Need help with this program, I am making a Shopping list app and for some reason it's giving me a syntax error.

shopping_list = []

def show_help(): 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 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 = input("> ")

    if new_item == "DONE":
    break
elif new_item == "HELP":
    show_help()
            continue
elif new_item == "SHOW":
            show_list()
            continue

add_to_list(new_item)

show_list()

shopping_list = []

def show_help(): 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 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 = input("> ")

    if new_item == "DONE":
    break
elif new_item == "HELP":
    show_help()
            continue
elif new_item == "SHOW":
            show_list()
            continue

add_to_list(new_item)

show_list()

File "shopping_list.py", line 17 def show_list(): | SyntaxError: invalid syntax

Why does my function have a syntax error? Thanks!

Try formatting your code so the spacing shows up (in Python, indentation is everything).
Use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. :arrow_heading_down:
Or watch this video on code formatting.

Once you've edited this question so the code is formatted, it will be much easier for someone to help.

It's very hard to read unformatted, but I may have spotted the issue anyway. It looks like you may have unbalanced parentheses here:

     print("Added! List has {} items.".format(len(shopping_list))

I see 3 opens but only 2 closes.
