renumerate
==========
Reverse enumerate.
Overview
========
**renumerate(sequence, start=len(sequence)-1, end=0):**
| Return an enumerate_ object.
| *sequence* must be an object that has a __reversed__() method or supports the
sequence protocol (the __len__() method and the __getitem__() method with
integer arguments starting at 0).
| The __next__() method of the iterator returned by renumerate() returns a tuple
containing a count (from *start* which defaults to len(*sequence*) - 1 or ends at
*end* which defaults to 0 - but not both) and the values obtained from reverse
iterating over *sequence*.

`Documentation`_.
Usage
-----
.. code:: python
>>> from renumerate import renumerate
>>> seasons = ['Spring', 'Summer', 'Fall', 'Winter']
>>> list(renumerate(seasons))
[(3, 'Winter'), (2, 'Fall'), (1, 'Summer'), (0, 'Spring')]
>>> list(renumerate(seasons, start=4))
[(4, 'Winter'), (3, 'Fall'), (2, 'Summer'), (1, 'Spring')]
>>> list(renumerate(seasons, end=2))
[(5, 'Winter'), (4, 'Fall'), (3, 'Summer'), (2, 'Spring')]
Equivalent to:
.. code:: python
def renumerate(sequence, start=None, end=None):
if start is not None and end is not None:
raise TypeError("renumerate() only accepts start argument or end argument"
" - not both.")
if start is None: start = len(sequence) - 1
if end is None: end = 0
n = start + end
for elem in reversed(sequence):
yield n, elem
n -= 1
