Trying to make a PR for this, but needs help! I'm not quite professional in vim syntax writing. 😞

I need to make Vim to treat above <any python expression>
part like a just normal Python expression. The only rules for them are:
f"{(lambda: 1)()}"
A nice test case would be something like f"{var} plain {expr1 if True or False else expr2} text {var!r} {dictob['key']:.2f} abc {123_34E+2:g} {(lambda: 1)()}"
. Somebody please help me to figure out how to do this! 😁
This has been fixed over at the fork vim-python/python-syntax.
Python 3.6 has reached its last beta where its features are frozen now. It introduces a new syntactic element: f-string literals. https://docs.python.org/3.6/whatsnew/3.6.html#whatsnew36-pep498
In f-string literals, the content inside braces are treated as real Python expressions with optional format string after a colon character like in
format()
protocol. The expression expansion may be done inside the format string as well though. (See the examples in the above link.)Let's add support for this.
