PyCharm代码风格警告问题
PyCharm使用的是PEP8代码风格,所以当出现不不符合PEP8代码风格便会出现警告信息
block comment should start with #
解决方法(以下是在Mac解决方法,其他平台类似)本文来源:Seakee.top. 未经允许不得转载.
方法一 使用PyCharm格式化代码
1、选中出现警告的代码块,使用快捷键option(alt)+command+L
2、也可以直接在选中代码后执行Code>>Reformat Code
方法二忽略警告
1、将鼠标移到提示的地方,按option(alt)+Enter,选择忽略(Ignore)这个错误即好。本文来源:Seakee.top. 未经允许不得转载.
2、打开PyCharm>>Preference>>Editor>>PEP 8 coding style violation,然后再下面Options添加要忽略的错误代码,最后OK就行。
警告信息对应的ID在http://pep8.readthedocs.io/en/latest/intro.html#configuration中可找到。
