I'm getting a NameError unless my input is typed as a String. Even when I copy & paste the exact same code in video

code :shopping_list = []

print("What should we pick up at the store?") print("Enter 'DONE' to stop adding items.")

while True:

new_item = input("> ")

if new_item == 'DONE':
    break

shopping_list.append(new_item)

print("Here's your list:")

for item in shopping_list: print(item)

Hi Ross,

It sounds like you are using Python 2. If so, you will need to use the raw_input() function instead.

input() does not work the same in Python 2 as Python 3.

I would recommend using Python 3 while following along in these courses.

Thanks Ryan, big noob error on my part. I'm using a python 2 interpreter to read python 3 code!
