枚举的迭代顺序是确定性的吗？

Question

我正在使用 aenum 库。

from aenum import Enum as Aenum

class Availability(Aenum):
    _init_ = "value string"
    PART_TIME = 1, "Part-Time"
    FULL_TIME = 2, "Full-Time"
    BOTH = 3, "Both"

    def __str__(self):
        return self.string

for value, string in Availability:
   print(value)
   print(string)

从经验上看，它似乎是按照定义的顺序进行的，但我很好奇这是否得到保证。

Answer 1

aenum.Enum 是 described 和

a Python stdlib Enum-compatible data type

并且标准库 enum.Enum 是 documented 作为

Enumerations support iteration, in definition order

Answer 2

来自 Github 上的 documentation：

Enumerations support iteration. In Python 3.x definition order is used; in Python 2.x the definition order is not available, but class attribute _order_ is supported; otherwise, value order is used if posible, otherwise alphabetical name order is used.

枚举的迭代顺序是确定性的吗？

Is iteration order over an enum deterministic?
