I haven't used continue, is it necessary? my code works just fine without it...

list_items = []
def show_help():
    print("""Type "HELP" to see the available functions,
Type "SHOW" to show the current items on the list
Type "DONE" to quit the programme""")

def add_item(list_item):
    list_items.append(list_item)

def print_list(list):
    print("Current Items: ")
    for items in list:
        print(items)

def function():
#1*Run the script to start using it
    show_help()
    item = ""
    while item!="DONE":
        item = input('Add a task to be done: \n')
    #2*Enter the word DONE in all caps to quit the programme    
        if item=="DONE":
    #4*One I quit, I want the app to show me everything that's on my list
            print_list(list_items)
            break
        #5I should be able to type "SHOW" to show what's current on the list
        elif item=="SHOW":
               print_list(list_items)
        #6I should be able to all the functions such HELP, DONE and SHOW by typing "HELP"
        elif item=="HELP":
            show_help()
        else:
    #3*put new things into the list, one at a time
            add_item(item)

function()
