Stuck at this question - error message, not supposed to use while loop as well?

Here's my stab at it:

def loopy(items): # Code goes here items = [] while True: new_items = input(" ")

                for new_items:
                        print(items)

Am not supposed to involve a while loop?

breaks.py 
def loopy(items):
    # Code goes here
    items = []
            while True:
            new_items = input(" ")

                    for new_items:
                            print(items)

These and later challenges are tested using an automated checker that will call the function with various values assigned to items. The is no need to use a while loop or use the input() function. Your code is also resetting the input value back to an empty list. Removing these statements leaves you with:

def loopy(items):
    # Code goes here
    #items = []
    #while True:
    #    new_items = input(" ")

    for new_items:
        print(items)

This is closer. Now the for loop syntax is incorrect.

    # loop over the items
    for item in items:
        print(item)

Post back if you need more help. Good Luck!!

Hi there, Chris, thanks for your response, if I cut out the while loop and the input, I think I would just use:

def loopy(items):
    # Code goes here
      for item in items:
            print item

but that still gives me a generic 'Bummer, Try again' error message.
