python tuple and enum

Question

So I was trying to use enums in python and came upon the following error: When I was using enum as a tuple and giving it two values, I can't access only one value such as tuple[0]

class Rank(Enum):
    ACE = 1
    TWO = 2
    THREE = 3
    FOUR = 4
    FIVE = 5
    SIX = 6
    SEVEN = 7
    EIGHT = 8
    NINE = 9
    TEN = 10
    JACK = 11
    QUEEN = 12
    KING = 13, "King"

print (Rank.KING.value)

and the print is

(13, 'King')

How can I access only one value so I can print 13 or 'King'?

Answer 1

With enum.Enum, the class variable names themselves become the name attribute of the enumerated attributes of the Enum instance, so you don't have to make KING a tuple of value and name:

class Rank(Enum):
    King = 13

print(Rank.King.name) # outputs 'King'
print(Rank.King.value) # outputs 13

If you want to name the class variables with capital letters but have their name values to be mixed-cased, which isn't what Enum is designed for, you would have to subclass Enum and override the name method yourself to customize the behavior:

from enum import Enum, DynamicClassAttribute

class MixedCaseEnum(Enum):
    @DynamicClassAttribute
    def name(self):
        return self._name_.title()

class Rank(MixedCaseEnum):
    KING = 13

print(Rank.KING.name) # outputs 'King'
print(Rank.KING.value) # outputs 13

Answer 2

You have the following possibilites to access 13 or "king":

Rank.KING.value[0]
Rank.KING.value[1]
