How to store an instance variable in an array

Hey everyone!

items = "milk"

grocery_list = [milk]

grocery_list ...returns... "milk"

Why is that? Why isn't the instance variable items stored in there, instead of the value?

Thanks in advance

Please explain. I'm not sure I understand the question when confronted with the code. If grocery_list = ["milk"], then grocery list only has one item with index [0] and value "milk". You didn't put items` variable anywhere, so you can't expect it to be anywhere.
