I am trying to copy verbatim what Kenneth is doing in this video. I am curious if there is a spacing issue that might be why this doesn't work but I can't seem to find it.
http://cl.ly/image/21120S3S2w2e this is a screen shot of my exact code...which looks a lot like his code.
This is what it is saying that I am doing wrong: http://cl.ly/image/1w220L3F2r1k Any help is appreciated.

14,335 PointsHello Brett, I saw 2 errors on the code you have showed on the image:
- On line 8, instead of shopping.list.append(item) it should be shopping_list.append(item)
- From line 22 to 26 there's an indentation error, the "elif" block, "add_to_list(new_item)" and "continue" must have the same indentation as all the code before it (I mean, the same indentation as the "if" block for example).
With this errors fixed, the code should be like this:
shopping_list = []
def show_help():
print("What should we pick up at the store?")
print("Enter DONE to stop. Enter HELP for help.")
def add_to_list(item):
shopping_list.append(item)
print("Added! List has {} items.".format(len(shopping_list)))
def show_list():
print("Here's your list:")
for item in shopping_list:
print(item)
show_help()
while True:
new_item = input("> ")
if new_item == 'DONE':
break
elif new_item == 'HELP':
show_help()
continue
add_to_list(new_item)
continue
show_list()
Hope this helps :)
