Hi everyone. I have an idea which is add a new feature to enumerate(iterable, start=0) built-in function. I mean, "start" is ascending by default, we can add a feature to this function to change start in descending order.
for example:
enumerate(iterable, start=100, reverse=True)
reverse: If True, the start is reversed.
(100, iterable[0]), (99, iterable[1],), and so on.

This has nothing to do with the parser so I'm removing the label. Please, next time make sure you select the appropriate categories when opening an issue

Thank you for the suggestion, but we will decline.  We looked at this before and decided not to go down this path, preferring instead to the keep the builtin function simple and focused on its core task of enumeration.

To cover the rarer cases, it is a simple matter to fulfill the need with fast, clear code using itertools:

>>> from itertools import count
>>> names = ['eddard', 'catelyn', 'robb', 'sansa', 'arya', 'bram', 'rickon']
>>> for i, name in zip(count(start=7, step=-1), names):
        print(i, name)

7 eddard
6 catelyn
5 robb
4 sansa
3 arya
2 bram
1 rickon
