How to get spesific index number, name and price from food listof ?
I already tried but i got full object like this foodInfo(name=Pizza, price=50000)
As far as I could understand your question, this could be a possibility of printing the index of the item
Since Lists use 0-based indexing,
index+1
could help you print the exact index. I've just put a hint in the right direction for you
