Hey Reza. Welcome to Treehouse.

Like Brendan said, the "Attach Code" isn't currently functioning, but we can break down the first part of the challenge (it's only two lines). First you need to create (def) a function that takes one arguement (can be named anything). Second return just the first 4 'parts' of the argument. If a string was passed in, it will return the first 4 letter; If a list was passed in, it would return the first 4 items; etc.

def first_4(item):     #creates the function  with one argument called 'item'
  return item[:4]     #returns the first 4 of the value passed into 'item'

Hope that helps. Keep Coding! :)

You're welcome. And, I've done that so many times, even though simple usually works best. lol. :smiley:
