1、PEP 8: W292 no newline at end of file 这个意思是:W292文件末尾没有换行符 解决:在代码最后一行加一个回车即可 例图: 2、PEP 8: W391 blank line at end of file 这个意思是:W391文件末尾的空行 解决:代码最后有两行空行,删除一行即可 例图: 3、PEP 8: E221 multiple spaces before operator ...
系统提示一个刺眼的波浪号,我就很纳闷,不知道是哪里出错了,当鼠标放上去的时候系统提示no newline at end of file翻译过来就是“文件结尾没有换行符”,换行符不是、\n \t \* 这些吗,为什么要在结尾加换行符,还不明白,百度后发现了解决办法,就是在最后一行最后按下回车。
1、no newline at end of file 解决:文件尾部没有新起一行,光标移到最后回车即可,而且不能有tab缩进 2、continuation line over-indented for visual indent 解决:括号内的参数很多的时候, 为了满足每一行的字符不超过79个字符, 需要将参数换行编写, 这个时候换行的参数应该与上一行的括号对齐。

The Python interpreter does not force you to specify the type of your function’s arguments or the return value. Depending on the programming languages you’ve used before, this may well freak you out. Don’t let it. Python lets you send anyobjectas a argument, and pass back anyobjectas...
