Thank you. I am copying this to tutor at python.org where a bunch of us 
hang out and collectively help others. PLEASE in future always reply-all 
so a copy goes to the list.

I am changing the subject line to something meaningful.

This sounds like a homework assignment. We don't provide answers for 
homework. We will help you once you show some effort and tell us where 
you need a hand.

The requirements are kinda vague. I would have a hard time guessing 
exactly what the instructor is looking for.

Did you get any other information?

Did you get some sample of the expected input and output?

If no th the latter,  good starting place is to write down a sample 
dialog, then apply the Python functions you should have learned by now 
to make that dialog happen.

How do you plan to store the collection of items and their prices? What 
Python data types have you learned that you could use here?

How do you plan to look up an item to get its price?

Show us your answers to any of the above, tell us exactly where you are 
stuck, and we will see what we can do to help.
