Answer 1

Hello, I solved this today. I used a function that is not taught in the course. My first two lines of code are as follows:
order = input()
splitted = order.split(" ")

then I use an iteration to sum the prices. Hope this helps or gives you some ideas.

Answer 2

You won't benefit from the task when you let chatGPT do it.

1. There can be more than one of the same items in the input

2. You do not handle orders that are not in the menu

Answer 3

Complete the python course then go back to it.
