How to use the for loop to print out item? And what does the question mean? How do I "Break"?

I don't quite understand the question on for loop and break.

breaks.py 
def loopy(items):
    # Code goes here

You have to use a for loop to "see" every item in that variable "items" which is the variable that you have received as an argument. Inside that for loop you have to check if the current thing is equal to the string "STOP", if that is true you have to break out of the loop, other wise you have to print the thing. You could do it like this:

def loopy(items):
    # Code goes here
    for thing in items:
        if thing == "STOP":
            break
        print(thing)

I hope that helps a little bit

What about the word "thing" is that just a word for computer to know there is something there?

The for loop is used to check/see every item inside of an iterable. In order to do that you have to use a variable that is going to hold the current item of that iterable that you're checking. You can use any name, "thing", "item", anything that represents the current "thing" in the iterable.

for item in items:
    print(item)

I hope that helps a little bit.
