iOS Development Techdegree Student 3,775 PointsCode follows the video, yet I still get errors.
I've typed the code along with Kenneth in the video, yet for some reason I can't get the code to run correctly.
Here's my code: shoping_list = []
def show_help(): print("what should we pick up at the store?") print("Enter DONE to stop.")
def add_to_list(item): shopping_list.append(item) print("Added! List had [] 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": show_list() break add_to_list(new_item) continue
show_list()
and the output error I get is this:
DONE
Here's your list:
Traceback (most recent call last):
File "shopping_list.py", line 23, in <module>
show_list()
File "shopping_list.py", line 15, in show_list
for item in shopping_list:
NameError: name 'shopping_list' is not defined

iOS Development Techdegree Student 3,775 PointsI think my issues were a combination of both those things:
I cleaned up the white space and checked a couple indents, and corrected my spelling error in the beginning. The code is now running like butter.

iOS Development Techdegree Student 3,775 PointsGreg, I'm glad you clarified that. I had some really confusing moments with that. Ha.

39,021 PointsHi Henry,
White space is important in Python, so it would be helpful if you wrapped your code in tags like this:
```Python
[All your code]
```
If you do this, your code will be formatted appropriately!
