shopping_list=[] new_item="" x=1
def show(): print(shopping_list)
def helpMe(): print("Special Commands are SHOW,DONE,and HELP")
new_item=input("Add an item to your list, or type DONE: ")
while new_item != "DONE": if new_item=="DONE": print(shopping_list); break
elif new_item=="SHOW":
show()
continue
elif new_item=="HELP":
helpMe()
continue
else:
shopping_list.append(new_item);
new_item=input("Add another item or type DONE: ");
for item in shopping_list: print (">"+item)
whenever you type in SHOW or HELP, code enters infinite loop, ignores continue no idea why

Since you input before the loop, then the loop will continue to perform the selected function infinitely.
Move the input function inside the loop so you can get a fresh user command for each iteration.

5,708 PointsYes, Steven is right. I would suggest going back over the video and completing the lesson, line by line, and word for word so that you get the hang of the formatting and syntax as I did. That will give you the feel for what Kenneth wants us to understand. You can then go back and put your own spin on the app if you want.
shopping_list=[] new_item="" x=1
def show(): print(shopping_list)
def helpMe(): print("Special Commands are SHOW,DONE,and HELP")
new_item=input("Add an item to your list, or type DONE: ")
while new_item != "DONE": if new_item=="DONE": print(shopping_list); break
This does not appear to be formatted properly; see my example below.
shopping_list[]
while True:
new_item = input("> ")
Start there...

229,732 PointsWhat does the "shopping_list[]" line do, and why would the "while" line be indented more?

Thanks ;-)
