[Tutor] Python Version of "enum" ?

[McLaughlin, Toby]

Perhaps this:

"Unpacking assignment also gives rise to another common coding idiom in
Python: assigning an integer series to a set of variables:

>>> red, green, blue = range(3)
>>> red, blue
(0, 2)

This initializes the three names to integer codes 0, 1, and 2,
respectively (it's Python's equivalent of enumerated data types you may
have seen in other languages)."
