An iterable is a datatype that can be iterated - using a for loop. list and str are both examples of iterable datatypes.

You should create a function using the def keyword. It should be named as outlined in the challenge description. It should accept a single parameter and you should return the first four items of the iterable; slicing would indeed be an excellent way to go about that.
