1,172 PointsI'm not sure I'm understanding the scope of this question. What am I missing?
I've added def main() like requested. There's another line that says "Everything should be in a function." Have I missed that? Isn't everything in a function?
def show_help():
# print out instructions on how to use the app
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 your current list.
""")
def show_list(shopping_list):
# print out the list
print("Here's your list:")
for item in shopping_list:
print(item)
def add_to_list(shopping_list, new_item):
# add new items to our list
shopping_list.append(new_item)
print("Added {}. List now has {} items.".format(new_item, len(shopping_list)))
return shopping_list
def main()
# make a list to hold onto our items
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(shopping_list)
continue
add_to_list(shopping_list, new_item)
show_list(shopping_list)

Treehouse TeacherHi there! I feel like you are understanding this challenge for the most part. However, there are two problems here. The first problem is that there is now a line of code that's missing completely that was there before. It's the line that calls the show_help function. I suspect that instead of writing the main function before it, you accidentally wrote it over it.
The final problem is the very last line. It isn't indented at all which means it's not inside the main function, but rather in the global scope.
Hope this helps!

def show_help():
# print out instructions on how to use the app
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 your current list.
""")
def show_list(shopping_list):
# print out the list
print("Here's your list:")
for item in shopping_list:
print(item)
def add_to_list(shopping_list, new_item):
# add new items to our list
shopping_list.append(new_item)
print("Added {}. List now has {} items.".format(new_item, len(shopping_list)))
return shopping_list
def main():
def show_help():
# make a list to hold onto our items
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(shopping_list)
continue
add_to_list(shopping_list, new_item)
show_list(shopping_list)

Treehouse TeacherHi there! Again, I believe it to be that you've altered a line that was there originally. Take a look at the first part of the original code:
show_help()
# make a list to hold onto our items
shopping_list = []
while True:
# ask for new items
new_item = input("> "
Where the original code has just show_help, you've changed it to def show_help():, which is not a call to the function but rather the beginning of a second declaration of a function inside the the new main function. Then under that, you indented everything again, which would have been correct had that been a definition of a new function.
The easiest way to have completed this challenge was to type def main(): on line 22 and then go down and indent exactly once on every single line thereafter. Here's what my main function looked like when done:
def main():
show_help()
# make a list to hold onto our items
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(shopping_list)
continue
add_to_list(shopping_list, new_item)
show_list(shopping_list)
Hope this helps!
