python的枚举类型

# 导入包
from enum import IntEnum


# 定义枚举
class Season(IntEnum):
    Spring = 1
    Summer = 2
    Autumn = 3
    Winter = 4

# 枚举类型转字符串
Season.Spring.name

# 枚举类型转数字
Season.Spring.value

# 字符串转枚举
Season['Spring']

# 数字转枚举
Season(1)

# 遍历枚举成员
for elem in Season:
    elem.name
    elem.value
    elem

# 比较大小
Season.Summer > Season.Spring
