Help to complete the code

the nomad (2)
The assignment: To write a program that accepts the user's order and print the total cost of the order including tax or a message that says "Sorry, we do not have that product". Use dimensional variables to save the products and cost.

I wrote a code that input the products and price into ta file, then it gives me the list, but I have no idea what is a dimensional variable and how does the user selects only few products, total the purchase, plus add tax for a grand total.

Here is what I have so far
