shopping_list.py error '<item-name>' is not defined

I'm having this error while doing this shopping_list.py exercise:

     Traceback (most recent call last):
       File "shopping.py", line 7, in <module>
         new_item = input('> ')
       File "<string>", line 1, in <module>
     NameError: name 'Apples' is not defined

This came out after adding Apples to the list, any thoughts? Here's is my code:

    shopping_list = list()

    print("What should we pick up?")
    print("Enter DONE to stop adding items")

    while True:
        new_item = input('> ')

        if new_item == "DONE":
            break

        shopping_list.append(new_item)
        print("Added! List has {} items".format(len(shopping_list)))
        continue

    print("Here is your list:")

    for item in shopping_list:
        print(item)

ok apparently you must be using python <filename> not python3.. i.e the code relates to python 3.. there is a slight difference to how you get inputs in python2..

new_item = raw_input("please enter something: ")
