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。
