Enums, further in Python

auto, StrEnum and Flag cover most of what enums are for.

from enum import Flag, StrEnum, auto


class Theme(StrEnum):
    DEFAULT = auto()
    MONOKAI = auto()


class Mode(Flag):
    EDITOR = auto()
    TIMED = auto()
    QUIET = auto()


print(Theme.MONOKAI, Theme.MONOKAI == "monokai")
combo = Mode.EDITOR | Mode.TIMED
print(combo, Mode.TIMED in combo, Mode.QUIET in combo)
print([m.name for m in Mode if m in combo])

How it works

1. auto() assigns the values so you cannot mistype one.
2. StrEnum members are strings, so they serialize directly.
3. Flag members combine with the bitwise operators.
