How do I finish this loop?

I wrote this in "Workspaces" first and it seems to work there, but it is not correct for the challenge task. What am I doing wrong?

items = []

def loopy(items):

    print("What things are in items?")
    print("Enter 'STOP' to finish adding things.")

while True:

    thing = input("> ") 

    if thing == "STOP":


print("Here are your items:")

for thing in items:

Hi Benjamin - For the challenges try to follow the instructions closely and avoid adding code that is not asked for. Here you only need a for loop, just like the one you have at the bottom of your code. Then inside the loop start with an if statement to see if the current item is "STOP". If it is break, again very similar to the if statement you have in your code. Then after the if statement print the current item in the loop. Also, items is passed into the function so don't define it in your code. Hope this Helps.
