Python Introducing Lists Build an Application Add Items

Question about Program - Don't get the number of items to show

Hello. The script runs, but does not return the number of items.

# Create a new empty list called shopping_list
shopping_list = []

# Create a function named add_to_list that delcares a parameter named item
  # Add the item to the list
def add_to_list(item):
    # Notify user that the item has been added, and state the number of items in the list currently
    print("Added:list has {} items".format(len(shopping_list)))

def show_help():
  print("What should we pick up at the store?")
Enter 'DONE' to stop adding items
Enter 'HELP' for this Help


while True:
  new_item = input(">")

  if new_item == 'DONE':
  elif new_item == 'HELP':

    # Call add_to_list with new_item

[MOD: added ```python formatting -cf]

The add_to_list(new_item) is inside the elif block, and after the continue statement. Hence, it will never be reached. Unindent the line and it should work.

Post back if you need more help. Good Luck!

Thank you very much.

I have the same problem and when I changed the indent it still didn't work

Please your current code as a comment to this post.

I am having this same issue. I unindented the call as suggested and that did not resolve the problem.

I suggest posting your code in a new forum question. Feel free to tag me in the post.

unindent just after the while statement.
