python tuple and enum

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

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

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

You can just use indexes as you would use them on an array:

>>> KING = 13, 'King'
>>> KING
(13, 'King')
>>> KING[0]
13
>>> KING[1]
'King'
>>> 

None of the existing answers explained how you might have three (or more) values in an Enum, if you wanted to.

For example, say the initial questioner wanted (13, "K", "king") in the Enum, they would do it like this:

class Rank(Enum):
    K = 13, "King"

    def __init__(self, rank, label):
        self.rank = rank
        self.label = label

The __init__ takes the values and assigns them to the enum members. This means that Rank.K.rank returns 13 and Rank.K.label returns "King".

Although it's not strictly needed in this example, it can be useful to store more than key/value pairs on the Enum.

Note that Rank.K.value still exists, and returns the tuple (13, "King")
