List Only Showing Last Item Entered In All Spots Created

Shopping List Take 3.

Only the last item I entered appears on the final lists.

shopping_list = []

def show_help():
    print("\nSeparate each item with a comma.")
    print("DONE to quit, SHOW to see current list, HELP to get this message.")

def show_list():
    count = 1
    for itme in shopping_list:
        print("{}: {}".format(count, item))
        count += 1

print("Give me a list of things you want to get or do.")
show_help()

while True:
    new_stuff = input("> ")

    if new_stuff == 'DONE':
        print("\nHere's your list:")
        show_list()
        break

    elif new_stuff == 'HELP':
        show_help()
        continue

    elif new_stuff == 'SHOW':
        show_list()
        continue

    else:
        new_list = new_stuff.split(", ")
        index = input("Add this at a certain spot? Press enter for the end of the list, "
                      "or give me a number. Currently {} items in the list.".format(len(shopping_list)))

        if index:
            spot = int(index) - 1
            for item in new_list:
                shopping_list.insert(spot, item.strip())
                spot += 1
        else:
            for item in new_list:
                shopping_list.append(item.strip())

You have a typo in show_list()

def show_list():
    count = 1
    for itme in shopping_list:  # <--should be 'item' not 'itme'
        print("{}: {}".format(count, item))
        count += 1

Why does the code still work? Because item is defined in the global namespace. show_list is just using the last known value.
