Python Introducing Lists Build an Application Display the List

IF / ELIF statement

So as we check new_item to see if it matches DONE, SHOW, or HELP, I've been doing it as shown below.

if new_item.upper() == "DONE":
    break

elif new_item.upper() == "HELP":
    show_help()
    continue

elif new_item.upper() == "SHOW":
    show_list()
    continue

Is there any downside to this, or is it just personal flavour? My reasoning behind it is if they do it lower case or in weird casing, but does this open me up to bugs further down the road? I've tested it by adding things like: 'TV SHOW' and 'well done roast beef' and it seems fine.

i would add the upper() method to the input() to avoid bugs in the future, like so :

new_item = input("> enter command: ").upper() if new_item == 'DONE': break

Making command words case-insensitive is a common practice, and a nice enhancement to the project. :+1:
