ANSWER 2

Based on the answer by @Jeff, refactored to use a classmethod so that you can reuse the same code for any of your enums:

from enum import Enum

class ExtendedEnum(Enum):

    @classmethod
    def list(cls):
        return list(map(lambda c: c.value, cls))

class OperationType(ExtendedEnum):
    CREATE = 'CREATE'
    STATUS = 'STATUS'
    EXPAND = 'EXPAND'
    DELETE = 'DELETE'

print(OperationType.list())

Produces:

['CREATE', 'STATUS', 'EXPAND', 'DELETE']

You can use IntEnum:

from enum import IntEnum

class Color(IntEnum):
   RED = 1
   BLUE = 2


print(int(Color.RED))   # prints 1

To get list of the ints:

enum_list = list(map(int, Color))
print(enum_list) # prints [1, 2]

To use Enum with any type of value, try this:
Updated with some improvements... Thanks @Jeff, by your tip!

from enum import Enum

class Color(Enum):
    RED = 1
    GREEN = 'GREEN'
    BLUE = ('blue', '#0000ff')

    @staticmethod
    def list():
        return list(map(lambda c: c.value, Color))

print(Color.list())

As result:

[1, 'GREEN', ('blue', '#0000ff')]
