Why is my second function passing before I add the third function but not after it? Could this be a problem on Treehouse

The 2nd function was approved but after creating the 3rd function it returns this " Bummer: Didn't get the right values from first_and_last_4."

def first_4(item): listed_item = item[:] for i in item: return listed_item[:4]

def first_and_last_4(item): listed_item = item[:] first_part = listed_item[:4] last_part = listed_item[-4:] last_part.extend(first_part) return last_part

def odds(iterable): odd_numbers = iterable[:] for i in iterable: return odd_numbers[1::2]

I couldn't get your second function to pass. The console states:

AttributeError: 'str' object has no attribute 'extend'

Hmm ok, I didn't get that error message back and it did let me pass once with that method and then afterwards wouldn't accept it. It's helpful to see the error you got, I went back and added the two strings instead of trying to extend them. Thanks
