  # pink = 'red'    # 在使用unique装饰器后这里会报错     duplicate values found in <enum 'ColorEnum'>: pink 
  
# 打印属性
>>> print(ColorEnum.RED)
ColorEnum.RED
>>> print(ColorEnum.RED.value)
red
>>> print(ColorEnum.RED.name)
RED

# 枚举全部变量
ColorEnum._member_names_        # ['RED', 'GREEN', 'BLUE']

# 输出所有变量的值:键字典
ColorEnum._value2member_map_    # {'red': <ColorEnum.RED: 'red'>, 'green': <ColorEnum.GREEN: 'green'>, 'blue': <ColorEnum.BLUE: 'blue'>}

# 得到所有枚举
ColorEnum.__members__.items()   # ColorEnum.__members__.items() dict_items([('RED', <ColorEnum.RED: 'red'>), ('GREEN', <ColorEnum.GREEN: 'green'>), ('BLUE', <ColorEnum.BLUE: 'blue'>)])
