 * **Glossary defines iterable as any object with iter() or getitem() and sequence as any object with len() and getitem(). It does not define collection.**
-* **Passing ABC Iterable to isinstance() or issubclass() checks whether object/class has iter(), while ABC Collection checks for iter(), contains() and len().**
