How to get all values from python enum class?

You can do the following:

[e.value for e in Color]

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]

Use _member_names_ for a quick easy result if it is just the names, i.e.

Color._member_names_

Also, you have _member_map_ which returns an ordered dictionary of the elements. This function returns a collections.OrderedDict, so you have Color._member_map_.items() and Color._member_map_.values() to play with. E.g.

return list(map(lambda x: x.value, Color._member_map_.values()))

will return all the valid values of Color

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']
