Make a function named first_4 that accepts an iterable as an argument and returns the first 4 items in the iterable
def first_4(list_1):
return list_1(0:4:1)

Treehouse Moderator 68,423 PointsYou are very close. Replace the parens with square brackets:
def first_4(list_1):
return list_1[0:4:1]
Since the default step is 1 and the default start is 0, the slice can also be written as:
return list_1[:4]
As written in your post using parens, it means call a function named list_1() with the argument [0:4:1]. This is invalid syntax for an argument and the function list_1 does not exist.
