Нужно это для директив препроцессору, располагающихся в конце файла.
Вот кто бы объяснил мне, при чём тут директивы и скобка с начала строки?

PEP8 «No newline at end of file»
It means exactly what it says. There is no recognizable newline at the end of the file. The last character is the ) . or maybe a TAB, or SPACE, or a line terminator for a different platform. Solution: open the file in an editor, add a newline at the end, save and close the file.

I’ve tried that, I had a new line after it and I get «blank line contains whitespace» error
Apr 23, 2022 at 3:00
So get rid of the whitespace!!
Apr 23, 2022 at 3:01
@Ryu That’s a different error. Ultimately what you should do is set up your editor to do all of this for you: add a trailing newline if there isn’t one, and strip trailing whitespace. For example for Atom, there’s a package called whitespace that’ll do that.

Solved. Thanks for your help. I wasn’t using my common sense

So what you had was a line consisting of white space (SPACE or TAB characters) followed by a newline. Use your editor to get rid of that line.
The style checker wants the last line of the file to end with the newline character, and to have no trailing whitespace on that line.
No Newline at End of File
Have you ever seen “No newline at end of file” in your git diffs? Us, too.
~/.dotfiles% git diff diff --git a/vimrc b/vimrc index 7e31913..a8b5f95 100644 --- a/vimrc +++ b/vimrc @@ -2,4 +2,4 @@ let configs = split(glob("~/.vim/configs/*"), "\n") for filename in configs execute 'source ' filename -endfor +endfor \ No newline at end of file Why does this happen and what does it mean?
Try it in your shell
Here I have made a text file and, by definition, a non-text file:
~% echo foo > text-file ~% od -c text-file 0000000 f o o \n 0000004 ~% wc -l text-file 1 text-file ~% echo -n foo > binary-file ~% od -c binary-file 0000000 f o o 0000003 ~% wc -l binary-file 0 binary-file If you open each file in vim, they will display similarly. The intuition behind what vim is doing is “separate each line with a line break”, which is different from “display each \n as a line break”.
However, the binary-file will cause vim to display [noeol] in its status line (with the default status line).
History lesson
This comes from an old C decision that has been passed down through Unix history:
A source file that is not empty shall end in a new-line character, which shall not be immediately preceded by a backslash character.
Since this is a “shall” clause, we must emit a diagnostic message for a violation of this rule.
So, it turns out that, according to POSIX, every text file (including Ruby and JavaScript source files) should end with a \n , or “newline” (not “a new line”) character. This acts as the eol , or the “end of line” character. It is a line “terminator”.
Following the rules in your editor
You can make sure you follow this rule easily:
- For Vim users, you’re all set out of the box! Just don’t change your eol setting.
- For Emacs users, add (setq require-final-newline t) to your .emacs or .emacs.d/init.el file.
- For Android Studio, RubyMine, PyCharm, and other IntelliJ, set “Ensure line feed at file end on Save” under “Editor.”
- For Atom, you’re also all set out of the box. Keep that via the Whitespace plugin.
- For VS Code, set «files.insertFinalNewline»: true .
- For Sublime, set the ensure_newline_at_eof_on_save option to true .
- For TextMate, you can install the Avian Missing Bundle and add TM_STRIP_WHITESPACE_ON_SAVE = true to your .tm_properties file.
