Using a classmethod with   members    class RoleNames str  Enum       AGENT    quot agent quot      USER    quot user quot      PRIMARY USER    quot primary user quot      SUPER USER    quot super user quot            classmethod     def list roles cls           role names    member value for role  member in cls   members   items            return role names   gt  gt  gt  role names   RoleNames list roles    gt  gt  gt  print role names   or if you have multiple Enum classes and want to abstract the classmethod  class BaseEnum Enum        classmethod     def list roles cls           role names    member value for role  member in cls   members   items            return role names   class RoleNames str  BaseEnum           AGENT    quot agent quot      USER    quot user quot      PRIMARY USER    quot primary user quot      SUPER USER    quot super user quot        class PermissionNames str  BaseEnum       READ    quot updated at quot      WRITE    quot sort by quot      READ WRITE    quot sort order quot

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 names  items   and Color  member names  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

So the Enum has a   members   dict   The solution that  ozgur proposed is really the best  but you can do this  which does the same thing  with more work   color value for color name  color in Color   members   items     The   members   dictionary could come in handy if you wanted to insert stuff dynamically in it    in some crazy situation    EDIT  Apparently   members   is not a dictionary  but a map proxy  Which means you can t easily add items to it   You can however do weird stuff like MyEnum   dict     member map     new key      new value   and then you can use the new key like MyEnum new key     but this is just an implementation detail  and should not be played with  Black magic is payed for with huge maintenance costs

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

class enum Enum is a class that solves all your enumeration needs  so you just need to inherit from it  and add your own fields  Then from then on  all you need to do is to just call it s attributes  name  amp  value   from enum import Enum  class Letter Enum      A   1    B   2    C   3  print  i name  i value for i in Letter     prints   A   1   B   2   C   3
