When there is a syntax error in a multi-line f-string, the arrow in the reported syntax error points to the wrong line:

$ cat 
s = ("apricot "
$ python 
  File "", line 1
    s = ("apricot "
SyntaxError: f-string: expecting '}'

Tested with Python 3.7.4 and 3.8.2.

There have been issues about SyntaxError line pointing.  Someone should test with 3.9.0xx to see if fixed but not backported (I cannot today), or search for existing error.

This has been fixed in 3.9.0a6 due to the new parser:

╰─ cat
s = ("apricot "
╰─ ./python.exe
  File "/Users/lysnikolaou/Repositories/cpython/", line 3
SyntaxError: f-string: expecting '}'

Since this issue is now resolved, I'm closing it, after I consulted with pablogsal.
