get_help() function is not being called in my main function

So I'm on the shopping list app, and it wants me to put all the code in the main function.. I've indented everything and it claims it is not getting the call correctly

def show_help():
    # print out instructions on how to use the app
    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 current list.
    """)

def show_list(shopping_list):
    # print out the list
    print("Here's your list:")

    for item in shopping_list:
        print(item)

def add_to_list(shopping_list, new_item):
    # add new items to our list
    shopping_list.append(new_item)
    print("Added {}. List now has {} items.".format(new_item, len(shopping_list)))
    return shopping_list

def main ():
    show_help() # Says that this isn't displating... although it is clearly right here.

    shopping_list = []

    while True:
        new_item = input("> ")

        if new_item == 'DONE':
            break
        elif new_item == 'HELP':
            show_help()
            continue
        elif new_item == 'SHOW':
            show_list(shopping_list)
            continue
        add_to_list(shopping_list, new_item)

    show_list(shopping_list)

Good evening,

This one is working for me fine:

 def show_help():
    # print out instructions on how to use the app
    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 current list.
""")

def show_list(shopping_list):
    # print out the list
    print("Here's your list:")

    for item in shopping_list:
        print(item)

def add_to_list(shopping_list, new_item):
    # add new items to our list
    shopping_list.append(new_item)
    print("Added {}. List now has {} items.".format(new_item, len(shopping_list)))
    return shopping_list

def main():
    show_help()
    # make a list to hold onto our items
    shopping_list = []
    while True:
        # ask for new items
        new_item = input("> ")
        # be able to quit the app
        if new_item == 'DONE':
            break
        elif new_item == 'HELP':
            show_help()
            continue
        elif new_item == 'SHOW':
            show_list(shopping_list)
            continue
        add_to_list(shopping_list, new_item)
    show_list(shopping_list)

But I did not spot any differences except one, you left out those comments, they have put in. Maybe that's the problem. You could keep me up to date, if that helped you.

I re entered my original code and it seemed to take it. I'm unsure what was causing it to object to it but I didn't change anything! Thanks.

Ok, That's cool, that it works now:)
