Build a Discount Calculator - Build a Discount Calculator

[dlinger101]

I’m struggling with this one a little as well. My code technically meets each objective, since I can get each of the price & discount values calculated as designed, though when I input a string for either, that’s the only part that doesn’t pass the required objectives, though it does say “This should be a number” for each, but it also returns “None” afterward as well. I have looked through this thread and a couple others and I’m wondering if this leeson specifically wants us to use “type()” instead of “isinstance()” since I don’t believe we’ve learned that in the course yet.

Here’s my code:

def apply_discount(price,discount):

if not (isinstance(price, int) or isinstance(price, float)):

    print("The price should be a number")

elif not (isinstance(discount, int) or isinstance(discount, float)):

    print("The discount should be a number")

elif price <= 0:

    print("The price should be greater than 0")

elif discount < 0 or discount > 100:

    print("The discount should be between 0 and 100")

else:

    return (price - (price \* (discount / 100)))

print(apply_discount(100, 20))

print(apply_discount(200, 50))

print(apply_discount(50, 0))

print(apply_discount(100,100))

print(apply_discount(74.5, 20.0))

print(apply_discount(“five”, 20.0))

print(apply_discount(74.5, “twenty”))
