first_4("hi", "there", "man", "tier", "cart")

first_4("hi", "there", "man", "tier", "cart")
This call has 5 arguments.
<p>
The line below is one argument array with 5 elements in it.
first_4(["hi", "there", "man", "tier", "cart"])
It will return: ['hi', 'there', 'man', 'tier']
If properly implemented. <p/>
String is also iterable so you could pass this to your function:
first_4("hi there man tier cart")
Result: 'hi t'
I hope it helps.

1,633 PointsWithout giving a solution I will tell you that this is literally one line function. Slicing is smart enough to account that your object may not be long enough to have 4 elements.
Also, drop the asterisk from function definition.
Respond back if you are unable to proceed.

What about odds def odds(arg): return arg[::2]
should return odd indexes and it passes in my console, but not the quiz console
Kenneth Love
Treehouse Guest TeacherExcept the problem is to return items with an odd index. [::2] will return indexes [0, 2, 4, 6, 8, ...].
