Steve,
It looks like what you're trying to achieve is an Enum with more than a
singleton `.value` exposed on each sub-item.
I was able to achieve something that *looks* like your example using an Enum
mixin with a custom class:
> from enum import Enum
class Labeler:
@property
def label(self):
return self.name.capitalize()
class Size(Labeler, Enum):
SMALL = "S"
MEDIUM = "M"
LARGE = "L"
Size.LARGE.label
'Large'
Size.LARGE.value
'L'
More custom values could be added by expanding `Labeler`.
FWIW, I also got a mixin with namedtuple to work:
> from collections import namedtuple as nt
Key = nt('Key', ('label', 'value'))
class Foo(Key, Enum)
Bar = Key(label='Cat', value=5)
Baz = Key(label='Dog', value=10)
Foo.Bar.label
'Cat'
These both were with Python 3.7.
