? 一个项目大多都是由一个团队来完成，如果没有统一的代码规范，那么每个人的代码的风格必定会有很大的差别。且不说会存在多个人同时开发同一模块的情况，即使是分工十分明晰的项目，等到要整合代码的时候也会非常头疼（亲身体会）。大多数情况下，并非程序中有复杂的算法或是复杂的逻辑，而是由于风格的不同，去读别人的代码实在是一件痛苦的事情。统一的风格使得代码可读性大大提高了，人们看到任何一段代码都会觉得像自己写的差不多。显然的，规范的代码在团队的合作开发中是非常有益而且必要的。
? 下面将介绍pylint如何在django项目中实现代码风格检查。
? Pylint 是一个 Python 代码分析工具，它分析 Python 代码中的错误，查找不符合代码风格标准（Pylint 默认使用的代码风格是 PEP 8）和有潜在问题的代码。
pylint的安装十分简单，在命令行中执行
pip install pylint
即可完成安装
在看此方法前，请务必确认Django项目正确地在PyCharm中创建了。
? 打开PyCharm，左上角点击File--Settings，打开设置页面，再选择Plugins，进入插件市场，搜索Pylint：
? 点击Install下载，下载完成后会提示重启IDE，按提示重启即可
? 这里可以通过命令行直接生成配置文件加以修改，也可以直接参考我的.pylintrc文件。
? 命令行生成文件方法：
? 在任意目录打开命令行，执行：
? pylint --persistent=n --generate-rcfile > .pylintrc
? 生成的文件大概有400多行，每一个配置选项都有详细的英文注释，涉及到：
Django项目推荐禁用的规则有：
我的.pylintrc：
# lint Python modules using external checkers.

现在pylint插件应该会出现在PyCharm的左下角：
点击设置：
Path to Pylint executable中Pylint的exe文件应该会自动检测并为你配置好，如果没有的话照着我的路径配置一下
Path to pylintrc就是选择我们刚刚生成好的.pylintrc文件的路径，推荐将其放于项目的根目录
Arguments是参数设置，我这么配置的原因是希望它跳过数据库迁移文件，因为数据库迁移文件的代码风格一定是有问题的，而且是自动生成的。
到这里配置就完成了。
? 点击检查整个工程的按钮，等待检查完成。
? 若显示Pylint found no problems，则表明你的工程代码风格已经完全满足pylint的要求，否则可以根据提示按要求修改。
? 如果不使用PyCharm，那我们也可以通过命令行来检查，检查单个文件的网上教程有很多，这里就不再赘述，仅介绍检查整个工程的方法。
? 请根据方法1中的第二步，配置好.pylintrc文件并放置于项目根目录中后，在根目录中添加__init__.py文件（将整个工程看作一个包），再在根目录下命令行执行：
pylint [你的项目文件夹名] --ignore-patterns=00.*py
即可实现对整个工程的检查：
