Invalid sytax error

I'm getting the following error:

treehouse:~/workspace$ python shopping_list_3.py                                      
  File "shopping_list_3.py", line 33                                                  
    if index:                                                                         
SyntaxError: invalid syntax   

An here's my code:

shopping_list = []

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

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

print("Give me a list of things you want to shop for.")

while True:
    new_stuff = input("> ")
    if new_stuff == "DONE":
        print("\nHere's your list:")
    elif new_stuff == "HELP":
    elif new_stuff == "SHOW":
        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(
        if index:
            spot = int(index) - 1
            for item in new_list:
                shopping_list.insert(spot, item.strip())
                spot += 1
            for item in new_list:

Does anybody know what could possibly be causing this?

You need one more closing parenthesis on the input() function.
