Simple Linked List
Write a simple linked list implementation that uses Elements and a List.
The linked list is a fundamental data structure in computer science, often used in the implementation of other data structures. They're pervasive in functional programming languages, such as Clojure, Erlang, or Haskell, but far less common in imperative languages such as Ruby or Python.
The simplest kind of linked list is a singly linked list. Each element in the list contains data and a "next" field pointing to the next element in the list of elements.
This variant of linked lists is often used to represent sequences or push-down stacks (also called a LIFO stack; Last In, First Out).
As a first take, lets create a singly linked list to contain the range (1..10), and provide functions to reverse a linked list and convert to and from arrays.
When implementing this in a language with built-in linked lists, implement your own abstract data type.
list(), see implementing an iterator for a class.
Additionally, note that Python2's
next() has been replaced by
__next__() in Python3. For dual compatibility,
next() can be implemented as:
Note that, when trying to submit an exercise, make sure the solution is in the
For example, if you're submitting
bob.py for the Bob exercise, the submit command would be something like
exercism submit <path_to_exercism_dir>/python/bob/bob.py.

Submitting Incomplete Solutions
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
