在Ipython中使用Pylint(Jupyter-Notebook) [英] Using Pylint in Ipython (Jupyter-Notebook)

问题描述

我想在使用Jupyter-Notebook时运行Pylint或任何等效版本.有没有办法以这种方式安装和运行Pylint?

I want to run Pylint or any equivalent while using Jupyter-Notebook. Is there a way to install and run Pylint this way?

推荐答案

pycodestyle 与Jupyter Notebook的pylint等效，它可以根据PEP8样式指南检查代码.

pycodestyle is an equivalent of pylint for Jupyter Notebook which is able to check your code against the PEP8 style guide.

首先，您需要通过键入以下命令在jupyter notebook中安装pycodestyle，

First, you need to install the pycodestyle in jupyter notebook by typing this command,

!pip install pycodestyle pycodestyle_magic

在jupyter笔记本的单元格中运行此命令. 成功安装后，您必须像这样在Jupyter Notebook单元中加载魔法，

Run this command in a cell of jupyter notebook. After successful installation, you have to load the magic in a Jupyter Notebook cell like this,

%load_ext pycodestyle_magic

然后，您必须在要根据PEP8标准调查代码的单元格中使用pycodestyle.

Then, you have to use pycodestyle in a cell in which you want to investigate your code against PEP8 standards.

下面是一些示例，可以使您更清楚地了解

Below are some examples for more and clear understanding,

%%pycodestyle
a=1

输出:pycodestyle会给您此消息，

2:2: E225 missing whitespace around operator

另一个例子，

%%pycodestyle
def square_of_number(
     num1, num2, num3, 
     num4):
    return num1**2, num2**2, num3**2, num4**2

输出:

2:1: E302 expected 2 blank lines, found 0
3:23: W291 trailing whitespace
