Hi Rujuta! You're almost there. If you remove the self from your last line of code it will work. Just like the method above. :)

Just wondering, why do you have "cost=10"? The code works with it in there, but I couldn't think of a reason for it. Could you please explain what you are trying to achieve by adding that in? :) Thanks.

Best,

Nakal

Thanks! that did work. So I just added the cost parameter to have an additional attribute within the new add_item function.Did not pla on using that variable as such
