PyCharm选择性忽略PEP8代码风格警告信息

用了几天的PyCharm，发现确实在编写Python代码上非常好用，但有一点体验不太好，就是代码编写时要按照PEP8代码风格编写，不然会有波浪线的警告信息。解决方法如下：

方法一：

将鼠标移到提示的地方，按alt+Enter，选择忽略（Ignore）这个错误即好。

方法二

打开：File - Settings…… - Editor - Inspections

在python下找到 PEP8 coding style violation，在右边下面的Ignore errors里可以添加忽略的警告信息ID，如下：

如E302就是忽略“expected 2 blank lines, found 0”这个警告（出现在我想给方法上面添加注释的时候）。

警告信息对应的ID在http://pep8.readthedocs.io/en/latest/intro.html#configuration中可找到。
