New submission from Terry J. Reedy <tjre...@udel.edu>:
Spinoff from #41064. In current python, the f'{*x}' traceback ends with
(*x)
^
SyntaxError: f-string: can't use starred expression here.
For f'{**x}', the message is "f-string: invalid syntax" and the ^ is also under
the 2nd character in the replacement expression actually parsed (with a
restricted grammar).
The Python error handler must special case a syntax error message beginning
with 'f-string:' and search the input line for {...} and add its offset.
IDLE currently highlights "'", the 2nd char of the original code, instead of
'*', the 2nd char of the e.text replacement. It needs to also adjust the
offset.
