Courses Plus Student 35,157 PointsPrinting show as part of my shopping list when replicating Kenneth Love's function_list program...
Everything works great except it prints out the SHOW as a list item....what do I need to tweak to make that not happen? Thanks in advance.

Courses Plus Student 35,157 PointsSorry...yeah I guess that would help. D'oh.
shopping_list = []
def show_help(): print("What should we pick up at the store?") print("Enter DONE to stop. Enter HELP for help. Enter SHOW to see your current list.")
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 = raw_input("> ") if new_item == 'DONE': break
elif new_item == "HELP":
show_help()
continue
elif new_item == "SHOW":
print ("Here's your list: ")
for item in shopping_list:
print(item)
continue
add_to_list(new_item)
continue
show_list()

Treehouse Guest TeacherYou need to de-dent your continue inside the elif new_item == 'SHOW': block. Since it's indented inside the for loop, it doesn't skip the adding part. The continue is effectively doing nothing since it just goes to the next item in the for loop, which would happen already.

Courses Plus Student 35,157 PointsThanks...I was embarrassed and put off checking it for a few days....I re-watched your video and figured it out, as you described. Thank you very much. NJM

Treehouse Guest TeacherAww, don't be embarrassed! We also make formatting mistakes and get bit by weird loops. The more you practice and build experience, the less this will happen to you. Keep going!
