3.4枚举应该使用UPPER_CASE_WITH_UNDERSCORES吗？ [英] Should 3.4 enums use UPPER_CASE_WITH_UNDERSCORES?

问题描述

如文档所述，枚举是绑定到唯一的恒定值的一组符号名称（成员）。 PEP8 表示常量通常被命名为 UPPER_CASE ，我应该在Python 3.4 枚举中使用此符号吗？如果是，为什么文档中的示例使用 lower_case ？

As the documentation says, an enumeration is a set of symbolic names (members) bound to unique, constant values. The PEP8 says that constants are usually named as UPPER_CASE, should I use this notation in Python 3.4 enums? If yes, why the examples in the docs are using lower_case?

推荐答案

更新

BDFL（仁慈的生命独裁者）说了，并且 枚举文档 已更改为反映所有大写成员名称。

The BDFL (Benevolent Dictator For Life) has spoken, and the Enum documentation has changed to reflect all upper-case member names.

[previous]文档中的示例是小写字母，主要是因为Enum基于的一个已有模块之一使用了小写字母（或者至少是

The examples in the [previous] docs are lower-case primarily because one of the preexisting modules that Enum was based on used lower-case (or at least its author did ;).

我对枚举的用法通常类似于：

My usage of enum has usually been something along the lines of:

class SomeEnum(Enum):
    ... = 1
    ... = 2
    ... = 3
globals().update(SomeEnum.__members__)

所以我想说哪种风格对您来说都更舒适-但要选择一种风格并保持一致。

So I would say whichever style feels more comfortable to you -- but pick a style and be consistent.
