Why ?
def first_4:
a = list(range(20))
items = a[:4]
return items
first_4()

But your function needs to take in "a" as a passed argument instead of creating it yourself using range. Just fix that and you'll pass.
Also, you only need to define the function, not call it.

Treehouse TeacherHi, Robert! I've removed the content of your answer as no explanation for how or why the code works was provided. Feel free to resubmit your answer with an explanation. This will provide the original poster with a better learning experience. Thanks!

Treehouse TeacherHi there! Just because it passes a challenge does not mean that the code is necessarily correct. The opposite is also true. Fully functional code may not pass a challenge because it doesn't meet a specific requirement. The challenge does not require a loop, and Steven is correct. Once a return statement is hit, the function exits meaning that it will only ever do one iteration. Also, in your code, you have (by necessity for a for loop) a variable named iterables
which is never used other than to start the iteration.
Treehouse does discourage the posting of an explicit answer without any explanation as to how or why the code works. Could you please update your answer to include an explanation? Thanks!
