Konstants

Originally based on a snippit that I found years ago, but can no longer find the link. ( will be happy to give credit if someone tells me who the original author is )

Usage

MYENUMERATION = Konstants(
   K(firstconstant=0, label="first constant"),
   K(secondconstant=9, label="second constant"),
   K(thirdconstant=16, label="third constant),
)

>> MYENUMERATION[firstconstant]
0

>> # helpful for population a django ChoiceField
>> MYENUMERATION.choices()
[(0, u'first constant'),(9, u'second constant', 9), (16, u'third constant')]

>> MYENUMERATION.labels()
('first constant', 'second constant', 'third constant')

 >> MYENUMERATION.firstconstant
 0
 >> MYENUMERATION[9]
 'second constant'
 >> MYENUMERATION[MYENUMERATION.thirdconstant]
 'third constant'

9

MyENUMERATION.thirdconstant 16
