to return “The discount must be a number” ?

It seems like an integer IS a number

I’ll answer any questions you have and help you but in the end you have to write this code and figure it out.

36

I see the mistake now thank you for pointing it out

37

edited and it still doesn’t want to pass that test

def apply_discount(price, discount):
    if(isinstance(discount, int) is False):
        return('The discount must be a number')
    if(isinstance(discount, float)is False):
        return('The discount must be a number')
38

consider what happens if it a float to isinstance(discount, int)
consider what happens if it is an int to isinstance(discount, float)
