Hey, I'm confused on what a 'iterable' is (What does it mean?)

An interable is an object like a list, string, or tuple that contains other objects that it can return one at a time.

If you've used a for in loop, you can be said to have iterated over an object.

It seems like the challenge wants to you write a method that takes in an iterable object and return the first four things in it. So if you passed it the string "Oliver Twist", you'd get back "Oliv" and if you passed it the list [1, 2, 3, 4, 5, 6], you would get back [1, 2, 3, 4]

To iterate is a verb, in our case i think the third definition is most appropriate (taken from Dictionary.com): To operate or be applied repeatedly, as a linguistic rule or mathematical formula. Another definition is: To do something over again or repeatedly.

So an iterable is something that we may iterate over, a collection of things as stated above, lists, strings, tuples, dictionaries, sets. When using a for in loop we are iterating over our collection which is our iterable.

Think of an iterable as a collection of things that we may sort through one at a time, these collections come in different forms but they are collections nonetheless and therefore are iterables.

Thanks!
