[issue40449] multi-line f-string, syntaxerror points to wrong line

[Lysandros Nikolaou]

Lysandros Nikolaou  added the comment:

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

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

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.

[issue40449] multi-line f-string, syntaxerror points to wrong line

[Gerrit Holl]

New submission from Gerrit Holl :

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 mwe.py 
s = ("apricot "
 "pineapple"
 f"shallot{")
$ python mwe.py 
  File "mwe.py", line 1
s = ("apricot "
^
SyntaxError: f-string: expecting '}'

Tested with Python 3.7.4 and 3.8.2.
