Your code so far

def apply_discount(price, discount):

    if not isinstance(price, (int, float)):
        return('The price should be a number')
    elif 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:
        calc_disc = (1 - discount/100)
        final_price = price * calc_disc
        print(final_price)
apply_discount(100, 20)
apply_discount(200, 50)
apply_discount(50, 0)
apply_discount(40, 100)
apply_discount(74.5, 20.0)

Welcome to the forum @Cladvyr

Do you notice the None appearing in the console when the function is called with print?

What might cause that?

Try it out with the following print call:

print(apply_discount(100, 20))

Happy coding
