问题描述

我习惯用这种方式命名 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"

按照 PEP008 的建议?

as is recommended by PEP008?

尾随下划线一定有充分的理由，那是什么?

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

解决方案

正是它在 PEP 中提供的内容:它允许您使用原本会是 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_
