4,433 PointsThe print("Added! ......etc") doesn't print; not sure why?
shopping_list = []
def add_to_list(item):
shopping_list.append(item)
# notify user that the item was added and state the amount left
print("Added! list has {} items ." .format(len(shopping_list)))
def show_help():
print("What should we pick up at the store?")
print("""
Enter "DONE" to stop adding items.
Enter "HELP" for this help
""")

while True:

if new_item == 'DONE':

elif new_item == 'HELP':

continue
#call add_to_list with new_item as argument
add_to_list(new_item)

Indent your add_to_list(new_item)
to be in line with the code comment above it. Code works great then.
Remember that Python is particularly picky about white space and indentation.
Happy coding.

833 PointsThanks Ken, but...shouldn't the "def add_to_list(item):" and "add_to_list(new_item)" be indented together? Like "def show_help():" and "show_help()" thanks

Treehouse TeacherYou wouldn't be adding the
new_item
to the list though if that function call is outside thewhile
statement, correct?Try adding in a
print(shopping_list)
statement at a couple of different spots in your code to see what that list contains. Then move theadd_to_list()
call inside thewhile
statement and see how it changes.Post back if you have further questions.
