bug#67529: 29.1; Python: syntax category of code in f-strings marked as string

[Daniel Fleischer]

Hi, in python f-strings can have python code inside them:

f"Two plus two is {2+2}"
f"The value of a is {a}"
f"The first item in arr is {arr[0]}"

The function `python--font-lock-f-strings` correctly fontify 
what's inside the
{} as code.  

However syntax analysis show the content inside {} as string; run
`(syntax-ppss-context (syntax-ppss (point)))` to see. 

This has semantic implications, for example the package 
`smart-scan` can jump
between occurrences of a symbol but it won't identify the symbol 
in a
string/comment. Maybe there are other packages which use this 
syntax
information.
