In python 3.6, code can be evaluated in a string, called an f-string,
see: https://www.python.org/dev/peps/pep-0498/
It would be nice if python-mode would not syntax highlight the code in
the f-string as a string, and instead use regular syntax highlighting.
eg:
print(f'Test {} me!'.format(2 + 2))
can be written as:
print(f'Test {2 + 2} me!')
I noticed php-mode (which had something like this for many years)
does for for PHP's strings, eg: "Test {$2 + 2} me!"

It was recommended I send in a feature request:

I wonder if MagicPython project could be useful to implement this.
Currently, it has a pretty comprehensive test suit:
https://github.com/MagicStack/MagicPython/tree/master/test/fstrings
And it has f-strings grammar defined in a yaml file:
https://github.com/MagicStack/MagicPython/blob/master/grammars/src/pyfstring.inc.syntax.yaml
At the very least, it could serve as a widely adopted reference (Atom,
Sublime, and VS Code use it).
I also wrote a very naive and wrong hack for personal use, based on
php-mode:
```
(defconst python-f-string-regexp
"{[[:word:]]+\\.?[[:word:]]+?}")
(defun python-f-string-font-lock-find (limit)
(while (re-search-forward python-f-string-regexp limit t)
(when (python-syntax-comment-or-string-p)
(put-text-property (match-beginning 0) (match-end 0)
'face 'font-lock-variable-name-face)))
nil)
(with-eval-after-load 'python
(font-lock-add-keywords
'python-mode
`((python-f-string-font-lock-find))
'append))
```
(I'm really sorry, I don't know how to format monospaced text in debbugs)

Not directly, unless we port Emacs to JavaScript.

That's true.

No worries, check https://debbugs.gnu.org/30750#8, your whole post is
already monospaced :)
(but posting code as attachment often works better, because gmail tends
to add line wrapping to the email body)

I just pushed a change to the `master` branch of Emacs which should
do that.
