Python 命名中尾随下划线的优势是什么? [英] What's the advantage of a trailing underscore in Python naming?

问题描述

我习惯这样命名 Python 参数:

I am used to naming Python arguments in this way:

my_argument='foo'

如果我这样做有什么好处:

what's the advantage if I do this instead:

my_argument_='foo" 

是 PEP008 推荐的吗?

as is recommended by PEP008?

尾随下划线一定有很好的理由，那是什么?

There must be a good reason for the trailing underscore, so what is it?

推荐答案

正是它在 PEP 中给出的内容:它允许您使用一些本来是 Python 关键字的东西.

Exactly what it gives in the PEP: it allows you to use something that would otherwise be a Python keyword.

as_
with_
for_
in_
