Not that dark, actually -- just a little dim. ;)
I just had it stuck in my head that every enum item would have an integer associated with it, and possibly have another
value as well.
So, for example:
--> class Constants(float, Enum):
... e = 2.81843 # am I close?
... pi = 3.141596
... tau = 2 * pi
I cannot do
and get pi. I have to do
and given the nature of floating point I can see that failing at some, er, point.
Likewise, if I have normal, but jumbled, Enum:
--> class Jumble(Enum):
... eggs = 1
... method = 'scramble'
... cost = 2.5
then to get method back I have to use
It just seems odd to me. Oh, and it would seem just as odd using __getitem__. ;)
