Color+list RED+list GREEN+list BLUE 步骤3:访问 Enum 值 现在我们可以通过 Enum 成员来访问其对应的列表值。 # 获取 Color.RED 的值red_value=Color.RED.valueprint("红色的值:",red_value)# 访问列表中的元素hex_value=red_value[0]color_name=red_value[1]print("红色的十六进制值:",hex_value)prin...

python enum转list 文心快码BaiduComate 在Python中,enum模块允许你定义枚举类型,这些类型由一组具名的常量组成。要将enum转换为list,你可以通过列出枚举的所有成员来实现。下面是一个详细的步骤说明,包括代码示例: 创建一个Python enum类: 你可以使用enum.Enum来定义一个枚举类。例如,定义一个表示星期的枚举类: ...
from enum import IntEnum # 通过IntEnum创建支持整数比较的枚举 class Size(IntEnum): S = 1 M = 2 L = 3 XL = 4 print(Size.S > Size.M) 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. False 1. 强制唯一值 from enum import Enum, unique # 当成员值不唯一,如果不添加unique装饰器,则代...
class FourSeasons(Enum): spring = 1 summer = 2 autumn = 3 winter = 4 print(list(FourSeasons)) for name, value in FourSeasons.__members__.items(): print(name, value) print(FourSeasons['winter']) # winter = 4 修改为3会报错 ValueError: duplicate values found in <enum 'FourSeasons'...
1. Python中的Enum类 from enum import Enum class Season(Enum): SPRING = 1 SUMMER = 2 AUTUMN = 3 WINTER = 4 # printing enum member as string print(Season.SPRING) # printing name of enum member using "name" keyword print(Season.SPRING.name) ...
