PyCharm：选择性忽略 PEP8 警告

PyCharm 是个很强大的 python IDE，PEP 8 的告警提示也很好用，但是函数名不能包含大写字母等少数几个规范真心觉得不好，作为一名处女座强迫症患者，代码下面的波浪线这种东西是绝对不允许存在的。

File -> Settings -> Editor -> Inspections -> 右侧Python

在 Ignored errors 中添加要忽略的告警ID。注意，要区分是属于 coding 还是 naming。

PEP 8 coding style violation 的告警ID查看 https://pep8.readthedocs.io/en/latest/intro.html#error-codes

PEP 8 naming convention violation 的告警ID查看 https://pypi.org/project/pep8-naming/

code	sample message
N801	class names should use CapWords convention
N802	function name should be lowercase
N803	argument name should be lowercase
N804	first argument of a classmethod should be named ‘cls’
N805	first argument of a method should be named ‘self’
N806	variable in function should be lowercase
N807	function name should not start or end with ‘__’
N811	constant imported as non constant
N812	lowercase imported as non lowercase
N813	camelcase imported as lowercase
N814	camelcase imported as constant

如上图，添加 N802、N803、N806 的忽略，然后，这个世界就清净了。
