Append function doesn't work / list returns empty

[KIBautista]

When I run through the program and enter items, they do not show up in the end when you enter "show" to return the list. Could anyone help with how to fix that issue?

Hello! I believe it's an indentation error. Python uses indentation to delineate blocks of code, so your main loop should look like this to get the desired functionality (I added | pipe characters to illustrate the indentation):

while True:
    new_item = input("> ")
    |
    if new_item == 'DONE':
    |   break
    elif new_item == 'HELP':
    |   show_help()
    |   continue
    elif new_item == 'SHOW':
    |   show_list()  # <-- These two lines are under-indented
    |   continue     # <-- Should be 4 spaces
    |
    add_to_list(new_item)  # <- needs to be in-line with rest of 'while' block

It might also be better to add an explicit else statement like

    else:
        add_to_list(new_item)

to be clearer about the control flow. I hope this helps!
