受 django 启发，让枚举类 label 返回中文

from enum import Enum class XIntegerChoices(Enum): def __new__(cls, value, label): obj = object.__new__(cls) obj._value_ = value obj._label = label return obj def __eq__(self, other): if isinstance(other, int): return other == self.value if isinstance(other, XIntegerChoices): return other.value == self.value return False def __ne__(self, other): return not self.__eq__(other) def __lt__(self, other): if isinstance(other, int): return self.value < other if isinstance(other, XIntegerChoices): return self.value < other.value raise TypeError def __le__(self, other): return self.__eq__(other) or self.__lt__(other) def __gt__(self, other): if isinstance(other, int): return self.value > other if isinstance(other, XIntegerChoices): return self.value > other.value raise TypeError def __ge__(self, other): return self.__eq__(other) or self.__gt__(other) def __hash__(self): return hash(self.value) @property def value(self): return self._value_ @property def label(self): return self._label @classmethod def members(self): return list(self) class Action(XIntegerChoices): CREATED = (1, "创建") if __name__ == '__main__': print(Action.CREATED == 2) print(Action.CREATED.label) print(Action.members()) # False # 创建 # [<Action.CREATED: 1>]

你就不能直接用中文枚举么? 用中文是会要了你的命, 还是丢了你的逼格?
print(Action.创建)

@bthulu 如果是中英文+符号混搭肯定不行，要考虑下代码健壮性，比如应用商店(APP)

Enum 原生支持的

```

class CardTypeEnum(Enum):
ID_CARD = (1, '身份证')
TRAVEL_FOR_HK_MR = (2, '港澳居民来往内地通行证')
TRAVEL_FOR_TW = (3, '台湾居民来往大陆通行证')
PASSPORT = (4, '护照')

def __init__(self, code, text):
self.code = code
self.text = text

print(CardTypeEnum.ID_CARD.text )
```
