Printing all member names of a enum class

Question

class MyValues(enum.Enum):
    value1 = 1
    value2 = 2
    value3 = 1

print(MyValues._member_names_)

Output would be a list with only the first two members [value1,value2]

I would also like to have value3 in that list, i tried with aenum with NoAlias setting but did not work. Is there any way to get all members even if they have duplicate values?

You can use `MyValues.__members__` to get a dictionary of name-Enum mapping. So to get only the names, you'd do `list(MyValues.__members__)` — h4z3, Jan 16 '23 at 13:59

@PersianMan: because sometimes a single value can have different names. — Ethan Furman, Jan 16 '23 at 16:55

_member_names_ is not part of the Enum documented public API. You should not use it.

__members__ is what you're looking for. It's a mapping from member names to members, including all aliases. You can use list(MyValues.__members__) if you just want a list of the names.
