make a list that will hold on to our items

shopping_list = ['milk', 'butter', 'eggs']

def show_help(): #print out instuctions print("What should we pick up at the store?") print("""" Enter 'DONE' to stop adding items. Enter 'HELP' for this help. Enter 'SHOW' to see you current list. """) def show_list(): #print out the list print("Here's your list:")

for item in shopping_list:
       print(item)

def add_to_list(new_item): #add new items to our list shopping_list.append(new_item) print("Added{}. List now has {} items.".format(new_items, len(shopping_list)))

while True: #ask for new items new_item = input("> ")

#be able to quit the app
if new_item == 'DONE':
    break
elif new_item == 'HELP':
      show_help()
continue
elif new_item == 'SHOW':
    show_list()
    continue
add_to_list(new_item)

show_list()

Hello Ronald,

The only things I can see is that the continue in your second elif: statement needs to be indented And you need an else: statement at the end right before you call add_to_list then tab over_add_to list. Also you should be using .upper() on new_item in your comparisons if you are looking for DONE, HELP, SHOW. Otherwise, if the user enters the lowercase version of done, help, show the correct function will not run. It is best practice to either use .lower() and compare to the lowercase of what you're looking for or use .upper() and compare to the uppercase of what you're looking for. I hope this helps

Below is your code with the changes mentioned

if new_item.upper() == 'DONE':
    break
elif new_item.upper() == 'HELP':
    show_help()
    continue
elif new_item.upper() == 'SHOW':
    show_list()
    continue
else:
    add_to_list(new_item)

show_list()

Happy coding
