python: pycodestyle (ex pep8)与pylint的严格性

Question

我有一个python项目，我想检查它是否符合PEP8。

我的setyp.cfg如下：

[pycodestyle]
count = True
ignore = E266, W504
max-line-length = 80
statistics = True
exclude = .venv,./build%

经过一些清理之后，我的pycodestyle检查现在没有错误，也没有警告(当然，忽略了那些错误)

~/Workspace/my-app  master ✔                                                                                                                        2h36m
➢  pycodestyle .
(.venv)
~/Workspace/my-app  master ✔

但是，对我的项目运行pylint会产生大量错误：

(中的一些只是为了演示而跟随)

************* Module somemodule.commands

                            format(gcp_project)))

src/somemodule/commands.py:5:0: C0411: standard import "from subprocess import Popen, PIPE" should be placed before "import click" (wrong-import-order)

这两个工具怎么会产生如此偏离的结果呢？

Answer 1

我只是在这个问题上绊倒了，我亲自比较了一下pycodestyle和pylint。

简而言之，答案是pycodestyle是pylint的“子集”。让我引用基本python工具的一些话

• Pycodestyle (以前的PEP8)是官方的linter工具，用于根据PEP8 python的样式惯例检查python代码。
• Pylint是一个python，它检查源代码，并充当bug和质量检查器。它有比PEP8(Python )更多的验证检查和选项。
  • 这是python中最常用的工具。
  • 它包括以下特性：
    • 检查每一行的长度
    • 根据项目的编码标准检查变量名称是否格式良好
    • 检查声明的接口是否真正实现。
    • ..。
