I need you to help me finish my loopy function. Inside of the function, I need a for loop that prints each thing in item

I need you to help me finish my loopy function. Inside of the function, I need a for loop that prints each thing in items. But, if the current thing is the string "STOP", break the loop.

Cant seem to get this one.

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

It can be frustrating sometimes when you can't get past the challenge. I did the conditional first and THEN print(thing). Hope that helps!

Try this.

def loopy(items):
    for i in items:       #  Start loop assigning each item to i
        if i == "STOP":   #  Check to see if i is "STOP"
            break         #  If it is, break out of the loop
        else:             #  Otherwise...
            print(i)      #  Print i

Hi Jamal,

You are very close to the answer, here is how I did it: 

def loopy(items):
    # Code goes here

    for loopy in items:
        print(items)

Why are you learning Python? Maybe we have the same aims! I am learning it to bring my Start UP www.wolf-gate.com to the next level. Thank´s to Kenneth Love it´s easily possible :)

Yep. Definitely helps to think of the items argument being a list rather than a single string.

Even though this is the correct answer. Could someone explain why the loop doesn't actually break when you enter the string STOP in the function. After the function has been defined and run, when you actually type in loopy("STOP") the for loop doesn't actually break, instead it runs through each of the elements in the string and prints them out as:

S T O P

This is the same as what happens when you enter in another word for items such as loopy("apples") you get: a p p l e s

Shouldn't STOP completely break the for loop instead of printing out the elements of STOP?

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



list = ['apples', 'pears', 'STOP', 'peaches', 'beer']

loopy(list)

So I made a list to give you a better idea of what the loopy function is doing. Then I called loopy with my list as an argument. Because list has 'STOP' in it, loopy will break. If you were to run this in python, you would see it only prints apples, and pears before breaking the loop. Does that help?

not sure if this is correct Python language, but this is what solved the first part of the challenge for me:

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

I'm stuck. I tried this

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

and this

def loopy(items): for thing in items: print thing

nothing works.
