What's the problem with my code

I have followed the instruction:

  1. create a function called "first_4"
  2. return the first 4 item
slices.py 
def first_4(iterable):
    return iterable[0:3]

Hi Chi,

The stop value is not included when you do a slice in Python (that, and the first value would be at 0... thus, you're returning items 0, 1, 2 and 3, which are the first four items of the iterable), so the challenge is actually looking for:

def first_4(iterable):
    return iterable[0:4]

Hope this helps!
