The way I organize my choices on my Django Projects.

choices_enum.py

class ChoicesEnum(object):

    @classmethod
    def choices(cls):
        descriptions = cls.get_descriptions()
        keys = descriptions.keys()
        attrs = cls.get_atributes(keys)
        return tuple([(attrs[k], descriptions[k]) for k in keys])

    @classmethod
    def get_descriptions(cls):
        description = {}
        for attr, val in cls.__dict__.iteritems():
            if attr.lower().endswith('_text'):
                description.update({attr[:-5]: val})
        return description

    @classmethod
    def get_atributes(cls, keys):
        attrs = {}
        for attr, val in cls.__dict__.iteritems():
            if attr in keys:
                attrs.update({attr: val})
        return attrs

    @classmethod
    def get_text(cls, key):
        try:
            return dict(cls.choices())[key]
        except KeyError:
            return None
        except Exception, e:
            raise e


class ExampleChoices(ChoicesEnum):
    Option1 = 1
    Option1_text = 'Description 1'
    Option2 = 2
    Option2_text = 'Description 2'
    Option3 = 3
    Option3_text = 'Description 3'

ExampleChoices.get_text(1)
ExampleChoices.get_text(ExampleChoices.Option1)
