Python中的长生不老药原子？

Question

我正在用python构建一个需要使用小型状态机的项目。我当然可以做一堆像这样的州

__StateOne__ = 0
__StateTwo__ = 1
__StateThree__ = 2
# etc

然后只需要跟踪state=\uu StateOne\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。这是否可能与一些导入或第三方库？你知道吗

Answer 1

使用枚举：

from enum import Enum

states = Enum('<a descriptive name>', 'one two three four')

states.one，states.two，states.three。。。现在有点像原子了。你知道吗
