returns the first four characters from an iterable. It does that in eclipse running python 3. what is the problem?

It works in eclipse. produces an iterable. My only guess is that it needs to work with strings too.

slices.py 
def first_4(first):
  return list(range(first,first+4))

first_4(1)

1 is an integer, not an iterable. The function takes an iterable, like a list, and returns the first four items from that iterable.

ok I misunderstood. I understand now. I thought it would take something that can be sequential and only take the first 4 from it. instead it wants an long list and only displays the first four of that list. Ok. Thanks!
