Whats wrong with this code:

There are multiple issues, i'll go through the code line by line

for items in loopy:

Let me first explain how for loops work, a for loop takes a list and assigns each item to a variable within the loop, the first time through the loop the variable will be set equal to the first item in the list, the second time it will be set equal to the second, etc.

In a for loop the word following "for" is the name of the variable you want to hold the individual items in the list you provide, and the word following "in" is the name of the list.

In the above example you provide the name of the list as a variable name and the name of the function as the list name, this is wrong, a more correct example would look like this:

for item in items:

items = input('> ')

And in the above code you are overriding the variable you just defined to hold items with input from the user, the challenge never states that it is is going to provide you with any user input so this line is not necessary.

print (items) 
if items == "STOP":
  break

The challenge states that the code should stop as soon as it comes to an item that contains the string STOP, that means the if statement has to come before the print statement, otherwise the program will print "STOP" before it stops.

The correct code looks like this:

def loopy(items):
    for item in items: 
        if item == "STOP":
            break
        print (item)
