NameError: shopping_list is not defined

Hi! I'm trying to run this in my workspace and am getting a NameError in line one:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'shopping_list' is not defined

Here is my code:

shopping_list = 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('Added! List has {} items.".format(len(shopping_list)))
continue

print('Here's your list:')

for items in shopping_list print(items)

Any ideas?

If you format your code in a readable way, it'll make it easier to get your question answered!

Not sure why it posted like that:

[shopping_list = 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('Added! List has {} items.".format(len(shopping_list))) continue

print('Here's your list:')

for items in shopping_lis print(items)]

Add triple-backtick before and after your code block. Add the word python immedate after the opening triple backtick to get python coloring.

Here's your code formated below, with a few corrections:

shopping_list = 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':  #<-- missing colon
        break

    shopping_list.append(new_item)
    print('Added! List has {} items.'.format(len(shopping_list)))  #<--mismatched quote marks
    continue

print("Here's your list:") #<-- fixed conflicting single quotes

for items in shopping_list: #<-- corrected misspelled "shoppinglis"; add missing colon
     print(items)

Seems to run well now.
