为什么 Pylint 反对单字符变量名? [英] Why does Pylint object to single-character variable names?

问题描述

我仍然习惯于 Python 约定并使用 Pylint 使我的代码更加 Pythonic，但我对 Pylint 不喜欢单字符变量名这一事实感到困惑.我有几个这样的循环:

I'm still getting used to Python conventions and using Pylint to make my code more Pythonic, but I'm puzzled by the fact that Pylint doesn't like single character variable names. I have a few loops like this:

for x in x_values:
   my_list.append(x)

当我运行 pylint 时，我得到 无效名称x"对于类型变量(应该匹配 [a-z_][a-z0-9_]{2,30} - 这表明有效的变量名称必须在 3 到 31 个字符之间，但我已经看过了通过 PEP8 命名约定，我看不到关于单个小写字母的任何明确内容，我确实看到很多使用它们的示例.

and when I run pylint, I'm getting Invalid name "x" for type variable (should match [a-z_][a-z0-9_]{2,30} -- that suggests that a valid variable name must be between 3 and 31 characters long, but I've looked through the PEP8 naming conventions and I don't see anything explicit regarding single lower case letters, and I do see a lot of examples that use them.

我在 PEP8 中是否缺少某些东西，或者这是 Pylint 独有的标准吗?

Is there something I'm missing in PEP8 or is this a standard that is unique to Pylint?

推荐答案

Pylint 不仅检查 PEP8 建议.它也有自己的建议，其中之一就是变量名应该是描述性的，不能太短.

Pylint checks not only PEP8 recommendations. It has also its own recommendations, one of which is that a variable name should be descriptive and not too short.

您可以使用它来避免此类短名称:

You can use this to avoid such short names:

my_list.extend(x_values)

或者调整 Pylint 的配置告诉 Pylint 什么变量名好.

Or tweak Pylint's configuration to tell Pylint what variable name are good.
