Python Introducing Lists Build an Application Add Items

Items are not appending to shopping list

shopping_list = []


def add_to_list(item):

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

show_help()

while True:
    new_item = input("> ")

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

    add_to_list(new_item)

When I add an item it keeps saying "Added! list has 0 items."

for example:

Added! List has 0 items.
> banana 
Added! List has 0 items.
> apple
Added! List has 0 items.
> orange
Added! List has 0 items.

Does anybody have an idea about what is going on with my code?

Anytime you call a method, the method name must be followed by parentheses (). This is true whether you are passing argument(s) or not.

In this case you also need to pass the item to be appended in the parentheses.
