Attempting to parse the following python code results in a fairly unhelpful syntax error along with an incorrect line number being reported:
#a dodgy f-string
def dodgy(**kwargs):
print(f"{**kwargs}")
The result:
File "<fstring>", line 1
(**kwargs)
^
SyntaxError: invalid syntax

The line number has been fixed in python 3.9:
File "...\foo.py", line 5
(**kwargs)
^
SyntaxError: f-string: invalid syntax
The error message should improve when we move parsing of f-strings into the parser. I doubt we'd put in the effort to do anything before then.

Ah, that makes sense, thank you for the info. The line number is probably the most important piece of information here anyway. It sounds like the syntax error string is already planned and as such this is probably a duplicate. Please close if this is the case. Cheers |

There are still variations of this issue in python 3.10 - the line nr is correct - in script attached it's line 2 (the attached script is otherwise the same):
f'{ 1_a }'
resulting in:
File "test.py", line 1
( 1_a )
^
SyntaxError: invalid decimal literal
or is this a different but similar bug? Can this bug be reopened or should I file a new bug?
