I don't understand why this code doesn't pass

here is my code: def loopy(items): for item in items: if item != 'Stop': print item else: break

Also I tried to follow along with the shopping list code but I can't get it to run I get an exception error

breaks.py 
def loopy(items):
    for item in items:
      if item != 'Stop':
        print item
      else:
        break

Your logic is sound and other than the fact that is it looking for "STOP" and not "Stop" I honestly see no reason for your code not to work.

I am not a fan of just giving the answer but this one is strange for me so i will straight up tell you that it is looking for the reverse. Maybe someone with a deeper understanding of Python can tell us why

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

This is what it is looking for

doh! upon further investigation I stand corrected. You were 1. looking for 'Stop' instead of "STOP" AND you forgot your () around your print command. so....

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

works just fine once the typos are fixed :)

dang that was buggin me!

Thanks Shawn! That makes sense! Now I can move on. Its also weird that I cant get the shopping list to work unless I use "raw_input" instead of "input" I guess thats a python 3 thing?

Well, input() expects to read any time of variable i.e. integer number, float number, string. But in order to understand that it is a string it has to be presented with "". So for input() to work the user must provide a string "hello", but in raw_input() the user simply writes hello with no quotation marks. Hope I helped a little. :)
