iterable

> An object capable of returning its members one at a time. Examples of iterables include all sequence types (such as list, str, and tuple) and some non-sequence types like dict, file objects, and objects of any classes you define with an `__iter__()` method or with a `__getitem__()` method that implements Sequence semantics.
