Python enum multiple values | Example code

Use MultiValueEnum to get enum multiple values in Python. You have to install and import aenum library and this is the easiest way. To access the values of an enumeration, you can use dot notation:

Python enum with multiple values example

Simple example code.

from aenum import MultiValueEnum


class DType(MultiValueEnum):
    float32 = "f", 8
    double64 = "d", 9


print(DType("f"))
print(DType(9))

Output:

An alternative way to get enum multiple values

from enum import Enum


class DType(Enum):
    float32 = "f", 8
    double64 = "d", 9

    def __new__(cls, *values):
        obj = object.__new__(cls)
        # first value is canonical value
        obj._value_ = values[0]
        for other_value in values[1:]:
            cls._value2member_map_[other_value] = obj
        obj._all_values = values
        return obj

    def __repr__(self):
        return '<%s.%s: %s>' % (
            self.__class__.__name__,
            self._name_,
            ', '.join([repr(v) for v in self._all_values]),
        )


print(DType("f"))
print(DType(9))

Output:

DType.float32
DType.double64

You can also iterate over the values of an enumeration using a for loop:

from enum import Enum

class Color(Enum):
    RED = (255, 0, 0)
    GREEN = (0, 255, 0)
    BLUE = (0, 0, 255)

for color in Color:
    print(color)

To access the values of an enumeration, you can use the .value attribute:

Color.RED.value
