I don't see much similarity here.  While magic numbers are quite
meaningless on their own, the name prefix carries at least *some*
explanation and therefore is much less magic.  Maybe not even magic at all
in the sense of the Wikipedia article.

Except documenting what's going on and not over(ab)using the reflective
and dynamic nature of Python to the point where the source starts to get
unreadable and too magic, AFAIK there's no special "pythonic"
recommendation.  :-)
